What is the Reach173 test report?

admin — Fri, 27 Jun 2025 00:10:25 +0000

The REACH 173 test report is a compliance report issued after testing chemical substances in products based on the relevant requirements of Article 173 of the EU “Registration, Evaluation, Authorization and Restriction of Chemicals” (REACH Regulation). The following is a detailed description of the regulatory background, core content, test points and report functions:

### **I. Regulatory background and purpose**
REACH Regulation (EC 1907/2006) is an important EU regulation on chemical management, aimed at protecting human health and environmental safety and promoting the safe use of chemicals. Article 173 clarifies the restrictions on certain hazardous chemicals and stipulates that if a product contains chemical substances restricted by the regulation and exceeds the limit, it will be prohibited from being sold in the EU market. The core purpose of the REACH 173 test report is to prove that the product meets these restrictions and ensure its compliance in the EU market.

### **Second, core content of testing**
#### 1. **Restricted substances list**
The restricted substances list (Annex XVII) of REACH 173 is updated regularly, covering hundreds of chemical substances that are harmful to human health or the environment. Common categories include:
– **Heavy metals and their compounds**: such as lead, cadmium, mercury, hexavalent chromium, etc. (for example, the cadmium content in leather is limited to ≤0.1%).
– **Phthalates**: such as DEHP, BBP, DBP, DIBP, etc. (some phthalates in toys or children’s products are limited to ≤0.1%).
– **Azo dyes**: azo dyes that can decompose carcinogenic aromatic amines (limit ≤30ppm).
– **Flame retardants**: such as polybrominated biphenyls (PBB), polybrominated diphenyl ethers (PBDE), etc. (restricted use in electronic and electrical products).
– **Other hazardous substances**: formaldehyde, asbestos, nickel release, pentachlorophenol, etc. (for example, the formaldehyde content in textiles is limited from 20ppm to 300ppm depending on the purpose).

#### 2. **Test objects and scope**
– **Product types**: Almost all consumer products, including electronic appliances, toys, textiles, leather, furniture, building materials, cosmetic packaging, etc.
– **Test focus**: Analyze the content of restricted substances in the material components of the product, such as coatings, plastics, metals, rubber, fabrics, etc.

### **III. Limit standards and test methods**
#### 1. **Limit requirements**
The limit values of different substances in different products vary greatly, for example:
– **Lead**: The lead content limit in electronic and electrical products is ≤0.1% (except for exemptions); the lead content limit in toy materials is ≤90ppm (0.009%).
– **Cadmium**: The cadmium content in general consumer products is limited to ≤0.01% (100ppm), and specific materials such as plastics and coatings may have more stringent requirements.
– **Phthalates**: The total limit of DEHP, BBP, DBP, and DIBP in toys and child care products is ≤0.1%.

#### 2. **Detection methods**
Common standards include:
– **Heavy metal detection**: such as EN 1122 (determination of cadmium in plastics), ISO 17294 (heavy metal detection in water quality), USEPA 3050B (heavy metal digestion in solid waste), etc.
– **Organic compound detection**: such as gas chromatography-mass spectrometry (GC-MS), high performance liquid chromatography (HPLC), etc., used to analyze phthalates, azo dyes, etc.

### **Fourth, the role of the report and applicable scenarios**
#### 1. **Required documents for market access**
– If companies want to sell products to the EU market, the REACH 173 test report is a key document to prove that the product complies with the restrictions of Annex XVII, which can avoid fines (up to 4% of the company’s global turnover), product recalls or market bans due to violations.
– E-commerce platforms (such as Amazon Europe and eBay) usually require sellers to provide this report to ensure product compliance.

#### 2. **Supply chain compliance management**
– The report can help companies screen for hazardous substances in raw materials and components, promote supply chain source control, and reduce compliance risks.
– For traders or brand owners, the report is also an important basis for proving product safety to customers and enhancing market trust.

### **V. Differences from other tests**
– **Differences from California 65**: REACH 173 is an EU regulation, covering a wider range of substances, with more detailed limits, and emphasizing the registration and evaluation of all links in the supply chain; California 65 is a local regulation in California, USA, focusing on carcinogenic and reproductive toxic substances, with warning labels and limit control as the main focus.
– **Differences from REACH SVHC**: The REACH SVHC (Substances of Very High Concern) list is used for notification and information disclosure, while REACH 173 is a mandatory restriction. If the limit is exceeded, sales are prohibited. The two belong to different compliance requirements in the regulations (SVHC focuses on transparency, and 173 focuses on prohibition of use).

### **Summary**
REACH 173 test report is an important compliance document for EU market access. By testing restricted substances in products, it ensures that they meet the limit requirements of Annex XVII, helps companies avoid legal risks, and ensures the legal circulation of products in the EU. Since regulations will continue to be updated, companies need to pay attention to changes in the restricted substance list and update tests in a timely manner to meet the latest requirements.

What is the California 65 Test Report?

admin — Fri, 27 Jun 2025 00:08:43 +0000

The California 65 Test Report is a report issued after testing the product for relevant chemical substances in accordance with the requirements of California Proposition 65 (also known as the California Hazardous Substances Release Inventory of 1986 or the Safe Drinking Water and Toxic Enforcement Act). The details are as follows:
Testing purpose: The proposal aims to protect California residents from chemicals that may cause cancer or reproductive toxicity, and to protect California’s drinking water resources from known carcinogenic, birth defect-causing or other reproductive toxic chemicals. The test report is used to prove whether the product meets the relevant requirements of California Proposition 65 and ensure that the product will not cause harm to human health.
Testing items: mainly include phthalates (such as DEHP, BBP, DBP, etc.), heavy metals (such as lead, cadmium), formaldehyde, flame retardants, bisphenol A (BPA), etc.
Limit standards: The lead content limit of general parts shall not exceed 100ppm (0.01%), the lead content limit of paint shall not exceed 90ppm (0.009%), and the phthalate limit shall not exceed 1000ppm (0.1%), etc. The standards usually adopt the EPA standards.
Report function: For companies selling products in California, the test report is an important basis for proving the compliance of their products, which can avoid the risks of lawsuits and high compensation due to the lack of warning labels for products containing excessive harmful substances. At the same time, for sellers on e-commerce platforms, such as Amazon, sellers are sometimes required to provide California 65 test reports to ensure that products can be legally sold on the platform.

What does screen printing for logo printing do?

admin — Thu, 26 Jun 2025 13:34:47 +0000

In logo printing, screen printing is a key step in making screen printing plates. Its purpose
is to accurately transfer the designed logo pattern to the printing material. The following
are the specific functions and processes of screen printing:
Function
Forming a pattern template: The process of screen printing is to create a pattern template
on the screen that matches the logo design exactly. By processing the screen, the mesh
holes in the pattern part can allow ink to pass through, while the mesh holes in the
non-pattern part are blocked, so that the pattern can be accurately reproduced during
printing.
Control ink transfer: The size and shape of the mesh holes on the screen determine the
amount and accuracy of ink transfer. A suitable screen can ensure that the ink passes
through the mesh holes evenly and is printed on the substrate with appropriate thickness
and clarity, thus presenting a clear and full logo pattern.
Process
Prepare the screen: Select a suitable screen. The mesh count and material of the screen
are usually determined according to the printing requirements and the characteristics of
the substrate. Common screen materials include nylon, polyester and stainless steel.
Then stretch the screen tightly on the screen frame to ensure uniform screen tension.
Coating photosensitive glue: evenly coat a layer of photosensitive glue on the screen.
Photosensitive glue is a light-sensitive material that will react chemically after exposure to
form a colloid with a certain hardness and water resistance.
Exposure: Place the designed logo pattern negative (usually film) on the screen coated
with photosensitive glue, and then expose it through a UV light source. During the
exposure process, the light transmitted through the transparent part of the negative will
cause the photosensitive glue to undergo photopolymerization, while the photosensitive
glue corresponding to the black (light-shielding) part of the negative will not react.
Development: After the exposure is completed, rinse the screen with clean water. The
photosensitive glue in the unexposed part will be dissolved and washed away, forming a
hollow part on the screen that is consistent with the logo pattern. These hollow parts are
the channels through which the ink will pass.
Drying and curing: Dry the developed screen to completely cure the photosensitive glue,
improve the wear resistance and water resistance of the screen, so that it can withstand
the pressure of the ink and the scraping of the scraper during the printing process, and
ensure the stability and clarity of the pattern.
After the above steps of opening the screen, you will get a screen that can be used for
logo printing. When printing, pour the ink on the screen, and through the extrusion of the
scraper, the ink is transferred to the substrate through the pattern on the screen, thus
completing the printing of the logo

What is the difference between thermal transfer and silk screen printing?

admin — Thu, 26 Jun 2025 13:31:22 +0000

Thermal transfer and silk screen printing are two common printing technologies. They
have some differences in principle, applicable materials, color performance, cost, etc. The
following is a detailed introduction:
– **Printing principle**
– **Thermal transfer**: The ink of the text, pattern, etc. on the transfer paper is sublimated
to the cloth or other materials through high temperature and high pressure. Thermal
transfer is divided into sublimation thermal transfer and thermosetting ink transfer.
Sublimation thermal transfer uses the characteristics of ink sublimation at high
temperature to transfer the pattern to the substrate; thermosetting ink transfer uses heat
pressure to make the ink firmly adhere to the surface of the substrate.
– **Silk screen printing**: Through the extrusion of the scraper, the ink is transferred to the
substrate through the mesh of the printing plate to form the same image and text as the
original. Silk screen printing belongs to hole printing. The image and text part on the
printing plate is the through hole that can pass through the ink, while the non-image and
text part is the blocked hole that cannot pass through the ink.
– **Applicable materials**
– **Thermal transfer**: Commonly used for clothing, textiles, ceramics, metals, plastics
and other materials. For some fabrics that require high color saturation and precision,
such as synthetic fiber fabrics such as polyester and nylon, thermal transfer has a better
effect.
– **Silk screen printing**: Widely used in a variety of materials such as paper, plastic,
glass, metal, leather, etc. It can also be printed well on some rough surfaces or irregularly
shaped objects, such as glass bottles, cans, etc.
– **Color performance**
– **Thermal transfer**: Rich colors, natural transitions, high-precision pattern printing, and
photo-level effects. Especially in the performance of gradient colors and fine patterns, it
has obvious advantages.
– **Silk screen printing**: Bright colors and high saturation, but relatively weak in the
performance of fine patterns and gradient effects. However, through some special silk
screen processes, such as dot printing, the color transition effect can also be improved to
a certain extent.
– **Printing cost**
– **Thermal transfer**: The initial equipment investment is high, and professional
equipment such as thermal transfer machines are required, and the cost of consumables
such as transfer paper and ink is also relatively high. However, for mass-produced
products, due to their high printing efficiency, the unit cost will gradually decrease.
– **Screen printing**: The cost of equipment and consumables is relatively low, the
production cost of the screen is not high, and the price of ink is relatively cheap. However,
screen printing requires more manual operations during the printing process. For complex
patterns or high-precision printing requirements, multiple overprints may be required, and
the labor cost and time cost will increase.
– **Environmental performance**
– **Thermal transfer**: It is relatively environmentally friendly, especially sublimation
thermal transfer, which produces less pollutants such as waste gas and wastewater
during the printing process. However, thermosetting ink transfer may use some inks
containing volatile organic compounds (VOCs), which have a certain impact on the
environment.
– **Screen printing**: Traditional screen printing inks often contain a large amount of
VOCs, which will evaporate into the air during the printing process, causing certain harm
to the environment and human health. However, with the improvement of environmental
awareness, more and more environmentally friendly screen printing inks are now
appearing, such as water-based inks, UV inks, etc., which can effectively reduce pollution.

What is REACH certification？

admin — Thu, 26 Jun 2025 13:28:52 +0000

REACH certification is an important EU regulatory certification on the registration,
evaluation, authorization and restriction of chemicals, which aims to ensure a high level of
protection for human health and the environment, while promoting the competitiveness of
the EU chemical industry. The following is a detailed introduction:
Regulatory content
– **Registration**: For chemical substances with an annual production or import volume of
more than 1 ton, enterprises must register with the European Chemicals Agency (ECHA)
of the EU and provide relevant information about the chemical substance, including
physicochemical properties, toxicological data, use and safety information, etc.
– **Evaluation**: ECHA will evaluate registered chemical substances, review whether the
information submitted by the enterprise is complete and compliant, and evaluate the
potential risks of chemical substances to determine whether further testing or risk
management measures are needed.
– **Authorization**: For chemical substances with high-concern properties, such as
carcinogenic, teratogenic, reproductive toxic substances (CMR), and persistent,
bioaccumulative and toxic substances (PBT), if enterprises want to continue to use them,
they need to apply for authorization from ECHA.
– **Restriction**: Restrict the use of certain chemical substances in specific purposes or
products, and stipulate their maximum allowable content or conditions of use, etc., to
prevent these chemical substances from causing harm to human health and the
environment.
### Certification process
– **Preparation phase**: The enterprise determines the scope of products that need
REACH certification and collects relevant information on chemical substances in the
products, including composition, content, use and safety data. If the enterprise itself
cannot provide complete information, it may need to entrust a professional testing agency
to conduct analysis and testing.
– **Registration phase**: Through the REACH-specific registration platform, the enterprise
submits the prepared information to ECHA. The registration content includes basic
information of chemical substances, safety data sheets (SDS), registration dossiers, etc.
ECHA will conduct a formal review of the submitted registration information. If the
information is incomplete or does not meet the requirements, it will notify the enterprise to
supplement or amend it.
– **Evaluation phase**: ECHA evaluates chemical substances based on registration
information and relevant regulatory requirements. The evaluation may include reviewing
the data submitted by the enterprise, requiring the enterprise to provide additional test
data or information, and risk assessment of chemical substances. Enterprises need to
actively cooperate with ECHA’s evaluation work and provide the required information and
data on time.
– **Authorization or restriction stage**: If a chemical substance is a substance of very high
concern that requires authorization, the enterprise shall gradually reduce the use of the
substance in accordance with the requirements of the REACH regulations before
obtaining authorization, and stop using it within the prescribed period, unless authorized
by ECHA. For restricted chemical substances, enterprises must ensure that the products
meet the restrictions, otherwise they shall not produce, sell or use the relevant products.
### Scope of application
REACH certification applies to chemical substances, preparations and articles produced,
imported or used in the EU market. Specifically, it includes many product areas such as
chemical raw materials, plastics, rubber, textiles, electronic and electrical products, toys,
cosmetics, etc.
### Significance
– **Protect human health and the environment**: Through strict management of chemicals,
REACH certification helps reduce exposure to harmful chemicals to the human body and
pollution to the environment, and reduces potential health risks and ecological hazards.
– **Promote corporate competitiveness**: Although REACH certification places high
demands on enterprises, it also prompts enterprises to strengthen chemical management,
promote technological innovation and green chemistry development, and help improve
the competitiveness of enterprises in the international market.
– **Unified EU market regulations**: REACH certification provides a unified regulatory
framework for chemical management within the EU, eliminates differences in chemical
regulations among member states, and promotes the integration and smooth operation of
the EU’s internal chemical market

What is FINA certification

admin — Thu, 26 Jun 2025 12:51:16 +0000

Fina International Swimming Federation certification refers to the recognition and
standardization of swimming related products and events by the International Swimming
Federation (F é d é ration Internationale de Nation). The following is a detailed
introduction about its certification:
Product Certification
Certification scope: mainly for various equipment used in swimming competitions, such as
swimsuits, goggles, swim caps, etc. Taking swimsuits as an example, Fina certification
aims to ensure that the design, materials, and performance of swimsuits meet certain
standards to ensure fairness and safety in competitions.
Certification standards: Fina’s certification standards for swimwear include multiple
aspects. In terms of material, swimsuit fabrics are required to have good waterproof,
breathable, and elastic properties, while also meeting environmental protection
requirements. In terms of design, the coverage area, thickness, and seams of the
swimsuit are specified to avoid athletes gaining unfair advantages through the swimsuit.
For example, swimsuits cannot provide excessive buoyancy or compression to avoid
affecting the athlete’s natural swimming ability. Through rigorous testing and evaluation,
only swimsuits that meet these standards can obtain Fina certification, allowing athletes to
use them in Fina approved competitions.
Event Certification
Certification content: Fina’s certification of swimming events covers multiple aspects such
as event organization, facilities, and referee teams. Fina has clear specifications for the
venues hosting events, including the length, width, depth, and water quality of the
swimming pool. For example, the standard Olympic swimming pool should be 50 meters
long, 25 meters wide, with a depth of no less than 2 meters, and the water temperature
should be maintained between 25-28 degrees Celsius. At the same time, the organizers of
the event need to have comprehensive competition organization capabilities, including
developing reasonable competition schedules, arranging professional referee teams, and
providing good athlete services.
Certification process: The event sponsor needs to submit detailed application materials to
Fina, including relevant data on venue facilities, event organization plans, referee team
qualifications, and other information. Fina will review these materials and may dispatch
professional personnel for on-site inspections. Only when all conditions meet Fina’s
requirements can the event be certified and become an official event recognized by Fina.
This certification ensures that swimming events worldwide can be conducted under
unified standards, ensuring the fairness and professionalism of the competition, and
enabling athletes from different countries to compete in a relatively consistent
environment when participating in different events.
Fina International Swimming Federation certification has authoritative and extensive
influence in the field of swimming, playing an important role in promoting the development
of global swimming, ensuring fairness and impartiality in competitions, and promoting the
standardization and normalization of swimming equipment.

What is the UKCA certificate?

admin — Thu, 26 Jun 2025 12:41:48 +0000

UKCA is the abbreviation of UK Conformity Assessed, which is a new product certification
launched after Brexit. It applies to goods sold in the markets of England, Wales and
Scotland, with the aim of ensuring that goods sold in the UK market comply with UK laws,
regulations and safety standards. The following is a detailed introduction to UKCA:
Scope of application: including toy safety, electronic appliances, measuring instruments,
machinery, pressure equipment, personal protection equipment, radio equipment, simple
pressure vessels and many other product areas.
Significance:
Compliance requirements: It is an important way to ensure that products comply with
relevant UK laws and safety standards. Certification can improve product compliance.
Product market access: It is a necessary condition for products to enter the UK market.
Uncertified products cannot be legally sold or circulated in England, Wales and Scotland.
Trust and reliability: The certification mark conveys product compliance and safety
information to consumers, represents the recognition of product safety and compliance,
and allows consumers to buy with more confidence.
Legal liability and risk reduction: Through certification, companies assume full legal
responsibility for product compliance and safety, which helps reduce legal risks. If the
product is not certified and there are safety problems or compliance violations, the
company may face legal proceedings, fines or market penalties.
Enhanced competitiveness: Obtaining certification can enhance the competitiveness of
enterprises in international trade, provide conditions for opening up the UK market, and
expand business scope and customer groups.
Certification process: usually includes applicants filling out application forms, providing
product pictures and material lists, determining the directives and coordinated standards
that the product complies with; clarifying the detailed requirements that the product should
comply with; determining test samples; testing the product and verifying its compliance;
drafting and maintaining technical documents required by the directive; after the test is
passed, completing the report, issuing the UKCA certification report, affixing the UKCA
mark, and making a declaration of conformity.
It should be noted that UKCA certification has certain connections and differences with EU
CE certification. After Brexit, the UKCA mark gradually replaced the use of the EU CE
mark in the UK market. For manufacturers who currently hold CE certificates issued by a
notified body, there are different certification transition arrangements for a certain period
of time.
