PAHS (polycyclic aromatic hydrocarbons)

Summary of Certification ContentPAHs, scientific name polycyclic aromatic hydrocarbons. It is a type of harmful substance produced by incomplete combustion or high-temperature treatment of fuels such as petroleum and coal, as well as wood and combustible gases. It usually exists in petrochemical products, rubber, plastics, lubricants, rust preventive oils, incomplete combustion organic compounds, and is one of the important carcinogens in the environment.The European Parliament and the European Commission signed the 2005/69/EC Directive in Strasbourg, France, on November 16, 2005 and issued it on December 9 of the same year. This directive mainly provides instructions for polycyclic aromatic hydrocarbons (PAHs) in tires and added oil.On April 1, 2008, the official resolution ZEK 01-08 of the German Safety Technology Certification Center ZLS (GS authorized agency) stated that GS logo certification will be mandatory to include the requirements of PAHs, and products that do not meet the r...

California 65 Test

Summary of Certification ContentProposition 65, also known as the California Safe Drinking Water and Toxic Enforcement Act, was unanimously passed by an overwhelming majority of California residents in November 1986. This proposal is implemented by the Environmental Health Hazard Assessment Agency (OEHHA) under the California Environmental Protection Agency (Cal/EPA).The proposal stipulates that individuals engaged in trading with 10 or more employees (unless otherwise exempted) must affix clear and reasonable warning labels on products containing chemicals that are known to cause cancer or reproductive toxicity to avoid contact with humans, and must not discharge such chemicals into drinking water. Consumer product warnings can be placed directly on the product label or in a prominent location near the store products.Proposition 65 lists approximately 800 chemicals that have been identified by California authorities as carcinogenic or reproductive toxic.

REACH-SVHC test

The main content of REACH The Impact of REACH System on China's Export Trade1. Wide range of industries affected: In addition to having a direct impact on chemical enterprises, REACH will have an impact on all enterprises producing downstream chemical products, including textiles, electromechanical, toys, furniture, etc., involving over 1 million types of products.2. The export cost of enterprises has greatly increased: according to EU estimates, the basic testing cost for each chemical substance is about 85000 euros, and the testing cost for each new substance is about 570000 euros.3. The required amount of data is large: REACH requires a series of registration archive technical documents such as chemical safety data sheets, safety assessment reports, and risk assessments, which involve a complex and massive amount of data.Introduction to the REACH instructionWhat is REACH - 'Registration, Evaluation, Authorization and Restriction of Chemicals' is a regulation of the ...

Environmental RoHS testing

Summary of Certification ContentIn order to control the pollution of electronic and electrical waste to the ecological environment, in February 2003, the European Union issued the 2002/95/EC directive on January 27, 2003, namely the 'Directive on Prohibiting the Use of Certain Hazardous Substances in Electronic and Electrical Equipment' (referred to as the RoHS directive). This directive stipulates that from July 1, 2006, electronic and electrical products entering the EU market are prohibited from using six categories of hazardous substances. On July 21, 2011, RoHS 2.0, the revised version of the RoHS Directive (2011/65/EU), replaced the old version of the RoHS Directive (2002/95/EC), and EU member states must update RoHS 2.0 to local laws by January 2, 2013.

AZO (azo compound)

Summary of Certification ContentA type of organic compound in which the two ends of an azo group are connected to an aromatic group. Azo dyes are the most diverse type of synthetic dyes, widely used for dyeing and printing various natural and synthetic fibers, as well as for coloring paints, plastics, rubber, etc. Azo dyes can release aromatic amines, some of which are harmful substances. The azo involved in electronic products mainly refers to the fabric and leather used in the product or packaging. In addition, the coloring of paint, plastic, and rubber is also useful.Article 43 and Appendix VIII of REACH Annex 17 list 22 azo dyes, aromatic amines, and limit their use. The limit value is 0.003% (mass ratio of each aromatic amine in the finished product or dyed part). The 2002/61/EC directive is consistent with REACH.In addition, some standards limit 24 aromatic amines.Please note that not all azo fuels are harmful. Currently, only 22 (or 24) are restricted, and the limit is that the ...
