Phthalate Testing
The European Commission issued Directive 2005/84/EC on December 14, 2005, which is the 22nd amendment to 76/769/EEC, the purpose of which is to limit the use of phthalates in toys and children's products. The use of this directive took effect on January 16, 2007 and was repealed on May 31, 2009. The corresponding control requirements are included in the REACH Regulations Restrictions (Annex XVII). Due to the wide use of phthalates, many well-known electronics companies have begun to control phthalates in electrical and electronic products.

Halogen Testing
With the increasing awareness of global environmental protection, halogen-containing compounds such as halogen-containing flame retardants, halogen-containing pesticides and ozone layer destroyers will be gradually banned, forming a global trend of halogen-free. The halogen-free circuit board standard IEC61249-2-21:2003 issued by the International Electrotechnical Commission (IEC) in 2003 even upgraded the halogen-free standard from "free of some halogen compounds" to "free of halogen". Subsequently, major international well-known IT companies (such as Apple, DELL, HP, etc.) quickly followed up to formulate their own halogen-free standards and implementation schedules. At present, "halogen-free electrical and electronic products" has formed a broad consensus and become the general trend, but no country has issued halogen-free regulations, and halogen-free standards can be implemented in accordance with IEC61249-2-21 or the requirements of their respective customers.

Organostannic Compound Testing
The European Union issued 89/677/EEC on July 12, 1989, which is the 8th amendment to 76/769/EEC, and the directive stipulates that it cannot be sold on the market as a biocide in freely cross-linked antifouling coatings and its formulation ingredients. On May 28, 2009, the European Union adopted Resolution 2009/425/EC, further restricting the use of organotin compounds. Since June 1, 2009, the restriction requirements of organotin compounds have been included in the control of REACH regulations.
Reach Restriction (original 2009/425/EC) are as follows
| substance | time | Require | restricted use |

From January 1, 2012 |
Dioctyltin compounds with a tin content exceeding 0.1% shall not be used in certain articles |
Items covered: textiles, gloves, child care products, diapers, etc. |
PAHs Testing
In May 2019, the German Product Safety Committee (Der Ausschuss für Produktsicherheit, AfPS) released a new standard for the testing and evaluation of polycyclic aromatic hydrocarbons (PAHs) in GS certification: AfPs GS 2019:01 PAK (the old standard is: AfPS GS 2014: 01 PAK). The new standard will be implemented from July 1, 2020, and the old standard will become invalid at the same time.

Authorization and Restriction of Chemicals REACH
REACH is the abbreviation of EU Regulation 1907/2006/EC (Registration, Evaluation, Authorisation, and Restriction of Chemicals). The Chinese name is "Registration, Evaluation, Authorization and Restriction of Chemicals", which was officially launched on June 1, 2007. effective.
Substances of Very High Concern SVHC:
Substances of very high concern. It is a general term for a large class of hazardous substances under the REACH regulation. SVHC includes a series of highly hazardous substances such as carcinogenic, teratogenic, reproductive toxicity, and bioaccumulation.
Restriction
REACH Article 67(1) requires that substances listed in REACH Annex XVII (by themselves, in mixtures or in articles) shall not be manufactured, placed on the market and used unless restricted conditions are complied with。
Requirements of Restriction
On June 1, 2009, the REACH Restriction List (Annex XVII) came into effect, replacing 76/769/EEC and its multiple amendments. Up to now, the REACH restricted list includes 64 items totaling more than 1,000 substances.
In 2015, the European Union successively published Commission Regulations (EU) No 326/2015, (EU) No 628/2015 and (EU) No1494/2015 in its official gazette, targeting REACH Regulation (1907/2006/EC) Annex XVII ( Restriction List) was revised to update PAHs detection methods, restrictions on lead and its compounds, and limit requirements for benzene in natural gas.
Appendix XVII lists the conditions for restricted use and the restricted content for various restricted substances.
Key points of operation
Accurately understand the restricted areas and conditions for various substances;
Screen out the parts that are closely related to your own industry and products from the huge list of restricted substances;
Based on rich professional experience, screen out high-risk areas that may contain restricted substances;
Restricted substance information investigation in supply chain requires effective delivery tools to ensure accurate information and cost savings.
