Testing of hazardous substances in electronic and electrical appliances

Limits;

Based on the above-mentioned regulatory standards, some well-known companies have proposed their own halogen-free standards. Currently, the mainstream halogen-free limit standard in the industry is based on IEC 61249-2-21, with the following limits:

Cl < 900 ppm;

Br < 900 ppm;

Cl + Br < 1500 ppm

The main halogen detection methods currently used are EN 14582 and IEC 61189.

8. PFOS (Perfluorooctane Sulfonate) / PFOA (Perfluorooctanoic Acid Ammonium)

PFOS is the abbreviation for perfluorooctane sulfonate. Substances that can decompose into PFOS are called PFOS-related chemicals. PFOS is defined as "a substance that persists in the environment, is bioaccumulating, and is harmful to humans." There is evidence that exposure to perfluorinated chemicals, including PFOS, may cause birth defects, adversely affect the immune system, and damage thyroid function, leading to many developmental problems during pregnancy. In light of the hazards of PFOS, the European Union issued Directive 06/122/EC on December 27, 2006, "Directive on the restriction of the sale and use of perfluorooctane sulfonate (PFOS)". The limits set by this directive are:

Less than 50 ppm in substances and mixtures (such as inks, paints, etc.)

Less than 1000 ppm in articles (including finished products, semi-finished products and their components)

Less than 1 μg/m² in textiles or coating materials

These limits came into effect on June 27, 2008.

This directive was the 30th amendment to Directive 76/769/EEC. Directive 76/769/EEC and all its amendments were repealed on May 31, 2009, and their corresponding control and restriction requirements were all incorporated into the REACH Regulation.

PFOA is short for perfluorooctanoic acid, and its applications include surface treatment of household products (such as non-stick cookware) and packaging for convenience foods. These applications are also suspected of carrying the same hazards as PFOS. The European Parliament has imposed restrictions on PFOA and PFOA salts, requiring a review of hazardous incidents, the search for safer alternatives, and the definition of hazard reduction measures. The dangers of PFOA have also drawn significant attention from the US public and regulatory bodies, leading to its inclusion in California's Proposition 65 list of carcinogens. On June 28, 2013, Norway amended Section 2-32 of the Norwegian Product Act, announcing a national ban on PFOA and its salts and esters in consumer products. The restrictions apply to solid and liquid products, including textiles.
