PAHs test
In view of polycyclic aromatic hydrocarbons (PAHs) the harm to humans and animals and plants, the German Security Technology Certification Center (ZLS) Experience Exchange Office (Central Experience Exchange Office, ZEK) AtAV Committee requests that the GS mark certification mandatory membership of the PAHs tested. Other countries also act by written law or a restriction of PAHs, such as: EU 76/769/EEC; U.S. EPA; Chinese GB, GB / T, GHZ.


German Security Technology Certification Center (ZLS) Experience Exchange Office (Central Experience Exchange Office, ZEK) AtAV Committee November 20, 2007 meeting by the formula (see the announcement on the official website ZLS first document ZEK 01-08), requiring the GS mark certification mandatory membership of the PAHs tested, the requirement was in 2008 entered into force on April 1, when all the GS mark certification body will begin to add items measured PAHs.

PAHs Profile
PAHs (Polycyclic Aromatic Hydrocarbons, polycyclic aromatic hydrocarbons), ranging from two to seven benzene rings are composed of linear, angular, or a group-like chemical structures. Mainly due to incomplete combustion of carbon-containing compounds or the use of fossil fuels generated in the process. PAHs are known more than 100 species, while the U.S. Environmental Protection Agency PAHs are regulated out of 16 species (see below):
    ■ Naphthalene Naphthalene ■ Benzo (a) anthracene Benzo (a) anthracene
    ■ Acenaphthylene Acenaphthylene ■ Chrysene Qu
    ■ Acenaphthene Acenaphthylene ■ Benzo (b) fluoranthene benzo (b) fluoranthene
    ■ Fluorene Fluorene ■ Benzo (k) fluoranthene benzo (k) fluoranthene
    ■ Phenanthrene Philippines ■ Benzo (a) pyrene Benzo (a) pyrene
    ■ Anthracene Anthracene ■ Indeno (1,2,3-cd) pyrene indeno benzene (1,2,3-cd) pyrene
    ■ Fluoranthene Fluoranthene ■ Dibenzo (a, h) anthracene Dibenzo (a, n) anthracene
    ■ Pyrene Pyrene ■ Benzo (g, hi) perylene benzo (ghi) North (perylene)


Germany GS Mark certification mandatory testing PAHs
Although PAHs testing only had to follow a voluntary basis, not included in the GS certification requirements, but there had been two German auto-related recall of events: First, the grinding machine wires, chassis and handle such substances were found; one hammer non-slip plastic layer found high concentrations of PAHs compounds. In addition, a Chinese manufacturer of electric tools worth $ 80 million of goods were found to contain PAHs Zengyin been detained in Germany can not enter the port. After the formal implementation of the new rules, products can not be tested PAHs GS certification mark will not get into Germany and smooth.

The following materials and components for the GS certification of PAHs should be tested
    ■ all with a strong rubber or naphthalene (mothballs) the material must accept PAHs smell test: the odor of volatile polycyclic aromatic hydrocarbons mainly containing naphthalene and methyl naphthalene causes. However, if the parts or raw materials no such smell, it may also contain low volatile polycyclic aromatic hydrocarbons;
    ■ All soft polymer materials (plastics and rubber materials) and contact with the skin may be black or dark rigid polymer materials - such as switches, keyboards, latches, handles and casing materials - must accept the PAHs tested;
    ■ paint and corrosion materials (naphthalene and methyl naphthalene): they will increase the surface concentration of polycyclic aromatic hydrocarbons;
    ■ there is no odor, and other tools to be in contact with material can not accept the PAHs within the test.

Limits for PAHs
Consumer goods (food contact materials, the materials will be placed in the mouth, toys and child care products) limits of PAHs in the following:

Three parameters of a class II
And food contact materials or children under the age of 3 will be placed in the mouth and skin contact with regular toy parts, contact for more than 30 seconds, not covered in Category 1, the occasional sex toy parts in contact with the skin contact time less 30 seconds, or no contact with the skin parts
BaPmg / kg not detected (<0.2) * 1 20
The sum of 16 PAHs mg / kg not detected (<0.2) * 10200

If the test result is greater than a class II but in line with the limits need to be based on DIN EN 1186 and § 64 LFBG 80.30-1 migration test to test to confirm the test results.

About the German GS certification
GS certification to the German Product Safety Law, based on uniform standards in accordance with the EU or the German industrial standard DIN EN testing of a voluntary certification, the European market recognized safety certification mark in Germany. GS mark indicates that the use of the product has passed safety tests the credibility of an independent body. GS mark, although not legally required, but it does to product failure caused by an accident, the manufacturer subject to strict German product safety laws. So the GS mark is a powerful marketing tool that can enhance customer confidence and desire to buy.
While the GS is German standards, but most European countries agree. GS certification and meet at the same time, the product will meet the European CE mark requirements. GS mark is not legally required, but because of security awareness has penetrated the general consumer, a GS mark of electrical products in the market will be greater than the average competitive.

PAHs and other laws and regulations restrict
German Food and Commodities Act (Lebensmittel und Bedarfsgegenstandegesetz-LFGB) (German Food Commodity and Feed Law) Section 30 of the PAHs can be established allowable limits:
Parameters of plastic, regular contact with fixed parts, which will be more than 30 seconds contact time of components (such as handles, steering wheel, etc.) plastics, occasional exposure to the components that contact time of less than 30 seconds of parts
BaP 1mg/kg 20mg/kg
16 PAHs sum of 10mg/kg 200mg/kg

Detection limit of 0.1 mg / kg, if the material has been detected less than 0.1 mg / kg, is considered as ND (not detected), (GS Mark quantitative limit of 0.2 mg / kg).

EU Directive 2005/69/EC polycyclic aromatic hydrocarbons
European Parliament and EU member on November 16, 2005 in Strasbourg, France signed the directive 2005/69/EC of polycyclic aromatic hydrocarbons, is the twenty-seventh amendment of Directive 76/769/EEC, and in 2010 January 1, come into effect. EU Directive 2005/69/EC on the market to add oil or add oil for the manufacture of tires should be consistent with:
    ■ BaP content of less than 1 mg / kg
    ■ 8 种 PAHs (BaP, BeP, BaA, CHR, BbFA, BjFA, BkFA, DBAhA) the total content of less than 10 mg / kg
