PAHs, PAHs detected center. PAHs test items

PAHs, PAHs detected center. PAHs detected items PAHs (Polycyclic Aromatic Hydrocarbons, polycyclic aromatic hydrocarbons), is linear ranging from two to seven consisting of benzene, angular or chemical structure of a slug. Mainly due to the incomplete combustion of carbon-containing compound or during use of fossil fuels produced. At present, more than 100 kinds of PAHs known more, and by the US Environmental Protection Agency listed regulated PAHs, there are 16 kinds: Naphthalene Naphthalene, Acenaphthylene acenaphthylene, Acenaphthene acenaphthene, Fluorene Fluorene, Phenanthrene phenanthrene, Anthracene anthracene, Fluoranthene Fluoranthene, Pyrene pyrene, Benzo (a) anthracene Benzo (a) anthracene, Chrysene flexor, Benzo (b) fluoranthene Benzo (b) fluoranthene, Benzo (k) fluoranthene Benzo (k) fluoranthene, Benzo (a) pyrene Benzo (a) pyrene, Indeno (1,2,3-cd) pyrene indene benzene (1,2,3-cd) pyrene, Dibenzo (a, h) anthracene dibenzo (a, n) anthracene, Benzo (g, hi) perylene Benzo (ghi) perylene (perylene). In view of polycyclic aromatic hydrocarbons (PAHs) harm to humans and animals and plants, the German Security Technology Certification Center (ZLS) Experience Exchange Office (Central Experience Exchange Office, ZEK) AtAV Committee requested the GS mark certification mandatory membership of PAHs test (see ZLS official SFAS No. 01-08 ZEK document on the site), this provision was in 2008 to take effect April 1, all the GS mark certification bodies require additional surveying 16 PAHs substances. November 29, 2011, GS certification mandatory two new PAHs test substance, the test standard for ZEK01.4-08, beginning with effect from July 1, 2012. GS mark limit for PAHs requirements are divided into three categories: If the test result is greater than a second-class category, but in line with the limits, should be subject to and in accordance with DIN EN1186 §64LFBG80.30-1 migration tests to confirm the test results. For the following materials and components shall be PAHs GS certification tests: (1) All materials with a strong rubber or naphthalene (mothballs) must accept PAHs smell test: the smell of volatile PAHs mainly containing naphthalene and methylnaphthalene cause. However, if no such odor components or raw materials, it may also contain low volatile PAHs; (2) all soft polymer materials (plastics and rubber materials) and a black could come into contact with the skin or dark hard polymeric materials - such as switches, keyboards, latches, handles and housing material - must accept PAHs test; (3) paint and anti-corrosion materials (naphthalene and methyl naphthalene): they will increase the concentration of PAHs material surface; (4) there is no smell, and have to use other tools in contact with the inner material can not accept PAHs tested. In addition to the German GS certification, EU REACH legislation limiting portion, German food and commodities law also made a restriction on PAHs. REACH regulations restricting portion control for the PAHs from the original EU 76/769 / EEC of amending Directive 2005/69 / EC, 76/769 / EEC and its amendments Directive are in May 31, 2009 abolished all controls all terms incorporate part of REACH restrictions. Part of REACH restriction limits for PAHs requirements: add oil on the market or used in the manufacture of tires add oil shall comply with: (5) BaP content of less than 1 mg / kg (6) 8 种 PAHs (BaP, BeP, BaA, CHR, BbFA, BjFA, BkFA, DBAhA) the total content of less than 10 mg / kg German Food and Commodities Act (Lebensmittel und Bedarfsgegenstandegesetz-LFGB) (German Food Commodity and Feed Law) Section 30 developed PAHs allowable limit Found: detection limit is 0.1 mg / kg, if the material is detected less than 0.1 mg / kg, is considered ND (not detected), (GS Mark quantitation limit of 0.2 mg / kg). North test detection (NTEK) equipped with a full range of advanced detection equipment PAHs, can provide you with the GS certification requirements, the German Food and Commodities Act requirements and the requirements of the EU REACH Regulation PAHs testing services.
