German GS certification of polycyclic aromatic hydrocarbons ( PAHs )

Polycyclic Aromatic Hydrocarbons ( PAHs ) , English name " Polycyclic " , for a total of 100 kinds of chemical structural formula , the European Union in 2005 of Polycyclic Aromatic Hydrocarbons ( PAHs instruction , 200569EC ) , limit comprises ( a ) pyrene ( BaP ) , including 16 kinds of PAHs are used , this instruction is currently defunct , but its provisions regulating substance of PAHs was incorporated into the REACH limit portion . German security authentication technology center experiences . .. . .. . .. . .. . .. . .. . .. . .. . .. . .. . office ( ZLS - ATAV ) as from 1 April 2008 , all GS mark certification agencies plus PAHs measured item .
16 kinds of PAHs , respectively :
