Petroleum products. Determination of content of Benzo(a)pyrene (BaP) and selected polycyclic aromatic hydrocarbons (PAH) in extender oils. Procedure using double LC cleaning and GC/MS analysis1 Scope This European Standard specifies a procedure for the determination of the content of benzo[a]pyrene (BaP) in extender oils which are commonly used in the rubber industry for the production of tyres or parts of tyres. The method also yields the sum of the eight individual polycyclic aromatic hydrocarbons (PAHs) listed in Table 1. The procedure has been tested and verified for the PAHs listed in Table 1 (those required by the European Commission
