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 eight individual polycyclic aromatic hydrocarbons (PAHs) listed in Table 1. The intended working range for this method is in the 0,1 mg/kg to 10 mg/kg range.

The method has been tested and verified for the PAHs listed in Table 1 and Table A.2.

NOTE 1 Analysis of other PAHs is possible in principle, but the user should perform sufficient quality assurance to secure the analysis.

NOTE 2 For the purposes of this European Standard, the term "% (m/m)" is used to represent the mass fraction (ω).
