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 [1]) and additional PAHs as listed in Table A.2.

Analysis of other PAHs is possible in principle, but sufficient quality assurance performed by the user is necessary to secure the analysis.

The application range for this method is from approximately 4 mg/kg to approximately 15 mg/kg for the eight individual PAHs and from approximately 0,5 mg/kg to approximately 2 mg/ kg for BaP.

NOTE 1 The intended working range for this method is in the 0,1 mg/kg to 15 mg/kg range. For the lower levels precision has not yet been established.
