ASTM D8143-17

1.1 This test method covers the qualitative and quantitative determination of the EU-8 list of polycyclic aromatic hydrocarbons (PAH) on carbon black. The EU-8 list of PAH compounds is given in Table 1. The procedure involves Soxhlet extraction with toluene followed by extract analysis using gas chromatography with mass spectrometry (GC/MS). This method is not intended to test for U.S. Food and Drug Administration (FDA 21 CFR 178.3297) compliance of carbon blacks used for indirect food contact applications.
