This standard 22/30405909 DC BS EN 17844. Construction products: Assessment of release of dangerous substances. Determination of the content of polycyclic aromatic hydrocarbons (PAH) and of benzene, toluene, ethylbenzene and xylenes (BTEX). Gas chromatographic method with mass spectrometric detection is classified in these ICS categories:

• 91.100.01 Construction materials in general

This document describes two methods for determining the content of polycyclic aromatic hydrocarbons (PAH) and one method for determining the content of benzene, toluene, ethylbenzene and xylenes (BTEX) with gas chromatography with mass spectrometric detection (GC-MS). See Annex A for a list of PAH and BTEX that can be determined with this document. This document is intended to be used for construction products. In a number of cases additional analysis with high performance liquid chromatography (HPLC) can be necessary to determine a number of compounds. To determine PAH multiple liquid-liquid extraction is used to remove disturbing compounds. The tests that led to this document were carried out on different types of roofing material, asphalt and one tar containing asphalt, [3] and [5]. The detectability limit of the methods for individual compounds in roofing material, asphalt and tar containing asphalt for PAH is 0,5 mg/kg to 1,5 mg/kg and for BTEX 0,1 mg/kg.
