8. Scope This European Standard specifies a method for quantitative determination of 16 polycyclic aromatic hydrocarbons (PAH) (see Table ) in soil, sludge, sediment, treated biowaste, and waste, using GC-MS and HPLC-UV-DAD/FLD covering a wide range of PAH contamination levels (see Table 2). When using fluorescence detection, acenaphthylene cannot be measured. Table —Target analytes of this European Standard Target analyte CAS-RNa Naphthalene 91–20–3 Acenaphthene 83–32–9 Acenaphthylene 208–96–8 Fluorene 86–73–7 Anthracene 120–12–7 Phenanthrene 85–01–8 Fluoranthene 206–44–0 Pyrene 129–00–0 Benz[a]anthracene 56–55–3 Chrysene 218–01–9 Benzo[b]fluoranthene 205–99–2 Benzo[k]fluoranthene 207–08–9 Benzo[a]pyrene 50–32–8 Indeno[1,2,3-cd]pyrene 193–39–5 Dibenz[a,h]anthracene 53–70–3 Benzo[ghi]perylene 191–24–2 a CAS-RN Chemical Abstracts Service Registry Number. The limit of detection depends on the determinants, the equipment used, the quality of chemicals used for the extraction of the sample and the clean-up of the extract Under the conditions specified in this European Standard, lower limit of application from 10 μg/kg (expressed as dry matter) for soils, sludge and biowaste to 100 μg/kg (expressed as dry matter) for solid waste can be achieved. For some specific samples (e.g. bitumen) the limit of 100 μg/kg cannot be reached. Sludge, waste and treated biowaste may differ in properties as well as in the expected contamination levels of PAH and presence of interfering substances. These differences make it impossible to describe one general procedure. This European Standard contains decision tables based on the properties of the sample and the extraction and clean-up procedure to be used. The method may be applied to the analysis of other PAH not specified in the scope, provided suitability is proven by proper in-house validation experiments.

This document references existing quality and test methodologies for recycled PVC to be used in PVC-U profiles for windows and doors. It contains a description of the controlled loop as such, the definition of those material transformation steps which are relevant for product quality, in particular recycling input and output and profile manufacturing input and output. Traceability tools are specified to characterize this loop as a controlled loop. With regard to PVC waste treatment, the present document relates to existing standards such as EN 15343, EN 15346 and EN 15347. With regard to semifinished and/or finished products, it refers to the European Standard PVC-U window profiles (see EN 12608 1) and to the European Standards for windows and doors (see EN 14351 1, EN 14351-2 and EN 16034). The controlled loop treatment of PVC profiles will be aligned to the general understanding of life cycles as outlined in EN 15804.
