This standard 22/30444876 DC BS EN 17331. Construction products: Assessment of release of dangerous substances. Content of organic substances. Methods for extraction and analysis is classified in these ICS categories:

• 91.100.01 Construction materials in general

This document specifies existing methods for the determination of the content of specific organic substances in construction products. The following parameters are covered: BTEX, biocides, dioxins, furans and dioxin-like PCBs, mineral oil, nonylphenols, PAH, PCB, PCP, PBDE, and short-chain chlorinated paraffins. NOTE 1 Methods still under development or available at national level only are listed in Annex B for PFOS, PFOA, HBCD and EOX. The methods can be included in the normative text as soon as full EN standards are available. NOTE 2 Methods that have not been validated for construction products, because no suitable material was available at the time of the robustness validation, only are listed in Annex B. This applies to organotin compounds, phenols and phthalates. The methods listed in this document come from different fields and are expected to be suitable for organic substances in organic extracts from all types of constructions products. The methods in this document are validated for the product types listed in Annex A. NOTE 3 Construction products include, e.g. mineral-based products, bituminous products, wood-based products, polymer-based products and metals. This document includes analytical methods for all matrices except metals.
