this standard covers prefabricated structural members manufactured from either untreated timber or timber treated to improve its natural durability

BS EN 50083-7 lays down the basic methods of measurement of the operational characteristics of cable networks having coaxial cable outputs in order to assess the performance of those networks and their performance limits

Soil quality. Parameters for geochemical modelling of leaching and speciation of constituents in soils and materials - Extraction of crystalline iron oxides and hydroxides with dithionite Ingestion-build-73073 definitions and means for understanding1 Scope This part of ISO 12782 specifies the determination of the content of reactive iron in the form of crystralline iron oxides and hydroxides in soil and other materials by extraction with dithionite. Other materials also include waste. The content of reactive iron can be used as input in geochemical models to represent the content of crystalline iron (hydr)oxides. NOTE Although the ammonium oxalate oxalic acid extraction (ISO 127823) is commonly
