This document specifies a test method for the determination of the air-purification performance, with regards to the removal of toluene, of materials that contain a photocatalyst or have photocatalytic films on the surface, usually made from semiconducting metal oxides such as titanium dioxide or other ceramic materials, by continuous exposure of a test piece to the model air pollutant under…

This document specifies the minimum technical requirements and performance characteristics for the detection of molecular nucleic acid (DNA or RNA) sequences of specific microorganisms present in water using molecular detection methods based on polymerase chain reaction (PCR). This includes guidelines for validation of PCR related methods (inclusivity, exclusivity, specificity, limits of…

This international standard focuses on the presentation of lexicographic articles in language dictionaries, either monolingual, bilingual or multilingual, following a lexicographic lemma-oriented approach, being addressed for human end-users. Concerning the modelling of the underlying data, the ISO 1951:2007 follows the ISO 24613 series. The document provides recommendations to deal with the…

This document specifies a basic method of determining the particle size distribution applicable to a wide range of mineral soil materials, including the mineral fraction of organic soils. It also offers procedures to deal with the less common soils mentioned in the introduction. This document has been developed largely for use in the field of environmental science, and its use in geotechnical…
