ISO/TS 11999-2:2015 describes compatibility for ensembles of firefighters personal protective equipment (PPE) to be used by firefighters, who are at risk of exposure to high levels of heat and/or flame while fighting fires occurring in structures. ISO/TS 11999-2:2015 includes methods for compatibility testing in laboratories and procedures for compatibility testing including the identification of…

ISO 13347-2:2004 gives a detailed description of reverberant room methods for the determination of fan sound power levels. It is for use under standardized laboratory conditions and recognises that tests in situ are subject to increased uncertainty. These test procedures are not necessarily appropriate to site test conditions. Acoustic system effects are presently the subject of considerable…

This international standard is intended to provide a protocol for the interlab validation of methods for the characterization of sludge/biosolids physical properties considered that in most cases fresh sludge samples cannot be circulated to several laboratories in different countries for validation purposes as uncontrolled variations of their characteristics would occur.

This international standard specifies a chemical conditioning procedure for sludge/biosolids thus allowing results obtained in different places and laboratories, and on different times to be compared when selecting type and dosage of a conditioning product at laboratory scale.

ISO 4582:2017 specifies methods to determine changes in colour and other appearance properties, and variations in mechanical or other properties, of plastics that have been exposed to glass-filtered solar radiation, to natural weathering or to simulated solar radiation from a laboratory source. The procedure used to analyse data depends on whether the test used to characterize the materials being…
