This document specifies a method for determining the ultimate aerobic biodegradability of plastic materials under controlled composting conditions by gravimetric measurement of the amount of carbon dioxide evolved. The method is designed to yield an optimum rate of biodegradation by adjusting the humidity, aeration and temperature of the composting vessel. The method applies to the following…

This document specifies a method for the enumeration of Pseudomonas aeruginosa in water. The method is based on the growth of target organisms in a liquid medium and calculation of the most probable number (MPN) of organisms by reference to MPN tables. This document is applicable to a range of types of water. For example, hospital waters, drinking water and non‑carbonated bottled waters intended…

This document establishes a method for radioactivity measurement and determination of the storage periods of the radioactive wastes produced as a result of the medical application of radioisotopes based on counting measurements using a detector and decay correction of the initial activity concentration of the radioisotopes contained in the waste stream. It provides a set of controls and…

This document specifies the requirements for the laboratory testing of the volume resistivity of specially prepared test pieces of vulcanized or thermoplastic rubber compounds rendered conducting or dissipative by the inclusion of carbon black or ionizable materials. The tests are suitable for materials with a resistivity of less than about 108 Ω⋅m. Method 1 is the preferred method when test…

The quality of a supplier of a dosimetry service depends on both the characteristics of the approved (type‑tested) dosimetry system[1] and the training and experience of the staff, together with the calibration procedures and quality assurance programmes. This document specifies the criteria and the test procedures to be used for the periodic verification of the performance of dosimetry services…

This document provides a framework for the characterization of physical and chemical properties of tyre and road wear particles (TRWP) using published analytical standards. It is applicable to laboratory-generated TRWP and TRWP collected in the environment. NOTE This framework focuses primarily on published ISO standards, but includes standards published by other entities such as ASTM and…

This document specifies methods for measuring rolling resistance, under controlled laboratory conditions, for new pneumatic tyres designed primarily for use on passenger cars, trucks and buses. This document is not applicable to tyres intended for temporary use only. It includes a method for correlating measurement results to allow inter-laboratory comparisons. It is designed to facilitate…

This document specifies methods of test and minimum performance requirements for personal protective clothing, designed to protect the wearer's body, except for the head, hands, and feet, that is worn during wildland firefighting and associated activities. This clothing is not intended to provide protection during fire entrapment. This document covers the general design of the garment, the…

This document specifies a method for the generation of tyre and road wear particles (TRWP) in a road simulator laboratory that is representative of actual driving conditions. Guidance is provided for the road simulator system, test pavement and tyres, vacuum collection system, monitoring, and reporting. This method is applicable for the collection of TRWP from a known pavement and tyre type under…

This document specifies a procedure for the verification of portable power measurement equipment using a strain gauge in the laboratory. The power measurement equipment verified in accordance with this document can be used on merchant ships.
