Scope 1.1 This procedure defines the long-term thermal resistance (LTTR) of a foam product as the value measured after 5-year storage in a laboratory environment and provides means for its prediction based on an accelerated laboratory test. 1.2 This procedure, based on ASTM standard test methods ASTM C1303 and ASTM C518, can be applied to a wide range of preformed as well as field…

This document specifies general requirements and guidance for metagenomics-dedicated sample preparation, and generating and analysing metagenomics sequence data obtained from massive parallel sequencing platforms. The specified metagenomics process includes the following stages: a)       sampling strategy and process, including type, storage, transportation, extraction, quality; b)       nucleic…

This document establishes principles for the determination of the acoustic performance of fans. In addition, this document can be used to determine the acoustic performance of fans combined with an ancillary device such as a roof cowl or damper or, where the fan is fitted with a silencer, the sound power resulting from the fan and silencer combination.

This document specifies the general requirements for the in vitro amplification of nucleic acid sequences (DNA or RNA). This includes polymerase chain reaction (PCR)-based methods like quantitative PCR, qualitative PCR, reverse transcription-PCR and digital PCR. The minimum requirements laid down in this document are intended to ensure that comparable and reproducible results are obtained in…

This document specifies a method for the enumeration of intestinal enterococci in water, including Enterococcus faecalis, Enterococcus faecium, Enterococcus durans, Enterococcus avium, Enterococcus gallinarum, Enterococcus hirae, Enterococcus casselifavus. The method is based on the growth of target organisms in a liquid medium and calculation of the “most probable number” (MPN) of microorganisms…

This document specifies a method to measure sound power by using sound intensity measurements on a measurement surface which encloses the sound source. This document provides guidelines on the acoustical environment, ambient noise, measurement surface, and number of measurements. The installation categories are generally designed to represent the physical orientation of a fan installed in…

This document specifies a test method for investigating the oxidative stability of ultra-high-molecular-weight polyethylene (UHMWPE) moulded forms as a function of processing and sterilization method. This document describes a laboratory method for accelerated ageing of specimens taken from UHMWPE moulded forms or forms fabricated from these for use in the manufacture of surgical implants. The…

This document specifies laboratory procedures which are intended to imitate the effects of naturally occurring reactions such as oxidation or hydrolysis by humidity for flexible and rigid cellular polymeric materials.

This document specifies a method of determining the water content of rocks. This document is applicable to the laboratory determination of the water content of a rock test specimen by oven-drying within the scope of geotechnical investigations. The oven-drying method is the definitive procedure used in usual laboratory practice. The practical procedure for determining the water content of a rock…

This document specifies the general conditions and procedures observed when testing coated test specimens by exposing them to constant condensation-water atmospheres or alternating condensation-water atmospheres, in a cabinet with a heated water reservoir. These conditions and procedures ensure that the results of tests carried out in different laboratories are reproducible. This document does…
