Systèmes de ventilation pour les installations nucléaires — Méthodes d’essai in-situ de l’efficacité...
Le domaine d’application de la série ISO 16659 est de fournir différentes méthodes d’essai visant à évaluer l’efficacité des pièges à iode radioactif dans les systèmes de ventilation des installations nucléaires. La série ISO 16659 concerne les pièges à iode contenant un sorbant solide — principalement du charbon actif et imprégné, les sorbants solides pour l’iode les plus communément utilisés…
Textile glass — Chopped-strand and continuous-filament mats — Determination of average thickness, th...
This document specifies a method for the determination of the average thickness, the thickness under load and the recovery after compression of chopped-strand and continuous-filament textile-glass mats.
Acoustics — Objective method for assessing the audibility of tones in noise — Engineering method
This document describes a method for the objective determination of the audibility of tones in environmental noise.
This document is intended to augment the usual method for evaluation on the basis of aural impression, in particular, in cases in which there is no agreement on the degree of the audibility of tones. The method described can be used if the frequency of the tone being evaluated is…
Guidelines for the determination of the long-term strength of geosynthetics for soil reinforcement
This document provides guidelines for the determination of the long-term strength of geosynthetics for soil reinforcement.
This document describes a method of deriving reduction factors for geosynthetic soil-reinforcement materials to account for creep and creep rupture, installation damage and weathering, and chemical and biological degradation. It is intended to provide a link between the test…
Guidance on quality of water for sterilizers, sterilization and washer-disinfectors for health care ...
This document provides guidance on the quality of water for sterilizers, sterilization and washer-disinfectors (WDs) used to process health care products.
This document covers the quality of water used directly for cleaning, thermal and chemical disinfection, rinsing and sterilization, as feedwater for the generation of steam, as a service to a sterilizer or WD, or as a cooling agent.
This…
