Information technology — Portable Operating System Interface (POSIX®) base specifications — Issue 8
ISO/IEC/IEEE 9945:2009 defines a standard operating system interface and environment, including a command interpreter (or "shell"), and common utility programs to support applications portability at the source code level. ISO/IEC/IEEE 9945:2009 is intended to be used by both application developers and system implementers and comprises four major components (each in an associated volume…
Information and documentation — Paper for documents — Requirements for permanence
Specifies the requirements for permanent paper intended for documents given in terms of minimum strength measured by a tear test, minimum content of substance (such as calcium carbonate) that neutralize acid action measured by the alkali reserve, maximum content of easily oxidized material measured by the kappa number, maximum and minimum pH values of a cold water extract of the paper. Is…
Geosynthetics — Determination of dynamic perforation (cone drop test)
ISO 13433:2006 specifies a method to determine the resistance of geosynthetics to penetration by a steel cone dropped from a fixed height. The degree of penetration is an indication of the behaviour of the geosynthetic when sharp stones are dropped on its surface.
The method is generally applicable to geosynthetics. However, the validity of this test for some types of products should be…
Ventilateurs — Tolérances, méthodes de conversion et présentation des données techniques
L'ISO 13348:2007 spécifie les tolérances sur les performances et la présentation des données techniques des ventilateurs industriels de tous types. Elle ne s'applique pas aux ventilateurs conçus uniquement pour le brassage de l'air, tels que ceux utilisés pour les besoins domestiques et analogues (par exemple, ventilateurs plafonniers ou de table, ventilateurs d'extraction,…
Plastics — Polyethylene (PE) — Determination of co-monomer content by solution state 13C-NMR spectro...
This document specifies two methods for the determination of co-monomer contents of polyethylene products by solution state 13C-NMR spectrometry (nuclear magnetic resonance spectrometry):
— Method A: inverse gated decoupling method;
— Method B: insensitive nuclei enhanced by polarization transfer method.
This document is applicable to copolymers of ethylene having a content of other 1-…
Dispositifs UV-C — Information sur la sécurité — Limites admissibles pour l'exposition humaine
L'ISO 15858 :2016 spécifie les prescriptions minimales de sécurité des personnes s'appliquant à l'utilisation des lampes UVC.
Elle est applicable aux systèmes UVC en conduit, aux systèmes UVC d'air supérieur, aux dispositifs UVC de désinfection portables et à tout autre dispositif UVC pouvant entraîner une exposition des personnes aux UVC.
Elle n'est pas applicable aux…
Fans — Tolerances, methods of conversion and technical data presentation
ISO 13348:2007 specifies performance tolerances and the technical data presentation of industrial fans of all types. It does not apply for fans designed solely for low-volume air circulation, such as those used for household or similar purposes (ceiling and table fans, extractor fans, etc.).
ISO 13348:2007 covers the four installation categories defined in ISO 5801: A, free inlet, free outlet; B…
