Le présent document spécifie le dosage du Cr(VI) dans les déchets solides et les sols par digestion alcaline et chromatographie ionique avec détection spectrophotométrique. Cette méthode peut être utilisée pour déterminer les fractions massiques de Cr(VI) dans les solides supérieures à 0,1 mg/kg.
NOTE Il n’est pas possible de consigner une teneur en Cr(VI) valable dans un rapport…
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…
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,…
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…
Data structures for electronic product catalogues for building services — Part 4: Data dictionary st...
The focus of ISO 16757 is the support of manufacturers to provide their product data in electronic product catalogues. The standard - ISO 16757 Part 4: Dictionaries for product catalogues – describes which data structures are required in a dictionary to support the exchange of product data from manufacturers to designers of building services systems.
Basis for this specification are the…
Refrigerated hydrocarbon and non-petroleum based liquefied gaseous fuels — Metering of gas as fuel o...
ISO 19970:2017 specifies minimum requirements to quantify the boil-off gas (BOG) consumed on liquefied natural gas (LNG) carriers for their own functions, notably for power generation, during cargo transfer operations. BOG in this document refers to the low molecular gas returned from shore tanks to ships' tanks and the gas produced in ships' cargo tanks.
ISO 19970:2017 provides…
This document specifies the requirements and test methods for factory-made cellular glass products which are to be used for thermal insulation of buildings. The products are manufactured in the form of slabs, faced or unfaced boards.
This document describes product characteristics and test methods, designation code, marking and labelling.
Products used in prefabricated thermal insulation…
