L'ISO 14532:2014 a pour objet de donner les définitions, symboles et abréviations utilisés dans le domaine du gaz naturel.
Les termes et définitions ont été étudiés et revus de manière à couvrir toutes les acceptations particulières des termes provenant également d'autres sources telles que les normes européennes du CEN (Comité Européen de Normalisation), les normes nationales et les…
Urine-absorbing products for incontinence — Measurement of airborne respirable polyacrylate superabs...
ISO 17191:2004 specifies a method for the determination of polyacrylate (PA) superabsorbent powders in airborne dust by measurement of sodium (Na) by atomic absorption spectrometry (AAS). PA dust samples are collected in polystyrene acrylonitrile air-monitoring cassettes with polytetrafluoroethylene filters and porous plastic backing pads.
This method is applicable to the determination of…
This document specifies the basic dimensions and tolerances, in millimetres of trombone head punches.
This document gives examples of materials and their hardness, and specifies the designation of punches in accordance with this document.
These punches are available with shank diameters, D, from 4 mm to 20 mm.
The main use of the punches specified in this document is for punching holes in steel…
Fans — Determination of fan sound power levels under standardized laboratory conditions — Part 2: Re...
ISO 13347-2:2004 gives a detailed description of reverberant room methods for the determination of fan sound power levels. It is for use under standardized laboratory conditions and recognises that tests in situ are subject to increased uncertainty. These test procedures are not necessarily appropriate to site test conditions. Acoustic system effects are presently the subject of considerable…
Ventilateurs — Détermination des niveaux de puissance acoustique des ventilateurs dans des condition...
L'ISO 13347-2:2004 établit une description détaillée des méthodes en salle réverbérante pour la détermination des niveaux de puissance acoustique des ventilateurs. Elle est destinée à une utilisation dans des conditions de laboratoire normalisées, étant entendu que les essais sur site sont sujets à une incertitude accrue. Un tel mode opératoire d'essai n'est pas nécessairement…
Explosive atmospheres — Part 38: Equipment and components in explosive atmospheres in underground mi...
ISO/IEC 80079-38:2016 is published as a dual logo standard and specifies the explosion protection requirements for the design, construction, assessment and information for use (maintenance, repair, marking) of equipment that may be an individual item or form an assembly. This includes machinery and components for use in mines susceptible to explosive atmospheres of firedamp and/or combustible…
Rubber compounding ingredients — Carbon black — Determination of aggregate size distribution by disc...
ISO 15825:2017 specifies a method for determining the size distribution of carbon black aggregates, using a disc centrifuge photosedimentometer. This technique is based on the hydrodynamic behaviour of carbon black in a centrifugal field. The determination of the aggregate size distribution is important in the evaluation of carbon black used in the rubber industry.
