This document specifies a method for the determination of the bound styrene content of styrene-butadiene rubber (SBR) lattices. The method is applicable to hot (approximately 50 °C) emulsion polymerized SBR lattices having a bound styrene content, expressed on the SBR content, of up to 55 % and to cold (approximately 5 °C) emulsion polymerized SBR lattices having a bound styrene content between…

This document specifies a test method for the determination of the tensile strength of perforated lines of tissue paper. It uses a tensile-testing apparatus operating with a constant rate of elongation. This method is only used for measuring machine-direction tensile strength, that is for cross-direction perforations on tissue paper. The calculation of perforation efficiency is also specified in…

This document defines the primary space debris mitigation requirements applicable to all elements of unmanned systems launched into, or passing through, near-Earth space, including launch vehicle orbital stages, operating spacecraft and any objects released as part of normal operations.

This document establishes the basis for a framework for water utilities to operate efficiently and effectively considering stakeholder needs and expectations. This document is applicable to all water utilities, regardless of ownership and management model (public or private), size, service provided or location. This document proposes principles for effective and efficient corporate governance of…

Le présent document spécifie une méthode d’essai permettant de déterminer la résistance à la rupture par traction des lignes de prédécoupe du papier tissue. Cette méthode implique l’utilisation d’un appareil d’essai de traction fonctionnant à un gradient d’allongement constant. Cette méthode est utilisée uniquement pour mesurer la résistance à la rupture par traction dans le sens machine, c’est-à…

This document specifies safety requirements for transparent welding curtains, strips and screens to be used in workplaces where arc welding is taking place. They are intended to provide protection against harmful levels of optical radiation and spatter for workers who are in the vicinity of arc welding processes but not involved in the welding itself. They are intended to reduce the discomfort…

Le présent document spécifie les prescriptions de sécurité relatives aux rideaux, lanières et écrans de soudage transparents destinés à être utilisés sur les lieux de travail où du soudage à l'arc est réalisé. Ils sont destinés à assurer la protection contre les niveaux nocifs de rayonnement optique et contre les projections, des travailleurs qui se trouvent à proximité des procédés de…

IEC 61967-8:2023 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 61967-8:2023 defines a method for measuring the electromagnetic radiated emission from an integrated circuit (IC…

IEC 62321-3-4:2023 specifies procedures for the screening of di-isobutyl phthalate (DIBP), di-n-butyl phthalate (DBP), benzyl butyl phthalate (BBP), di-(2-ethylhexyl) phthalate (DEHP) in polymers of electrotechnical products by using high performance liquid chromatography with ultraviolet detector (HPLC-UV), thin layer chromatography (TLC) and thermal desorption mass spectrometry (TD-MS). High…

IEC 62321-3-4:2023 spécifie des modes opératoires pour le criblage du phtalate de di-isobutyle (DIBP), du phtalate de di-n-butyle (DBP), du phtalate de benzyle et de butyle (BBP), du phtalate de bis (2-éthylhexyle) (DEHP) dans les polymères de produits électrotechniques en utilisant la chromatographie liquide à haute performance avec détecteur ultraviolet (HPLC-UV), la chromatographie sur couche…
