This document specifies two procedures for the preparation of laboratory sheets prior to measuring optical properties. One is the preparation of pads in a Büchner funnel using a filter paper or a wire screen and the other one is the preparation of laboratory sheets in a standard sheet former (conventional or Rapid Köthen). This document is applicable to all wood pulps and to most other types of…

Le présent document spécifie deux modes opératoires pour la préparation des feuilles de laboratoire préalablement au mesurage des propriétés optiques. L’un consiste à préparer des galettes dans un entonnoir Büchner en utilisant un papier-filtre ou une toile, l'autre à préparer des feuilles de laboratoire dans une formette standard (conventionnelle ou Rapid-Köthen). Le présent document est…

1 Scope This part of ISO/IEC 80079 specifies the basic method and requirements for design, construction, testing and marking of non-electrical Ex equipment, Ex Components, protective systems, devices and assemblies of these products that have their own potential ignition sources and are intended for use in explosive atmospheres. Hand tools and manually operated equipment without energy…

1 Scope This part of ISO/IEC 80079 specifies the requirements for the design and construction of nonelectrical equipment, intended for use in explosive atmospheres, protected by the types of protection constructional safety “c”, control of ignition source “b” and liquid immersion “k”. This part of ISO/IEC 80079 supplements and modifies the requirements in ISO 80079-36. Where a requirement of…

IEC 60115-4:2022(E) relates to resistors having a rated dissipation typically greater than 1 W up to and including 1 000 W for use in electronic equipment. This document is applicable to fixed power resistors with a maximum surface temperature (MET) higher than the preferred upper category temperature (UCT) of 200 °C. NOTE Heat sink resistors, i.e. resistors which in their operation depend on…

IEC 62694:2022 applies to backpack-type radiation detectors (BRDs) that are primarily used for the detection of illicit trafficking of radioactive material. BRDs are portable instruments designed to be worn during use. BRDs detect gamma radiation and may include neutron detection and the ability to identify gamma-ray emitting radionuclides. This document establishes the operational and testing…

This document specifies three methods for the determination of water-soluble chlorides in non-metallic blast-cleaning abrasives, namely, amperometric titration, spectro-photometry and ion chromatography. This document is part of the ISO 11127 series dealing with the sampling and testing of non-metallic abrasives for blast-cleaning. The types of non-metallic abrasive and requirements on each are…

IEC 61196-10:2022 specifies the materials and cable construction for semi-rigid coaxial communication cables with fluoropolymer dielectric, IEC type designation, identification, marking and labelling, standard rating and characteristics, requirements of finished cables, quality assessment, delivery and storage, etc. This part of IEC 61196 applies to semi-rigid coaxial communication cables with…

This document specifies requirements for safety and environmental aspects in relation to operation, maintenance and repair of refrigerating systems and the recovery, reuse and disposal of all types of refrigerant, refrigerant oil, heat transfer fluid, refrigerating system and part thereof. This document does not cover "motor vehicle air conditioners" constructed according to the product…
