1 Scope and object This International Standard applies to controllers intended for starting, controlling and stopping stationary fire pumps, including automatic and non-automatic types for alternating current electric motor or diesel engine-driven fire pumps. It is anticipated that a controller only controls a single driver. Controllers for electric motor-driven fire pumps always include…

This document gives the specifications for impact attenuation testing equipment used to evaluate the impact performance characteristics of playground surfacing. Its specifications are aimed at ensuring that developers and manufacturers of such instruments meet minimum performance characteristics to allow repeatable, reproducible and accurate results. This document does not specify a test method.…

This document specifies: — the physical and chemical tests on raw rubbers, and — the standardized materials, a standardized test formulation, equipment, and processing methods for evaluating the vulcanization characteristics of all types of isobutene-isoprene rubber (IIR).

Scope 1.1 These requirements cover stationary engine generator assemblies that are intended for installation and use in ordinary locations in accordance with the following: a) The National Electrical Code, NFPA 70; b) The Canadian Electrical Code, Part I, CSA C22.1; c) The Standard for the Installation and Use of Stationary Combustion Engines and Gas Turbines, NFPA 37; d) Natural Gas and…

Domaine d’application 1.1 Ces exigences portent sur le montage des groupes électrogènes stationnaires qui sont destinés à être installés et utilisés dans des emplacements ordinaires conformément aux codes suivants : a) Code national de l’électricité, NFPA 70; b) Code canadien de l’électricité, première partie, CSA C22.1; c) Standard for the Installation and Use of Stationary Combustion…

IEC 62715-6-3:2020 (E) is to define the standard test methods to evaluate the mechanical robustness of flexible display modules, especially mechanical robustness regarding impact and hardness, which include displays such as liquid crystal displays (LCDs), e-paper, and organic light emitting diode (OLED) displays, against external forces applied to a panel.

IEC 60601-2-21:2020 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 60601-2-21:2020 applies to the BASIC SAFETY and ESSENTIAL PERFORMANCE of INFANT RADIANT WARMERS as defined in…

This document specifies the physical and mechanical properties of pipes made from unplasticized polyamide (PA-U) in accordance with ISO 16486-1, intended to be buried and used for the supply of gaseous fuels. It also specifies the test parameters for the test methods to which it refers. The ISO 16486 series of standards is applicable to PA-U piping systems, the components of which are connected…

IEC 63182-2:2020 specifies the dimensions that are of importance for mechanical interchangeability for a preferred range of ring-cores (also called toroids) made of magnetic powder, the effective parameter values to be used in calculations involving them, and gives guidelines on allowable limits of surface irregularities applicable to coated ring-cores. The selection of core sizes for this…

IEC 60601-2-21:2020 applies to the BASIC SAFETY and ESSENTIAL PERFORMANCE of INFANT RADIANT WARMERS as defined in 201.3.204, also referred to as ME EQUIPMENT. If a clause or subclause is specifically intended to be applicable to ME EQUIPMENT only, or to ME SYSTEMS only, the title and content of that clause or subclause will say so. If that is not the case, the clause or subclause applies both to…
