defines equipment, methods, and procedures for obtaining laboratory measurements of sound pressure levels radiated by control valves and/or associated piping configurations, including fixed restrictions, through which compressible fluids are passing. Control valves discharging to atmosphere are excluded from this standard

This document provides voluntary performance targets for cookstoves and is intended to supplement ISO 19867-1. These voluntary performance targets are intended for use with the results of the laboratory testing specified in ISO 19867-1. These voluntary performance targets are provided as informative guidance, and are not intended as normative requirements for the testing of cookstoves.…

IEC 62153-4-13:2009(E) details the method of laboratory test to determine the coupling attenuation for links and channels used in analogue and digital communication systems. This publication is to be read in conjunction with IEC 62153-4-5:2006.

1. Scope 1.1 This method determines the degradation of polystyrene foams by measuring mass loss due to a combination of abrasion and impact produced by a laboratory tumbling device. 1.2 The values stated in metric (SI) units are to be regarded as the standard. The values in parentheses are provided for information only. 1.3 This Standard does not purport to address all of the…

This document provides standard procedures for the collection, handling and storage of soil for subsequent biological testing under aerobic conditions in the laboratory. It applies to the collection, handling and storage for assessing the effects of soil on microorganisms, invertebrates (e.g. survival, reproduction, growth, behaviour) and plants (e.g. development, growth). This document is not…

1.1.1 Scope Replacement: This Part 2 is applicable to electrically powered LABORATORY CENTRIFUGES. This group safety publication is primarily intended to be used as a product safety standard for the products mentioned in the scope, but shall also be used by technical committees in the preparation of its publications for products similar to those mentioned in the scope of this standard, in…

ISO/TS 17892-6:2004 specifies the laboratory determination of undrained shear strength of both undisturbed and remoulded specimen of saturated fine grained cohesive soils by use of a fall-cone. This document specifies the fall-cone test, in which a cone is allowed to fall with its tip towards a soil specimen, whereupon the penetration of the cone into the soil is measured. Tests performed…

1 Scope and object This clause of Part 1 is applicable except as follows: 1.1.1 Equipment included in scope Replacement: Replace the text, except the first paragraph, with the following new text: This part of IEC 61010 is applicable to electrically operated laboratory equipment and its accessories for mechanical mixing and stirring, where mechanical energy influences the shape or size or…

Specifies a laboratory mechanical method of test for the determination of the relationship between tangential loading and relative displacement for certain types of vertical joints between large reinforced concrete panels subjected to tangential loading. Is applicable to vertical joints between large wall-panels satisfying certain conditions defined in the standard.
