This document specifies a method for the calibration of reference blocks to be used for the indirect and daily verification of Rockwell hardness testing machines and indenters, as specified in ISO 6508-2. This document also specifies requirements for Rockwell machines and indenters used for calibrating reference blocks and specifies methods for their calibration and verification. Attention is…

This document specifies the method for Rockwell regular and Rockwell superficial hardness tests for scales A, B, C, D, E, F, G, H, K, 15N, 30N, 45N, 15T, 30T, and 45T for metallic materials and is applicable to stationary and portable hardness testing machines. For specific materials and/or products, other specific International Standards apply (e.g. ISO 3738-1 and ISO 4498).

This document specifies two separate methods of verification of testing machines (direct and indirect) for determining Rockwell hardness in accordance with ISO 6508-1, together with a method for verifying Rockwell hardness indenters. The direct verification method is used to determine whether the main parameters associated with the machine function, such as applied force, depth measurement, and…

This document specifies a laboratory test method for measuring perceived air quality using human subjects that can be used for assessing the performance of air cleaners removing gas-phase pollutants. The method describes the performance of gas-phase air cleaners with respect to removal of pollutants that can be sensed by human subjects. The method has a reference to sensory tests specified in ISO…

This document gives the terminology and basic concepts of association, including objective functions and association constraints and material offset. This document is not intended to specify association defaults and GPS syntax which are introduced in other (ISO GPS) International Standards. NOTE            The association can be used to establish for example: —      a datum; —      a reference…

Le présent document fournit la terminologie et les concepts de base de l’association, incluant les fonctions objectifs et les contraintes d’association, ainsi que l’offset matière. Le présent document n’est pas destiné à spécifier les paramètres par défaut des associations et la syntaxe GPS, qui sont introduits dans d’autres normes internationales (ISO GPS). NOTE            L’association peut…

This document specifies the test methods for representative samples of the equipment and the minimum accuracy criteria applicable to verifiers using the methodologies of ISO/IEC 15415 for multi-row bar code symbols and two-dimensional matrix symbologies. This document also specifies reference calibration standards for verifier conformance. NOTE       ISO/IEC 15426-1 applies to verifiers for…

This document specifies a set of tests and procedures designed to indicate whether encoders or decoders meet the requirements specified in ISO/IEC 23090-5.

IEC 61851-23:2023 applies to the EV supply equipment to provide energy transfer between the supply network and electric vehicles (EVs), with a rated maximum voltage at side A of up to 1 000 V AC or up to 1 500 V DC and a rated maximum voltage at side B up to 1 500 V DC. This document specifies the EV supply equipment of system A, system B and system C as defined in Annex AA, Annex BB and Annex…

This document: a) defines metrics as key performance indicators (KPIs) for resilience, dependability, fault tolerance and availability tolerance for data centres; b) covers the data centre infrastructure (DCI) of power distribution and supply, and environmental control; c) can be referred to for covering further infrastructures, e.g. telecommunications cabling; d) defines…
