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 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…

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…

IEC 61851-24:2023, together with IEC 61851-23, applies to digital communication between a DC EV supply equipment and an electric road vehicle (EV) for control of conductive DC power transfer, with a rated supply voltage up to 1 000 V AC or up to 1 500 V DC and a rated output voltage up to 1 500 V DC. This document also applies to digital communication between the DC EV charging/discharging…

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 62056-6-1:2023 specifies the overall structure of the OBject Identification System (OBIS) and the mapping of…

IEC 60228:2023 CMV contains both the official standard and its commented version. The commented version provides you with a quick and easy way to compare all the changes between IEC 60228:2023 edition 4.0 and the previous IEC 60228:2004 edition 3.0. Furthermore, comments from IEC TC 20 experts are provided to explain the reasons of the most relevant changes, or to clarify any part of the content…

IEC 60228:2023 specifies the nominal cross-sectional areas, in the range 0,5 mm2 to 3 500 mm2, for conductors in electric power cables and cords of a wide range of types. Requirements for numbers and sizes of wires and resistance values are also included. These conductors include solid, stranded and Milliken, copper, aluminium and aluminium alloy conductors in cables for fixed installations and…
