1 Scope
1.1 The requirements of this standard apply to off-board unidirectional and bidirectional equipment rated
1000 Vac and 1500 Vdc or less, that transfers electrical energy between an electric vehicle and off board
loads as well as operating in parallel with an electric power system, such as the electric utility grid, using a
permanently attached vehicle connector. Equipment that has…
Power installations exceeding 1 kV AC and 1,5 kV DC - Part 2: DC
IEC 61936-2:2023 provides, in a convenient form, requirements for the design and the erection of DC installations in systems with nominal voltages above 1,5 kV DC, so as to provide safety and proper functioning for the use intended.
For the purpose of interpreting this document, a DC installation is considered to be one of the following:
a) A converter station or DC switching station;
b) one (…
Electronic displays - Part 3-5: Evaluation of optical performance - Colour capabilities
IEC 62977-3-5:2023 specifies standard evaluation methods for determining the colour capabilities of electronic display modules and systems with respect to colour accuracy, colour gamut volume, and their intersection with a reference colour space. Also included is evaluation with respect to the chromaticity gamut area. These methods apply to emissive and transmissive direct view displays that…
Sintered metal materials, excluding hardmetals — Unnotched impact test piece
This document specifies the dimensions of an unnotched impact test piece of sintered metal materials. The test piece may be obtained directly by pressing and sintering or by machining a sintered part.
This document applies to all sintered metals and alloys, with the exception of hardmetals. However, for certain materials (for example, materials with low porosity or materials with high ductility…
Effect of conductivity on multipass testing as per ISO 4548-12:2017
This document outlines the importance of conductivity in multi-pass filter testing per ISO 4548-12. This information also applies to filters tested per other multi-pass filter test standards, such as ISO 16889 and ISO 19438. Filters tested according to each method can experience similar changes in performance during the fluid conductivity changes outlined within this document.
The objectives of…
Washing machines for household use - Method for measuring the microbiological performance
IEC TS 63429:2023 provides a test method for measuring the microbial contamination reduction performance of household washing machines with textile pieces contaminated with test microorganisms under standardized conditions. The microbial numbers on the contaminated textile pieces are measured before and after the washing programme and the reduction is calculated. Furthermore, a potential cross…
Optical fibre cables - Part 1-306: Generic specification - Basic optical cable test procedures - Cab...
IEC 60794-1-306: 2023 describes test procedures to verify the mechanical and functional integrity of the fibre ribbon structure. The test determines the capability of the ribbon to withstand torsion without delamination between optical fibre and ribbon bonding agent. This document applies to optical fibre ribbons in optical cables for use with telecommunication equipment and devices employing…
Representation of communication in power utility automation
IEC TS 63266:2023 specifies a structure for representation of exchanged information that is essential for testing and maintenance of the devices in power utility automation systems. It is mainly intended to be applied to communication equipment that communicate information in accordance with IEC 61850 (all parts) in at least one part of their communication flow.
The following communication…
This document establishes protocols for testing of 3-D surface-scanning systems in the acquisition of human body shape data and measurements. It does not apply to instruments that measure the motion of individual landmarks.
While mainly concerned with whole-body scanners, this document is also applicable to body-segment scanners (head scanners, hand scanners, foot scanners). It applies to body…
