Nanomanufacturing – Product specification – Part 5-3: Nanoenabled energy storage – Blank detail spec...
IEC TS 62565-5-3:2025 which is a Technical Specification, establishes a standardized method to determine a blank detail specification (BDS) for
• silicon nanosized materials
used for
• negative electrode of lithium-ion batteries.
This document is intended to be used for silicon nanosized materials for the negative electrode of lithium-ion batteries which have been widely employed in the…
IEC TS 62565-4-4:2025 which is a Technical Specification, establishes a standardized method to determine a blank detail specification (BDS) for
- quantum dot enabled light conversion film (Q-LCF).
This document is intended to be used for nano-enabled photoelectric display, based on liquid crystal display (LCD).
The relevant key control characteristics (KCC) of Q-LCF are listed, including…
Information technology - Biometric sample quality - Part 5: Face image data
This document establishes requirements on implementations that quantify how a face image’s properties conform with those of canonical face images, for example those specified in ISO/IEC 39794-5:2019, Clause D.1, for three use-cases:
1) collection of reference samples for ID documents;
2) sample system enrolment; and
3) probes for instantaneous response.
This document also…
Information technology - Coding of audio-visual objects - Part 32: File format reference software an...
This document describes the reference software and conformance suite for the file format documents in multiple standards. Since these standards share a lot of technology, their reference software and conformance program are being handled together. These standards are: ISO/IEC 14496-12, ISO/IEC 14496-14, ISO/IEC 14496-15, ISO/IEC 14496-30 and ISO/IEC 23008-12.
The purpose of the conformance suite…
Railway infrastructure — Rail fastening systems — Two directional test method for resistance to repe...
This document describes a test procedure for the determination of resistance to repeated loading by – amongst others – applying out-of-phase load cycles which generate forces in two directions, representative of those caused by traffic on railway track, taking into account the effect of two consecutive axles of passing railway vehicles.
Nontissés — Méthodes d’essai — Partie 5: Détermination de la résistance à la pénétration mécanique (...
Le présent document spécifie une méthode de détermination de la résistance à la pénétration mécanique des étoffes non tissées par une bille d’un diamètre donné.
Cette méthode est essentiellement destinée à être utilisée sur des nontissés ayant un certain degré d’élasticité, pour lesquels un essai d’éclatement normal ne s’applique pas.
Nonwovens — Test methods — Part 5: Determination of resistance to mechanical penetration (ball burst...
This document specifies a method for determining the resistance to mechanical penetration of nonwoven fabrics by a ball of a given diameter.
The method is primarily designed to be used on nonwovens with some degree of elasticity, for which a regular burst test does not apply.
