IEC 61754-13:2024 defines the standard interface dimensions for the type FC-PC family of connectors. This third edition cancels and replaces the second edition published in 2006. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) revising normative reference reflecting the latest documents;
b…
Earth-moving machinery — Hydraulic excavator and backhoe loader lowering control device — Requiremen...
This document establishes uniform requirements and test procedures for lowering control devices fitted on the boom, intermediate boom and arm cylinders of hydraulic excavators and backhoe loaders to control the rate of drop in the case of a hydraulic line failure or rupture.
It is applicable to the lowering control devices of hydraulic excavators and the backhoe equipment of backhoe loaders used…

Le présent document établit des exigences uniformes et des modes opératoires d'essai pour les dispositifs de contrôle d’abaissement montés sur vérin de flèche ou de bras des pelles hydrauliques ou chargeuses pelleteuses pour contrôler le taux de chute en cas de défaillance ou de rupture du circuit hydraulique.
Il s'applique aux dispositifs de contrôle d’abaissement des pelles…
Identification link - Part 2: Types/models, lots/batches, items and characteristics
IEC 61406-2:2024 complements IEC 61406-1 by providing additional requirements for those cases where data elements are encoded within the Structured Identification Link string with standardized syntax and semantics.
In addition, this document covers cases where the uniqueness relates to product types/models or lots/batches. The default assumption is that the Identification Link identifies unique…
Dimensions, marking and testing of carbon brushes and dimensions of brush-holders for electrical mac...
IEC 60136:2024 applies primarily to brushes and brush-holders for cylindrical commutators and slip rings for electrical rotating machines. Some clauses of this document may cover other configurations, such as flat commutators or plain disks. It defines the dimensions of brushes and their components, together with their tolerances:
- dimensions of brush block (t, a, r),
- angles α and β,
-…
Explosive atmospheres — Part 49: Flame arresters — Performance requirements, test methods and limits...
This document specifies the requirements for flame arresters that prevent flame transmission when explosive gas-air or vapour-air mixtures are present. It establishes uniform principles for the classification, basic construction and information for use, including the marking of flame arresters, and specifies test methods to verify the safety requirements and determine safe limits of use. This…
Fibre-optic communication subsystem test procedures - Part 4-2: Installed cabling plant - Single-mod...
IEC 61280-4-2:2024 RLV contains both the official IEC International Standard and its Redline version. 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 62180-4-2:2024 is applicable to the measurements of attenuation and optical return loss of an installed optical…
Explosive atmospheres - Part 49: Flame arresters - Performance requirements, test methods and limits...
ISO/IEC 80079-49:2024 specifies the requirements for flame arresters that prevent flame transmission when explosive gas-air or vapour-air mixtures are present. It establishes uniform principles for the classification, basic construction and information for use, including the marking of flame arresters, and specifies test methods to verify the safety requirements and determine safe limits of use…
Tissue paper and tissue products — Part 16: Determination of optical properties — Diffuse reflectanc...
This document specifies the testing procedures for the instrumental determination of the opacity of tissue paper or tissue products by diffuse reflectance using a paper backing.
This document contains specific instructions for the preparation of test pieces of single-ply and multi-ply products, where special preparation/procedures might be necessary.
It can be used to determine the opacity of…
Non-destructive testing — Characteristics of focal spots in industrial X-ray systems — Part 1: Pinho...
This document specifies a method for the measurement of effective focal spot dimensions above 0,1 mm of X-ray systems up to and including 1 000 kV X-ray voltage by means of the pinhole camera method with digital evaluation. The tube voltage applied for this measurement is restricted to 200 kV for visual film evaluation and can be selected higher than 200 kV if digital detectors are used.
The…
