Le présent document spécifie une méthode d'essai générique pour déterminer les caractéristiques d'usure par abrasion des métaux-durs.
L'essai est approprié pour des situations dans lesquelles les laboratoires d'essai ont besoin de simuler des dommages dus à l'abrasion. Le mode opératoire inclut des informations qui permettent d'utiliser cet essai dans des conditions…
This document specifies a generic test method to determine the abrasion wear characteristics of hardmetals.
The test is appropriate for use in situations where test laboratories have a need to simulate abrasive damage. The procedure includes information which enables the test to be used in a variety of different conditions:
a) with counterface wheels of different stiffness (for example steel…
Optical fibres - Part 1-34: Measurement methods and test procedures - Fibre curl
IEC 60793-1-34:2021 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 60793-1-34:2021 establishes uniform requirements for the mechanical characteristic: fibre curl or latent…
Optical fibres - Part 1-34: Measurement methods and test procedures - Fibre curl
IEC 60793-1-34:2021 establishes uniform requirements for the mechanical characteristic: fibre curl or latent curvature in uncoated optical fibres, i.e. a specified length of the fibre has been stripped from coating. Fibre curl has been identified as an important parameter for minimizing the splice loss of optical fibres when using passive alignment fusion splicers or active alignment mass fusion…
Information technology – Fibre channel — Part 147: Physical interfaces - 7 (FC-PI-7)
This standard describes the physical interface portions of high performance optical link variants that support the higher level Fibre Channel protocols including FC-FS-4 (reference [1]) and FC-FS-5 (reference [2]).
FC-PI-7 specifies 64GFC. 32GFC and 128GFC are described in FC-PI-6 (reference [3]) and FC-PI- 6P (reference [4]), respectively.16GFC, 8GFC and 4GFC are described in FC-PI-5 (reference…
Intelligent transport systems — Traffic and travel information messages via traffic message coding —...
This document specifies location referencing rules to address the specific requirements of Traffic Message Channel (TMC) systems, which use abbreviated coding formats to provide traffic and travel information (TTI) messages over mobile bearers (e.g. GMS, DAB) or via exchange protocols like DATEX II. In particular, the rules address the Radio Data System-Traffic Message Channel (RDS-TMC), a means…
Systèmes de transport intelligents — Informations sur le trafic et les déplacements via le codage de...
Le présent document spécifie les règles de référence de localisant pour couvrir les exigences spécifiques des systèmes TMC (Traffic Message Channel - Canal de messages d'informations sur le trafic), qui utilisent des formats de codage abrégés pour fournir des messages d'informations sur le trafic et les déplacements (TTI) en utilisant des supports mobiles (par exemple: GSM, DAB) ou des…

Safety of primary and secondary lithium cells and batteries during transport
IEC 62281:2019+A1:2021 specifies test methods and requirements for primary and secondary (rechargeable) lithium cells and batteries to ensure their safety during transport other than for recycling or disposal. Requirements specified in this document do not apply in those cases where special provisions given in the relevant regulations, listed in 7.3, provide exemptions. NOTE Different standards…
