IEC 60875-1:2024 applies to non-wavelength-selective fibre optic branching devices, all exhibiting the following features:
- they are passive, in that they contain no optoelectronic or other transducing elements;
- they have three or more ports for either the entry or exit, or both, of optical power, and share optical power among these ports in a predetermined fashion;
- the ports are optical…

Stainless steel bars for the reinforcement of concrete
This document specifies technical requirements for hot rolled stainless steel plain bars and ribbed bars used as reinforcement in concrete.
It is applicable to steel delivered in the form of bars, coils and de-coiled products. It does not apply to ribbed bars produced from finished products
The production process is at the discretion of the manufacturer.
Guideline for the system design of HVDC converter stations with line-commutated converters
IEC TR 63127:2019+AMD1:2024 CSV focuses on the system design of converter stations. It is applicable to point-to-point and back-to-back HVDC systems based on line-commutated converter (LCC) technology. This document provides guidance and supporting information on the procedure for system design and the technical issues involved in the system design of HVDC transmission projects for both…
Leather — Tests for colour fastness — Colour fastness to crocking
This document specifies a method to determine the amount of colour transferred from the surface of coloured leather to other surfaces by rubbing.
Two tests are carried out, one with a dry rubbing cloth and one with a wet rubbing cloth.
The method is applicable to all types of coloured leather. Since after‑treatments of the leather as well as surface finishes can affect the degree of colour…
