IEC 60364-5-52:2009+AMD1:2024 CSV deals with the selection and erection of wiring systems. This third edition cancels and replaces the second edition, published in 2001, and constitutes a technical revision. The main changes with respect to the previous edition are as follows:
- Subclause 521.4 introduces minor changes with regard to busbar trunking systems and powertrack systems.
- Subclause…
This document specifies reference wavelengths to be used for the characterization of optical materials, optical systems and instruments, and ophthalmic lenses. It defines the associated principal refractive indices and principal dispersions, as well as the Abbe numbers with regard to these reference wavelengths and principal dispersions.
Optique et photonique — Longueurs d'onde de référence
Le présent document définit des longueurs d'onde de référence à utiliser pour la caractérisation des matériaux optiques, des systèmes et des instruments d'optique et des verres ophtalmiques. Il définit les indices de réfraction principaux et les dispersions principales associées, ainsi que les nombres d'Abbe par rapport à ces longueurs d'onde de référence et aux dispersions…
