Veneers — Terms and definitions, determination of physical characteristics and tolerances
This document establishes the standard terms and definitions (including those relative to features and defects), the methods for the determination of physical characteristics and the tolerances for dimensions (length, width, thickness) for wood veneers, including natural, treated and multilaminar veneers, that can be obtained by slicing, rotary cutting or sawing. The specific definitions,…

L'IEC 62485-5:2020 s'applique à l'installation d'une ou de plusieurs batteries d'accumulateurs stationnaires ayant une tension continue cumulée maximale de 1 500 V sur toute partie sous tension continue du réseau d'alimentation, et décrit les principales mesures de protection en fonctionnement normal ou dans des conditions de défaut prévues contre les dangers…
Photovoltaic devices - Part 14: Guidelines for production line measurements of single-junction PV mo...
IEC TR 60904-14:2020 provides guidelines for measurements of the maximum power (Pmax) output of single-junction photovoltaic (PV) modules and for reporting at standard test conditions (STC) in industrial production line settings. As it is desirable to have consistent measurement practices across the industry, this document describes the following features of such measurements:
- Essential…
