Paints and varnishes. Determination of scratch resistance - Constant-loading method1 Scope This document specifies a test method for determining under defined conditions the resistance of a single coating or a multi coat system of paint, varnish or related product to penetration by scratching with a scratch stylus loaded with a specified load. Penetration of the stylus is to the substrate, except in the case of a multi coat system, in which case the stylus can penetrate either to the substrate or to an intermediate coat. The method

BS EN IEC 61347‑2‑14 specifies particular safety requirements for electronic controlgear for use on AC supplies up to 1 000 V at 50 Hz or 60 Hz and/or DC supplies with operating frequencies deviating from the supply frequency

Respecting the utilization of digital electronic equipment in I&C systems instead of relay-based devices requires that more detailed consideration shall be given to resistance against electromagnetic disturbances
