This document provides guidance to manufacturers of measuring equipment for electrical and electromagnetic quantities (ME3Q) in evaluating and improving the environmental impact of their products, and in enabling effective communication using common references for environmental information throughout the supply chain. NOTE - ME3Q devices are described in Annex A. This standard covers only the below fixed installed measuring equipment: - IEC 61557-12 (PMD) - IEC 62586-1 (PQI) - IEC 60688 (TRD) - IEC 62974-1 (DDM) This document provides: guidance on the process and general aspects to implement environmentally-conscious product design principles, as given in ISO/IEC 62430; the Product Specific Rules (PSR) for Life Cycle Assessment (LCA); NOTE 1 The general methods and the process to execute the LCA are in accordance with ISO 14040 and ISO 14044 but not addressed in this document. NOTE 2 PSR and LCA can be used for quantitative ECD and also apply for some environmental declarations, for example Type III. standard environmental impact data derived from case studies and a means of using them; NOTE 3 This is to encourage manufacturers to apply more effective quantitative methods in the ECD process to improve the environmental efficiency of their products. common rules for communicating information about the presence of regulated substances and the materials contained in the product; guidance on communicating information about the end-of-life treatment of the product.
