BS EN 50693:2019 pdf free.Product category rules for life cycle assessments of electronic and electrical products and systems.
To quantify the potential environmental impacts caused by EEPS, LCA compliant with EN ISO 14040 and EN ISO 14044 shall be performed. And results can then be used to identify improvement potentials in terms of e.g. environmental conscious product design. In addition, the requirements of this PCR and applicable PSR shall be applied in case the LCA results are further intended to be used in external communication. This is valid when the form of an environmental product declaration (EPD), as laid out in the EN ISO 14021/14025 standards, is used.The product category rules (PCR) provide a uniform approach to perform the LCA, serving three purposes: to ensure a consistent quality of the LCA results, to enable data aggregation in larger systems, e.g. buildings or industrial production machinery, to serve as basis for environmental declarations using quantitative environmental impacts. The PCR should be complemented with corresponding, product specific rules (PSR) to further specify assumptions and methodology to be used for specific product families. Product PSR shall be developed in the respective product technical committees according to the requirements set out in this standard. If there are no PSR available yet but there’s the need for quantitative environmental information based on LCA for a certain product group, the LCA practitioner shall complete the missing specifications according to the requirements of EN ISO 14044 and shall disclose his specifications along with the evaluated data. NOTE For the completion of the missing information various sources might be available, like for instance environmental declaration programs or PSR in standards by other product groups.The FU is used as a reference unit to allow comparison between different alternatives (e.g. products, systems or technical solutions) intended to provide the main functions with the required level of performance. NOTE 1 Some products or systems may have complex FU descriptions, for example multifunctional products such as smartphones. In PSR development it shall be taken into account that the definition of the RSL could lead to distortions for product groups with a considerable range of product life span, where for some products the environmental impacts would be underestimated, while for others it would be overestimated. Hence this should be reflected in the FU and RSL, as well as the EPD, e.g. by providing annualised data.BS EN 50693 pdf download.
