Road traffic noise reducing devices - Sustainability of construction works - Environmental product declarations - Product Category Rules for road traffic noise reducing devices

This document complements the core rules for the product category of construction products as defined in EN 15804:2012+A2:2019 and is intended to be used as a c-PCR in conjunction with that standard. This document applies for RTNRDs in the context of a civil engineering works. It defines the parameters to be reported, what EPD types (and life cycle stages) to be covered, what rules to be followed to generate Life Cycle Inventories (LCI) and conduct Life Cycle Impact Assessment (LCIA) and the data quality to be used in the development of EPDs. In addition to the common parts of EN 15804:2012+A2:2019, this document for RTNRD - gives guidance on declared units; - defines the system boundaries; - provides guidance/specific rules for the determination of the reference service life; - gives guidance on the establishment of default scenarios.
