"This European standard provides product category rules (PCR) for Type III environmental product declarations for ""buried plastics piping systems"" intended for buried pressure and non-pressure applications outside building structure. This PCR covers the entire life cycle from cradle to grave. NOTE 1 Examples of standards for which this standard could be applied are listed in Annex C This European Standard specifies the rules for the product category of construction products as defined in and is intended to be used in conjunction with EN 15804. NOTE 2 The assessment of social and economic performances at product level is not covered by this standard. NOTE 3 For the purpose of this standard the word ""building"" is always replaced by ""buried plastics piping systems"" or constructions. NOTE 4 If a comparison is made it has to be based on the same functional unit@ the same layout with same needed minimum flow capacity of the outlets@ the same installation@ same assumptions and the same LCI data sets. The core PCR: (as EN 15804) ?? defines the parameters to be declared and the way in which they are collated and reported; ?? describes which stages of a product's life cycle are considered in the EPD and which processes are to be included in the life cycle stages; ?? defines rules for the development of scenarios; ?? includes the rules for calculating the Life Cycle Inventory and the Life Cycle Impact Assessment underlying the EPD@ including the specification of the data quality to be applied; ?? includes the rules for reporting predetermined@ environmental and health information@ that is not covered by LCA for a product@ construction process and construction service where necessary; ?? defines the conditions under which construction products can be compared based on the information provided by EPD. In addition to the common parts of EN 15804 this European Standard for buried plastics piping systems defines: ?? the Functional Unit; ?? the system boundaries; ?? the elements of installation; ?? the transport scenarios for both the raw material and the complete system; ?? the trench conditions; ?? reference service life (RSL); ?? end of life scenarios; ?? the rules for calculating the Life Cycle Inventory and the Life Cycle Impact Assessment underlying the EPD. This standard is intended to be used for cradle to grave assessment."
