This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by December 2017,

25、 and conflicting national standards shall be withdrawn at the latest by December 2017. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights.

BS EN 16757:2017EN 16757:2017 (E) 5 Introduction The European Standard EN 1580

28、4:2012+A1:2013 provides core rules for all construction products and services. It provides a structure to ensure that all Environmental Product Declarations (EPD) of construction products, construction services and construction processes are derived, verified and presented in a harmonized way. This

29、European Standard provides additional rules for Environmental Product Declarations (EPD) specifically for concrete and concrete elements. It complements the core rules for all construction products and services as established in EN 15804:2012+A1:2013. An EPD communicates verifiable, accurate, non-mi

30、sleading environmental information for products and their applications, thereby supporting scientifically based, fair choices and stimulating the potential for market-driven continuous environmental improvement. The standardization process has taken place in accordance with ISO 14025. All common iss

31、ues are covered horizontally for all product types in order to minimize vertical (branch specific) deviations. All common issues are covered horizontally for all concrete and concrete elements in order to minimize intra-sectorial deviations. EPD information is expressed in information modules as def

32、ined in EN 15804:2012+A1:2013, which allow easy organization and expression of data packages throughout the life cycle of concrete and concrete elements. The approach requires that the underlying data should be consistent, reproducible and comparable. In line with EN 15804:2012+A1:2013 the EPD is ex

33、pressed in a form that allows aggregation (addition) to provide complete information for buildings. This standard does not deal with aggregation at the building level nor does this standard describe the rules for applying EPD in a building assessment. The standard deals with a limited number of quan

34、tifiable parameters as predefined in EN 15804:2012+A1:2013. Future revisions of EN 15804 may lead to the incorporation in this standard of additional predetermined parameters. This European Standard provides the means for developing a Type III environmental declaration of concrete and concrete eleme

35、nts in the context of the suite of standards that are intended to assess the sustainability of construction works. This suite of standards includes: EN 15643-1, Sustainability of construction works Sustainability assessment of buildings Part 1: General framework EN 15643-2, Sustainability of constru

36、ction works Assessment of buildings Part 2: Framework for the assessment of environmental performance EN 15978, Sustainability of construction works Assessment of environmental performance of buildings Calculation methods EN 15804:2012+A1:2013, Sustainability of construction works Environmental prod

39、N 15804:2012+A1:2013 and is intended to be used in conjunction with that standard. This European Standard applies to concrete and concrete elements for building and civil engineering, excluded autoclaved aerated concrete. This document defines the parameters to be reported, what EPD types (and life

40、cycle stages) to be covered, what rules to be followed in order 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+A1:2013, this European Standard for co

41、ncrete and concrete elements: defines the system boundaries; defines the modelling and assessment of material-specific characteristics; defines allocation procedures for multi-output processes along the production chain; defines allocation procedures for reuse and recycling; includes the rules for c

42、alculating the LCI and the LCIA underlying the EPD; provides guidance/specific rules for the determination of the reference service life (RSL); gives guidance on the establishment of default scenarios; gives guidance on default functional units for concrete elements. This document is intended to be

43、used either for cradle to gate, cradle to gate with options or cradle to grave assessment, provided the intentions are properly stated in the system boundary description. Within the construction works context, a cradle to grave declaration delivers a more comprehensive understanding of the environme

44、ntal impact associated with concrete and concrete elements. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
