19、cal Report is a complementary document to EN 15804 “Sustainability of construction works - Environmental product declarations - Core rules for the product category of construction products”. It is intended to assist the understanding and use of EN 15804 by giving guidance and further explanation. Th

20、is document does not replace any of the standards requirements or introduce any new rules and it is not intended to be used as a stand-alone document. This document provides guidance to CEN Technical Committees for construction products and other bodies such as Environmental Product Declaration prog

21、ramme operators in the construction sector developing Product Category Rules complementary to EN 15804. According to decision BT 3/2013, CEN Technical Committees for construction products are asked to inform CEN/TC 350 at the earliest stage when a complementary PCR document will be developed, allowi

22、ng CEN/TC 350 to arrange a liaison and ensure they can review the document when necessary. PD CEN/TR 16970:2016 CEN/TR 16970:2016 (E) 6 1 Scope This Technical Report provides general guidance to the users of EN 15804 and those preparing complementary Product Category Rules (c-PCRs) by: stating gener

23、al principles for the use of EN 15804 by CEN Technical Committees for construction products (Product TCs) in order to ensure consistency among the complementary PCR produced by Product TCs; addressing the questions raised by Product TCs, manufacturers or their sub-contractors who provide LCA studies

24、 underlying an Environmental Product Declaration (EPD) and by EPD programme operators who include c-PCR of specific subcategories in their PCR registry. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its appl

25、ication. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

28、 which provide additional, compliant and non-contradictory requirements to EN 15804 Note 1 to entry: c-PCR are meant to be used together with EN 15804. 3.2 default values pre-defined results without further calculation 3.3 freshwater water having a low concentration of dissolved solids Note 1 to ent

29、ry: Freshwater typically contains less than 1 000 mg per litre of dissolved solids and is generally accepted as suitable for withdrawal and conventional treatment to produce potable water. Note 2 to entry: The concentration of total dissolved solids can vary considerably over space and/or time. SOUR

31、uding in-stream uses such as fishing, recreation, transportation. Note 2 to entry: The term “water consumption” is often used to describe water removed from, but not returned to, the same drainage basin. Water consumption can be because of evaporation, transpiration, integration into a product, or r

32、elease into a different drainage basin or the sea. Change in evaporation caused by land-use change is considered water consumption (e.g. reservoir). The temporal and geographical coverage of the water footprint assessment are defined in the goal and scope. SOURCE: ISO 14046:2014, 3.2.1, modified 4 A

35、e 5 General aspects 5.1 Objectives 5.1.1 Objectives of core PCR The main objective of EN 15804 is to provide horizontal core PCR for all construction products and services. They are applicable for developing Type III EPD for any construction product or service but can be further detailed in c-PCR. I

36、t is possible to develop and to verify a Type III EPD directly to the EN 15804 standard. If there is no c- PCR available, EPD for construction products are developed only according to EN 15804. The EPD always states according to which standard the EPD was made (EN ISO 14025:2010, 7.2.1, e). PD CEN/T

37、R 16970:2016 CEN/TR 16970:2016 (E) 8 5.1.2 Objectives of the guidance If more detailed specifications and descriptions for a product group are needed it is advisable to develop a c-PCR in compliance with EN 15804. The grouping of products follows the grouping of the Product TCs. Compliance with this

38、 Technical Report is not a requirement for compliance with EN 15804, but product TCs and Program Operators are encouraged to follow this guideline to enhance harmonization The guidance document supports the following principles for developing c-PCR: a) Any c-PCR using EN 15804 as a normative referen

39、ce needs to be compliant with EN 15804. NOTE 1 CEN/TC 350 homepage 1 lists c-PCR documents prepared by Product TCs, that were reviewed to be compliant with EN 15804, or are under review by CEN TC 350/WG 3. b) A common structure of EN 15804 and cPCR provided by Product TCs in order to assist the deve

40、lopment of a consistent set of principles and rules for the construction sector. 1) C-PCR developed by Product TCs use the following common title structure: “title of Product TC - Environmental product declarations Product category rules complementary to EN 15804 product group, depending on name” EX

41、AMPLE Round and sawn timber - Environmental product declarations - Product category rules complementary to EN 15804 for wood and wood-based products for use in construction. 2) The structure of the document maintains the structure of EN 15804. When developing c-PCR Product TCs are recommended to use

42、 a format as described in Table 1. Table 1 Format for the development of complementary PCR in accordance with EN 15804 Clause Text for new c-PCR EN 15804 Comment 5 general aspects, 5.1 Objective of the PCR As in EN 15804, in addition: xxxxxxxx An EPD according to this standard provides quantified en

43、vironmental information for a construction product or service. c) C-PCR provided by Product TCs and considered compliant with EN 15804 by CEN/TC 350 provide a consistent set of principles and rules. In the development of c- PCR the following aspects are considered: 1) Complementary specifications to

44、 the core rules provided by EN 15804, particularly related to: i) the scope of the c-PCR, related to the product group, product type, intended application and use of the product, type of EPD (cradle to gate, cradle to gate with options, cradle to grave); ii) the scope with respect to any required in

45、formation modules A1-C4 and D; iii) specification of the declared or functional unit; iv) allocation rules; PD CEN/TR 16970:2016 CEN/TR 16970:2016 (E) 9 v) system boundary setting; vi) application of the rules for the exclusion of inputs and outputs. 2) Guidance for the life cycle inventory specific

46、ally related to the product group and/or product type for the information modules covered by the type of EPD. 3) Selection of information modules for which more specific requirements and guidance are given. 4) Inclusion of default scenarios related to a specific application of the product including

47、guidance on: i) the specific content of all information modules of the life cycle and information module D, for default scenarios (e.g. use, typical waste processing, for energy recovery, recycling and reuse and disposal); ii) the definition of the end-of-waste status; iii) the technical scenario in

48、formation for all information modules of the product system and information module D; iv) the determination of the RSL and related in-use conditions for a specific application of the product. The following aspects are not part of c-PCR: 5) classes, benchmarks or threshold values for the indicators;

49、6) new indicators as part of the EN 15804 implementation. NOTE 2 New indicators as part of the pre-set basket of indicators are developed in a horizontal standardization process. NOTE 3 Additional LCA based indicators required or permitted by a c-PCR are communicated as additional information. 5.2 Types of EPD with respect to life cycle stages covered 5.2.1 Information Modules In order to structure the sustainability assessment of buildings and to organize the use of data from products for such an assessment, the life cycle of a product and t
