19、y 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. This document does not replace
20、 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 programme operators in the const
21、ruction 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, allowing CEN/TC 350 to arrange a l
22、iaison and ensure they can review the document when necessary. PD CEN/TR 16970:2016CEN/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 general principles for the use of
23、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 underlying an Environmental
24、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 application. For dated references
25、, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

28、mpliant 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 entry: Freshwater typically cont
29、ains 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. SOURCE: ISO 14046:2014, 3.1.1 PD
30、CEN/TR 16970:2016CEN/TR 16970:2016 (E) 7 3.4 water use use of water by human activity Note 1 to entry: Use includes, but is not limited to, any water withdrawal, water release or other human activities within the drainage basin impacting water flows and/or quality, including in-stream uses such as f
31、ishing, 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 release into a different draina
32、ge 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 Abbreviations ADP Abiotic deple

35、ives 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. It is possible to develop and t
36、o 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/TR 16970:2016CEN/TR 16970:2016 (
37、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 Technical Report is not a requi
38、rement 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 reference needs to be compliant with EN
39、 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 development of a consistent set of p
40、rinciples 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” EXAMPLE Round and sawn timber - En
41、vironmental 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 a format as described in Table
42、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 environmental information for a co
43、nstruction 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 the core rules provided by EN 1
44、5804, 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 information modules A1-C4 and D; i
45、ii) specification of the declared or functional unit; iv) allocation rules; PD CEN/TR 16970:2016CEN/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 specifically related to the product group
46、 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 guidance on: i) the specific cont
47、ent 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 information for all information mod
48、ules 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; 6) new indicators as part of the
49、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 the life cycle of a building are
