11、on of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee
12、. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance w
13、ith the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires appr
14、oval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 21930 was prepared by Technical Commit
15、tee ISO/TC 59, Building construction, Subcommittee SC 17, Sustainability in building construction. ISO 21930:2007(E) ISO 2007 All rights reserved vIntroduction Designers of buildings, manufacturers of building products, users of buildings, owners of buildings and others active in the building and co
16、nstruction sector are increasingly demanding information that enables them to make decisions to address environmental impacts of buildings and other construction works. These demands are currently being addressed only through various national initiatives applying a variety of approaches. It is essen
17、tial that there be uniformity in the means of expressing environmental product declarations. This includes having a consistent way of arriving at the declaration that is based on basic life-cycle inventory data and additional information not based on life-cycle assessment (LCA). The user expects non
18、-biased information, which is expected be consistent with the best current practice and understanding over the lifetime of the standard. According to the set of four International Standards dealing with environmental labelling, (ISO 14020, ISO 14021, ISO 14024 and ISO 14025), environmental labels an
19、d declarations are divided into three principal types: General principles: ISO 14020; Self-declared environmental claims, type II environmental labelling (ISO 14021); Principles and procedures of environmental labels and declarations, types I and III environmental labelling (ISO 14024 and ISO 14025)
20、. This International Standard is one in a suite of International Standards dealing with sustainability in building construction that includes the following: a) ISO 15392 Sustainability in building construction General principles; b) ISO 21932 Buildings and constructed assets Sustainability in buildi
21、ng construction Terminology; c) ISO/TS 21929-1 Sustainability in building construction Sustainability indicators Part 1: Framework for development of indicators for buildings; d) ISO 21930 Sustainability in building construction Environmental declaration of building products; e) ISO/TS 21931-1 Susta
22、inability in building construction Framework for methods of assessment for environmental performance of construction works Part 1: Buildings. Unlike the International Standards listed in a), b), c) and e), ISO 21930 (this International Standard) deals only with environmental impacts and aspects and
23、excludes consideration of the social and economic aspects of sustainability. The relationship among the International Standards is elaborated in Figure 1. ISO 21930:2007(E) vi ISO 2007 All rights reservedFigure 1 Suite of related International Standards for sustainability in building construction an
24、d construction works The purpose of this International Standard is to describe the principles and framework for environmental declaration of building products, including consideration of the reference service life of the building products, seen over a buildings life cycle. This International Standar
25、d is expected to form the basis for type III environmental declaration programmes leading to type III environmental declarations of building products as described in ISO 14025.

26、l declaration of building products 1 Scope This International Standard provides the principles and requirements for type III environmental declarations (EPD) of building products. This International Standard contains specifications and requirements for the EPD of building products. Where this Intern
27、ational Standard contains more specific requirements, it complements ISO 14025 for the EPD of building products. This International Standard provides a framework for and the basic requirements for product category rules (PCR) as defined in ISO 14025 for type III environmental declarations of buildin
28、g products. Type III environmental declarations for building products, as described in this International Standard, are primarily intended for use in business-to-business communication, but their use in business-to-consumer communication under certain conditions is not precluded. This International
29、Standard does not define requirements for developing type III environmental declaration programmes. Requirements for type III environmental declaration programmes are found in ISO 14025. The working environment is not included in this International Standard because it is normally a subject for natio
30、nal legislation. NOTE In this International Standard, EPD is an abbreviation used to represent both the single and plural full form designation of “environmental product declaration”, which is intended to be synonymous with the designation “type III environmental declaration”. In the practice of dev
31、eloping EPD, programmes or their declarations are referred to by various names such as eco-leaf, eco-profile, environmental declaration of product, environmental product declaration (EPD), and environmental profile. 2 Normative references The following referenced documents are indispensable for the

NOTE The terms and definitions in ISO 21932, under preparation at
37、 the publication date of this International Standard, will apply when the document is available. 3.1 ancillary product complementary product building product (3.2) that enables another building product to fulfil its purpose in the intended application EXAMPLE Fasteners used to attached structural pa
38、nels to framing members. 3.2 building product goods or services used during the life cycle of a building or other construction works Adapted from ISO 6707-1 and ISO 14021 NOTE 1 In this International Standard, the term “product” used alone relates not only to goods or product systems but can also in
39、clude service systems. In either case, the declaration is presented in a manner that clearly indicates whether the declaration applies to goods, or to only a part of the goods or packaging, or to an element of service. This is discussed in ISO 14025:2006, 7.2.2. NOTE 2 The manufacturing or processin
40、g of goods used as building products can take place at the factory or on the construction site. NOTE 3 The use of services can occur at any stage of the life cycle of the building or other construction works. NOTE 4 It is possible to have an EPD (3.16) for a material, a building product, a component
41、, an assembly and/or a building element. The EPD of a component, assembly or building element can incorporate the results of the EPD of all the assembled materials and building products. This is described in ISO 14025:2006, 5.4. 3.3 characterization factor factor derived from a characterization mode
