24、055:2016 (E) 5 European foreword This document (EN 13055:2016) has been prepared by Technical Committee CEN/TC 154 “Aggregates”, the secretariat of which is held by BSI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsem

25、ent, at the latest by November 2016, and conflicting national standards shall be withdrawn at the latest by February 2018. 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 identi

26、fying any or all such patent rights. This document supersedes EN 13055-1:2002 and EN 13055-2:2004. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports basic work requirements of EU Regulation. For relationship

27、with EU Regulation see informative Annex ZA, which is an integral part of this document. The most significant changes compared to the previous editions include: a) Merging of the former 2 parts and simplifying the title of the standard; b) Amending terminology and Annex ZA to be consistent with the

28、Construction Products Regulation; c) Clarifying the scope of the standard to cover construction products only; d) Adding a new normative Annex A dealing with all source materials considered to be within the scope; e) Referring certain recycled aggregates and MIBA to other aggregate standards (same p

29、roduct family); f) Referring certain LWA for specific applications to other aggregate standards in a new normative Annex B; g) Replacement of 3 former test method annexes with normative references to new, separate EN test method standards; h) Reorganisation and alignment of text in subclauses under

30、Clause 5 Product characteristics; i) Adding a new general clause on dangerous substances; j) Replacement of former clause on Evaluation of Conformity, and the normative text from the former annex on Factory Production Control, with new normative clauses on Assessment and Verification of Constancy of

31、 Performance; k) Adding a new informative Annex D describing a test method for determination of water absorption for fine LWA. BS EN 13055:2016EN 13055:2016 (E) 6 No changes to existing technical classes and/or threshold levels have been made. Characteristics for other aggregates are specified in th

32、e following European Standards: EN 12620, Aggregates for concrete, EN 13043, Aggregates for bituminous mixtures and surface treatments for roads, airfields and other trafficked areas, EN 13139, Aggregates for mortar, EN 13242, Aggregates for unbound and hydraulically bound materials for use in civil

33、 engineering work and road construction, EN 13383-1, Armourstone - Part 1: Specification, EN 13450, Aggregates for railway ballast. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austri

BS EN 13055:2016EN 13055:2016 (E) 7 1 Scope This European Standard specifies the properties of Lightweight Aggregates (LWA) and fillers derived thereof obtained by processing natural or manufactured materials and mixtures of these aggregates for concrete,

36、 mortar and grout, bituminous mixtures and surface treatments and for unbound and hydraulically bound applications in construction works. This European Standard covers LWA of mineral origin having particle densities not exceeding 2000 kg/m3(2,000 Mg/m3) or loose bulk densities not exceeding 1200 kg/

37、m3(1,200 Mg/m3) including: a) natural LWA; b) LWA manufactured from natural materials; c) LWA manufactured from by-products of industrial processes or from recycled source materials; d) LWA as by-products of industrial processes. A list of source materials and specific materials, which are within th

38、e scope of this standard, is given in Annex A (normative). NOTE Recycled aggregates from construction and demolition waste and Municipal Solid Waste Incinerator Bottom Ash (MIBA) are covered by EN 12620, EN 13043, EN 13139 and EN 13242. Some LWA for specific applications are covered in separate Euro

39、pean product Standards (Annex B, normative). The requirements specified in this European Standard may not be equally relevant to all types of LWA. For particular applications, the requirements and tolerances can be adapted for the end use. 2 Normative references The following documents, in whole or
