17、reword This document (EN 572-8:2012+A1:2016) has been prepared by Technical Committee CEN/TC 129 “Glass in building”, the secretariat of which is held by NBN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the
18、 latest by August 2016, and conflicting national standards shall be withdrawn at the latest by August 2016. 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 al
19、l such patent rights. This document includes Amendment 1 approved by CEN on 22 November 2015. This document supersedes !EN 572-8:2012“. The start and finish of text introduced or altered by amendment is indicated in the text by tags !“. This document has been prepared under a mandate given to CEN by
20、 the European Commission and the European Free Trade Association. !EN 572-8:2012 was“ a revision of EN 572-8:2004. The main changes in this edition !were“: a) a new method of determination of squareness; b) a new method of measurement for spot fault (including halo) and an adaptation of the related
21、requirements. The European Standard EN 572:2012 “Glass in building Basic soda-lime silicate glass products” consists of the following parts: Part 1: Definitions and general physical and mechanical properties; Part 2: Float glass; Part 3: Polished wired glass; Part 4: Drawn sheet glass; Part 5: Patte

BS EN 572-8:2012+A1:2016EN 572-8:2012+A1:2016 (E) 5 1 Scope This European Standard specifies dimensional and minimum quality requirements (in respect of opt
25、ical and visual faults) for basic soda-lime silicate glass products, as defined in EN 572-1:2012, for use in building. It applies to supplied sizes or cut sizes for final end use. This European Standard does not apply to final cut sizes having a dimension less than 100 mm or a surface area less than
26、 0,05 m. This European Standard does not apply to float glass supplied as jumbo, split sizes or oversize plates nor to polished wired glass, drawn sheet glass, patterned glass, patterned wired glass supplied as stock sizes. For specifications regarding these types of glass, see EN 572-2:2012, EN 572
27、-3:2012, EN 572-4:2012, EN 572-5:2012 and EN 572-6:2012 respectively. This European Standard does not apply to final cut sizes of wired or unwired channel shaped glass For specifications on this type of glass, see EN 572-7:2012. 2 Normative references The following documents, in whole or in part, ar
