14、 822:2013 (E) 3 Foreword This document (EN 822:2013) has been prepared by Technical Committee CEN/TC 88 “Thermal insulating materials and products”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical
15、 text or by endorsement, at the latest by September 2013, and conflicting national standards shall be withdrawn at the latest by September 2013. 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
16、responsible for identifying any or all such patent rights. This document supersedes EN 822:1994. The revision of this standard contains no major changes, only minor corrections and clarifications of an editorial nature. This European Standard is one of a series of standards which specify test method
17、s for determining dimensions and properties of thermal insulating materials and products. It supports a series of product standards for thermal insulating materials and products which derive from the Council Directive of 21 December 1988 on the approximation of laws, regulations and administrative p
18、rovisions of the Member States relating to construction products (89/106/EEC) through the consideration of the essential requirements. This European Standard has been drafted for applications in building but it may also be used in other areas where it is relevant. This European test standard is one

It is applicable to thermal insulating products. 2 Normative references This European Standard contains
32、 no normative references. 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 length l longer linear dimension of the major surface of the test specimen 3.2 width b shorter linear dimension of the major surface of the test specimen, measured at r
33、ight angles to the length 4 Principle A test specimen is placed on a flat surface and direct linear measurement is made with a metal rule or a metal tape. 5 Apparatus 5.1 A flat surface. 5.2 Metal rule or metal tape, graduated in millimetres and permitting reading to an accuracy of 0,5 mm. Any test
34、equipment which provides the same result with at least the same accuracy may be used. 6 Test specimens 6.1 Dimensions of test specimens The test specimen shall be the full-size product. 6.2 Number of test specimens The number of test specimens shall be as specified in the relevant product standard.
35、In the absence of a product standard, the number of test specimens may be agreed between parties. 6.3 Conditioning of test specimens The test specimens shall be stored for at least 6 h at (23 5) C. In cases of dispute, they shall be stored at (23 2) C and (50 5) % relative humidity for the time spec
36、ified in the relevant product standard. DIN EN 822:2013-05 EN 822:2013 (E) 6 7 Procedure 7.1 Test conditions The test shall be carried out at (23 5) C. In cases of dispute, it shall be carried out at (23 2) C and (50 5) % relative humidity. 7.2 Test procedure Lay the test specimen carefully on a fla
37、t surface. For test specimens with both dimensions less than or equal to 1,5 m, take one measurement of length, l, and one measurement of width, b, at the positions shown in Figure 1. For test specimens greater than 1,5 m in length, make one additional width measurement for each extra metre of lengt
38、h, up to a maximum of five measurements, with the measurements equally spaced as shown in Figure 2. For test specimens greater than 1,5 m in width, make one additional length measurement for each extra metre of width, with the measurements equally spaced. All lengths and widths shall be read to the
39、nearest millimetre.
