14、 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 methods for determining dimensions and properties of thermal insulating materials and pro

15、ducts. 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 provisions of the Member States relating to construction products (89/106/EEC) throu

16、gh 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.

29、dard specifies the equipment and procedures for determining the length and width of full-size products. It is applicable to thermal insulating products. 2 Normative references This European Standard contains no normative references. 3 Terms and definitions For the purposes of this document, the foll

30、owing 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 right angles to the length 4 Principle A test specimen is placed on a flat surface and direct

31、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 equipment which provides the same result with at least the same accuracy may be used. 6 Test

32、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. In the absence of a product standard, the number of test specimens may be agreed between part

33、ies. 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 specified in the relevant product standard. BS EN 822:2013EN 822:2013 (E) 6 7 Procedure 7.1 Test

34、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 flat surface. For test specimens with both dimensions less than or equal to 1,5 m, take one measureme

35、nt 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 length, up to a maximum of five measurements, with the measurements equally spaced as shown in Figure 2

36、. 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 nearest millimetre. Key l length b width Figure 1 Positions for measuring length and width of a te
