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. This European test standard is one of the following group of interrelated standards on test methods for determining di

BS EN 822:2013EN 822:2013 (E) 5 1 Scope This European Stan
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

For products 3 m in length or greater, the length value shall be rounded to the nearest 5 mm. 9 Accuracy of measurement NOTE It has not been possible to include a statement of the accuracy of the method in this edition of
39、 the standard, but it is intended to include such a statement when the standard is next revised. 10 Test report The test report shall include the following information: a) reference to this European Standard; b) product identification: 1) product name, factory, manufacturer or supplier; 2) productio

Information about the apparatus and identity of the technician should be available in the laboratory, but it
42、 need not be recorded in the report; d) results: all individual values and the mean value for each dimension.
