It is the English language version of EN25077:1993 Textiles Determination of dimensional change in washing and drying published by the European Committee for Standardization and is identical with ISO5077:1984. This standard supersedes BS5807
10、:1987 which is withdrawn and which was also identical with ISO5077:1984. As a consequence of implementing the European Standard this British Standard is renumbered as BS EN25077. This edition makes no technical changes to the standard. EN 25077:1993 has been approved by CEN member bodies under the U
11、nique Acceptance Procedure. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pa

22、ard specifies a method for determination of the dimensional change of fabrics, garments or other textile articles when subjected to an appropriate combination of specified washing and drying procedures. In the case of textile articles or deformable materials, it is necessary to exercise all possible
23、 caution in the interpretation of the results. 2 References ISO 139, Textiles Standard atmospheres for conditioning and testing. ISO 3759, Textiles Preparation, marking and measuring of fabric specimens and garments in tests for determination of dimensional change. ISO 6330, Textiles Domestic washin
24、g and drying procedures. 3 Principle The specimen is conditioned in the specified standard atmosphere and measured before subjection to the appropriate washing and drying procedures. After drying, conditioning and remeasuring of the specimen, the changes in dimensions are calculated. 4 Apparatus and
25、 reagents As specified in ISO3759 and in ISO6330. 5 Atmospheric conditions The atmospheric conditions required for pre-conditioning and testing are specified in ISO139. 6 Test specimens 6.1 The selection, dimensions, marking and measuring of test specimens are specified in ISO3759. 6.2 The number of
26、 specimens to be tested is determined by the precision of the results required. In this test method, it is suggested that four specimens of each sample be tested and that these specimens be washed in two separate wash loads with two specimens per wash load (replicates per run). See the Annex. 6.3 In
27、 certain circumstances, it may be desirable not to test four specimens, and fewer specimens may be used. 7 Procedure 7.1 Determine the original length and width dimensions, as appropriate, after the specimens have been pre-conditioned, conditioned and measured according to the procedure specified in
28、 ISO3759. 7.2 Wash and dry the specimens according to one of the procedures specified in ISO6330, as agreed between the interested parties. 7.3 After washing and drying, condition and measure the specimens and calculate the dimensional change of the specimens according to the procedure specified in
29、ISO3759. 8 Expression of results 8.1 Calculate the mean changes in dimensions in both the length and width directions in accordance with the arrangement in ISO3759 as follows: 8.2 Express the average dimensional changes to the nearest 0,5%.
