Amdt 2 1992 Amended to include an additional two classes of curtain and drape fabrics and to change the requirement for ignition time
6、. Amdt 3 2009 Amended to change the designation of SABS standards to SANS standards, to move reference to legislation to the foreword, to add a definition for “acceptable“, to modify the requirements for cleaning treatment, and to update referenced standards. Foreword This South African standard was
7、 approved by National Committee SABS SC 1084D, Textile products Low flammable textile products, in accordance with procedures of the SABS Standards Division, in compliance with annex 3 of the WTO/TBT agreement. This document was published in August 2009. This document supersedes SABS 1423-2:1992 (ed
8、ition 1.2). A vertical line in the margin shows where the text has been technically modified by amendment No. 3. Reference is made in 1.2 to the “relevant national legislation”. In South Africa this means the National Building Regulations and Building Standards Act, 1977 (Act No. 103 of 1977). Amdt

If the dimensions of an article are insufficient to provide the required size of specimen, staple together shorter pieces of the fabric (without overlapping), using not more than four equally sp
25、aced metal staples over the full width of the test specimen. Amdt 2 b) For vertical blind fabrics (class C or class D, see 3.1), the tests are done in the length direction only. Amdt 2 5.1 Conditioning Condition the test samples in accordance with SANS 70 before cutting from each test sample the tes

28、 cycle in accordance with SANS 960: Procedure C but, in place of the wetting agent, using an acceptable detergent (without perborate) and in the same quantity as for class A.

29、SANS 1423-2:2009 Edition 1.3 6 5.3 Sequence of testing NOTE A flow chart illustrating the sequence of testing and the requirements to be determined is given in appendix B. Amdt 1 To economize on the quantity of fabric required and the time and costs involved in testing, tests shall be performed in t
30、he following sequence: a) Stage 1: In the case of a raised or a pile fabric, determine whether surface flash occurs (see 5.4) on test specimens before cleaning. If surface flash does not occur, repeat the test on specimens cleaned in accordance with the treatment appropriate to the fabric class. If
31、flash still does not occur, proceed to stage 2. If surface flash occurs on specimens either before or after cleaning, no further tests are required. b) Stage 2: Determine the ignition time (see 5.5) on test specimens before cleaning. If the ignition time exceeds 20 s, repeat the test on specimens cl
32、eaned in accordance with the treatment appropriate to the fabric class. If the ignition time still exceeds 20 s, proceed to stage 3. If the ignition time on specimens either before or after cleaning is equal to or less than 20 s, no further tests are required. Amdt 1; amdt 2 c) Stage 3: Perform the
33、test for separation of flaming debris and duration of afterflame and afterglow (see 5.6) on test specimens both before and after cleaning in accordance with the treatment appropriate to the fabric class. Amdt 1 5.4 Surface flash Use SANS 6105. Amdt 1 5.5 Ignition time Use the method given in SANS 69
34、40 for surface ignition. Amdt 1; amdt 2; amdt 3 5.6 Separation of flaming debris and duration of afterflame and afterglow Use the method given in SANS 6941 for surface ignition, but at a flame application time of 20 s. Record any separation of flaming debris and measure the duration of afterflame an
35、d afterglow.

39、s laid down in this part of SANS 1423 When a purchaser requires verification on an ongoing basis of the uniformity of the burning behaviour of low-flammable curtain and drape fabrics produced to this part of SANS 1423, it is suggested that, rather than evaluation of the final product only, he also d
40、irect his attention to the quality management system applied by the manufacturer. In this connection it should be note that SANS 9001 covers the provision of an integrated quality management system. Amdt 3 Appendix D Test and evaluation flow chart The following flow chart illustrates the sequence in
