NOTE For the purpose of determining whether a fabric for use in movable office partitions is able to provide protection against ignition, the fabric is tested in conjunction with a substrate of known flam
13、mability. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of SANS 1423. All standards are subject to revision and, since any reference to a standard is deemed to be a reference to the latest edition of that s
14、tandard, parties to agreements based on this part of SANS 1423 are encouraged to take steps to ensure the use of the most recent editions of the standards indicated below.

17、persistence of flaming of a material, under specified test conditions, after the ignition source has been removed SANS 1423-5:2008 Edition 1.1 4 3.2 afterglow persistence of glowing of a material after cessation of flaming or, if no flaming occurs, after the ignition source has been removed 3.3 flam
18、e-retardant foam, wadding or interliner a foam, wadding or interliner that has been suitably treated or manufactured to render it flame retardant. Flame-retardant foam, wadding or interliner does not ignite within a flame application time of 20 s and the afterflame time does not exceed 5 s NOTE In t
19、erms of ISO 6940, ignition is deemed to have occurred if the material or product ignites within 5 s after removal of the ignition source. 3.4 flaming debris material that separates from a specimen under specified test conditions and that continues to flame as it falls 3.5 flammability the ability, u
20、nder specified test conditions, of a material or product to burn with a flame 3.6 non-flame-retardant foam or wadding foam or wadding that is readily flammable, i.e. foam or wadding that ignites within a flame application time of 20 s 3.7 surface flash rapid spread of flame over the surface of a mat
21、erial, without ignition of the basic structure of the material. 4 Requirements The fabric shall be of one of the flammability performance categories given in 4.1 and 4.2, as required. 4.1 Category 1 When tested in conjunction with a non-flame-retardant foam or wadding (see 6.3), both before and afte
22、r wet treatment (see 6.2), a category 1 fabric shall comply with the requirements given in table 1. 4.2 Category 2 When tested in conjunction with a flame-retardant foam or wadding or in conjunction with a flame-retardant interliner and a non-flame-retardant foam or wadding (see 6.3), both before an
23、d after wet treatment (see 6.2), a category 2 fabric shall comply with the requirements given in table 1. SANS 1423-5:2008 Edition 1.1 5 Table 1 Flammability performance requirements 1 2 3 Property Requirement Test method subclause Surface flash1). No surface flash shall occur 6.5 Separation of flam
24、ing debris . No flaming debris 6.6 Mean afterflame time, s, max. 1 6.6 Mean afterglow time, s, max. 1 6.6 1) Applicable only in the case of raised or pile fabrics. 5 Labelling and marking The flammability performance category shall appear in legible and indelible marking on a label securely attached
25、 to the fabric. 6 Methods of test 6.1 Conditioning Condition the test samples in accordance with SANS 70 before cutting from each test sample the test specimens required for the tests given in 6.5 and 6.6. 6.2 Wet treatment When relevant, wet and dry the specimens in accordance with the procedure gi
26、ven in SANS 1097. NOTE Only the fabric is subjected to a wet treatment. 6.3 Preparation of composite test specimens (simulated partitions) 6.3.1 Materials and dimensions 6.3.1.1 Test frame, as shown in figure 1. SANS 1423-5:2008 Edition 1.1 6 Figure 1 Test frame 6.3.1.2 Foam, wadding or interliner,
27、either non-flame-retardant foam wadding (to be used when category 1 fabrics are being tested) or flame-retardant foam, wadding or interliner (to be used when category 2 fabrics are being tested) of dimensions 120 mm 600 mm and, in the case of foam or wadding, of thickness approximately 6 mm. 6.3.1.3
28、 Fabric under test, of dimensions 120 mm 600 mm. 6.3.2 Make-up of composite specimens In the case of category 1 fabrics, place the non-flame-retardant foam or wadding over the test frame and place the fabric under test over the foam or wadding. In the case of category 2 fabrics, either place the fla
29、me-retardant foam or wadding over the test frame and place the fabric under test over the foam or wadding, or place the non-flame-retardant foam or wadding over the test frame, place the flame-SANS 1423-5:2008 Edition 1.1 7 retardant interliner over the foam or wadding and then place the fabric unde
30、r test over this combination. In all cases, so staple the specimens along the edges that the fabric and foam/wadding/interliner are secure. If the dimensions of the fabric to be tested are insufficient to provide the required size of specimen, staple together shorter pieces of the fabric (without ov
31、erlapping), using not more than four equally spaced metal staples over the full width of the test specimen. In the case of a fabric that is intended to be bonded to a foam or a wadding, the supplier shall provide sufficient samples of the unbonded fabric for testing purposes. 6.4 Sequence of testing
32、 Note 1 A flow chart that illustrates the sequence of testing and the requirements is given in annex D. Note 2 Except for the surface flash test, testing is conducted on composite specimens only. To economize on the quantity of fabric required and on the time and costs involved in testing, perform t
33、he tests in the sequence given in 6.4.1 to 6.4.3. 6.4.1 Stage 1 In the case of a raised or a pile fabric, determine whether surface flash occurs (see 6.5) on test specimens of the fabric only, before the wet treatment (see 6.2). If surface flash does not occur, repeat the test on specimens that have
34、 been subjected to the wet treatment. If surface flash still does not occur, proceed to stage 2. If surface flash occurs on specimens either before or after the wet treatment, no further tests are required. 6.4.2 Stage 2 Test a composite specimen in conjunction with non-flame-retardant foam or waddi
35、ng in accordance with 6.6, before the wet treatment. If the mean afterflame time or the mean afterglow time exceeds 1 s or if there is flaming debris, proceed to stage 3. If the mean afterflame time or the mean afterglow time does not exceed 1 s and there is no flaming debris, retest the fabric afte
36、r the wet treatment. If the mean afterflame time or the mean afterglow time exceeds 1 s or if there is flaming debris, proceed to stage 3. If the mean afterflame time or the mean afterglow time does not exceed 1 s and there is no flaming debris, the fabric complies with the requirements for a catego
37、ry 1 fabric and no further tests are required. 6.4.3 Stage 3 Test a composite specimen in conjunction with either a flame-retardant foam or wadding, or a non-flame-retardant foam or wadding and a flame-retardant interliner, in accordance with 6.6, before the wet treatment. If the mean afterflame tim
38、e or the mean afterglow time exceeds 1 s or if there is flaming debris, then no further tests are required and the fabric fails to comply with the requirements of this part of SANS 1423. If the mean afterflame time or the mean afterglow time does not exceed 1 s and there is no flaming debris, retest
39、 the fabric after the wet treatment. If the mean afterflame time or the mean afterglow time exceeds 1 s or if there is flaming debris, the fabric fails to comply with the requirements of this part of SANS 1423. If the mean afterflame time or the mean afterglow time does not exceed 1 s and there is n
40、o flaming debris, then the fabric complies with the requirements for a category 2 fabric. 6.5 Surface flash Use SANS 6105. SANS 1423-5:2008 Edition 1.1 8 6.6 Afterflame, afterglow and separation of flaming debris Use the method given in ISO 6941, using a flame application time of 20 s, and measure t
41、he mean afterflame time and the mean afterglow time and check for the presence of flaming debris. SANS 1423-5:2008 Edition 1.1 9 Annex A (normative) Notes to purchasers The following requirement shall be specified in tender invitations and in each order or contract: The flammability performance cate
42、gory (see 4.1). Annex B (informative) Quality verification of fabrics of low flammability for use in movable office partitions When a purchaser requires ongoing verification of the quality of fabrics of low flammability for use in movable office partitions, it is suggested that, instead of concentra
43、ting solely on evaluation of the final product, he also direct his attention to the manufacturers quality system. In this connection it should be noted that SANS 9001 covers the provision of an integrated quality system. Amdt 1 Annex C (informative) Guidance for manufacturers Category 2 fabric of lo
