【Product knowledge】： | Scope: textiles for home decoration, mattresses, etc. (1) Poroelastic material requirements:
① After all samples are burned, the average carbon length shall not exceed 15. 24 cm;
②After burning any sample, the maximum carbon length shall not exceed 20. 32 cm;
③The average afterburn time of all samples, including the melted part and the fragments falling from the sample, shall not exceed 5 s;
④The average afterburning time of any sample (including the melted part and the fragments falling from the sample) shall not exceed 10 s;
⑤The average smoldering time of all samples (including the melted part and the fragments falling from the sample) shall not exceed 15 s. Try to collect at least 2 sets of samples, each with at least 10 samples, the size is 30. 48 cm × 7. 62 cm × 1. 27 cm, 5 samples are tested before aging, and 5 samples are tested after aging. (2) The requirements for porous elastic fragment materials (such as polyurethane foam fragments) are the same as those in (1) porous elastic materials in this section. There are 20 test samples, which are tested according to the method in Table 1. To
Table 1 Test method for combustibility of porous elastic fragment materials
Flame burning time/s Longitude and weft direction Samples/pieces 3 Warp direction 5 3 Weft direction 5 12 (3) The requirements for non-man-made fiber filling materials are the same as in this section (1) Porous elastic materials.
(4) The requirements for fluffy materials and down and feather materials are the same as those for (1) porous elastic materials in this section. The number of test samples is 20, and the detection method is the same as that shown in Table 1.
(5) Man-made fiber filling material requirements:
①The average flame spread time of all samples shall not be less than 10 s;
②The minimum flame spreading time of any sample shall not be less than 7 s;
③ Regardless of whether the man-made fiber filler contains any woven or non-woven materials during the test, such as coarse cloth and cheese gauze, these requirements must be met;
④ Whether it is tested from the length or width direction of the fabric, man-made fiber filling materials should meet these requirements.
To
Test
The sample is a cuboid with a surface size of 15. 24 cm × 7. 62 cm. The thickness is determined by the tested filling material. At least five samples are taken for measurement. To
(6) The method of elastic filling material, the cigarette burning method. All elastic filling materials are required (except elastic porous materials,
Such as foam), measured from the burning point of the cigarette to any direction, the maximum carbonization length of all samples shall not exceed 5. 08 cm. The test sample is cuboid with a surface size of at least 30. 48 cm × 30. 48 cm, and the thickness is determined by the tested filling material. (7) Closed smoke detection with elastic porous material method. It is required to calculate the percentage of the total board mass that does not fall off the foam board. When testing the foam, the size of the foam on the vertical board is 18. 42 cm × 20. 32 cm × 5. 08 cm, and the size of the foam on the horizontal board is 20. 32 cm × 10. 16 cm × 5. 08 cm. Each foam board measured must be 3 times. |
