General Rules 1.1 Scope This Japanese Industrial Standard specifies the testing
6、 method for incombustibility by the 45“ Meeker burner method on the board, plate, sheet, film, thick cloth and other similar float materials which are less than 5 mm in thick. However, this testing method can not be applied to the effective evaluation of the incombustibility of the thin material hav
7、ing a performance failing to meet the anti-flame Grade 3 as specified in 2.1. 1.2 For the incombustibility test, use the specimen as specified in 3. and carry out the heat test by the method as specified in 5. by the heat- test apparatus as specified in 4. 1.3 Where the properties of the both sides
8、of material are different, carry out the tests on the both sides. 1.4 Where the quality of material is different according to the part of material, carry out the test on each part. 1.5 Where the material has a directional property, carry out the test on each direction. 2. Kind of Incombustibility 2.
9、1 The kind of incombustibility shall be classified as shown in Table 1. Table 1 Note (l) Maximum about one second. 3.

Method A Dry the specimen in the air-dried condition at the tem- perature of 50 + 2C for 48 h and leave it alone in the desiccater filled with the-silica gel for drying for 24 h and then carry out the heat test. Method B water that has a weig
12、ht not more than 20 times the weight of speci- men and the temperature of 50“C, dry it at a temperature of 50 + 2C for 48 h. Next, after leaving it alone in the desiccater filled with the silica gel for drying for 24 h, carry out the heat test. After immersing the specimen for 30 min in the warm 4.
13、Heat-Test Apparatus 4.1 The heat test shall be carried out in the container by using the apparatus as shown in Appended Figure. 4.2 As a burner for the heat test, use the Meeker burner having the heights of 160 mm and the inside diameter of 20 mm, and put only the gas in the burner without mixing th
