Consequently, JIS L 4406: 1995 was revised and has been replaced with
4、this Standard. In this revision, the following revised points have been carried out; in order to change JI$ mark in this Standard into the specified mark based on the Fire Service Law, “classification by flame resistance” (#!k j the provisions, needed when the manufacturing facilities authorized by

9、PANESE INDUSTRIAL STANDARD (E3 JIS L 4405 : 1997 Tufted carpets 1 Scope This Japanese Industrial Standard specifies tufted carpets (l) to be used for floor covering (hereafter referred to as “tufted carpets”). However, tile carpets are excluded. Note (I) The tufted carpet herein stated is defined as
10、 the floor covering in which pile is formed by putting pile yarn into ground fabric by tufting machine and the pile has been fixed to its back with adhesives. 2 Normative reference The following standards contain provisions which, through reference in this Standard, constitute provisions of this Sta

Allow the test specimens to stand in the thermostatic d
45、ryer at (50 f 2) O C for 24 hours. When handling the test specimen (6) with no apprehension to be affected by heat, instead of the preparation above, standing them in a thermostatic dryer at (105 f 2) O C for one hour may be effective. Then, allow them to stand in a desiccator with a silica gel for
46、at least 2 hours. Notes (4) If necessary, brush them to raise pile on the surface. (5) When test specimen with specified size cannot be picked up, use the sample as it is an original size. (9 Among the specimens whose pile is made 100 % wool fiber, this is the specimen which has no apprehension to b
47、e affected by heat. 8 . 6 . 3 Procedures Procedures shall be carried out as follows. Take out one by one test specimen from a desiccator, put it promptly on the perlite board which has been at the same temperature as that in laboratory, and hold its periphery with a holder frame to fix in a combusti
48、on test box. Set the burner horizontally, heat it for 30 seconds with keeping its top apart 1 mm from the surface of the specimen, and measure afterflame time. Detach the specimen from the holder frame, and measure the distance of carbonization with a scale. Make judgement on 3 test specimens which were respectively prepared longitu- dinally and transversely. 8.7 Oily content and the extract by solvent in pile yarn To test oily con- tent, follow 7 . 2 8 . 2 of JIS L 1096.
