Abstract
СПОСОБ ОПРЕДЕЛЕНИЯ ПЫПЕПРОНИЦАЕМОСТИ СПЕЦОБУВИ путем динамических испытаний ее в пылевой камере и измерени количества пыли во внутриобувном пространстве, отличающийс тем, что, с целью повышени точности измерений, в качес ве пыли в камере используют флуоресцирующий порошок, во внутриобувное пространство вставл ют носитель, пропитанный клейким фиксирующим пыль составом на основе поливинилового спирта, по окончании испытаний носитель извлекают из обуви, подвергают экстрагированию в воде, возбуждают люминесценцию водного раствора и по интенсив ности ее суд т о пылепроницаемости. (ЛMETHOD FOR DETERMINING SPETSOBUI'S FIRE-PERMEABILITY by dynamically testing it in a dust chamber and measuring the amount of dust in the intra shoe space, characterized in that, in order to improve measurement accuracy, a fluorescent powder is used in the camera dust, dust composition based on polyvinyl alcohol, at the end of the test, the carrier is removed from the shoe, subjected to extraction in water, excites the luminescence of the aqueous solution the thief and the intensity of the it is judged on pylepronitsaemosti.
