Release time: October 23, 2016 popularity: three hundred and twenty-five

The suspension device for heat resistance of waterproof coiled materials shall comply with the provisions of GB / T 328 for the determination of anti fluidity of waterproof coiled materials when the temperature rises, and the heat resistance limits of the upper and lower surfaces of the test coiled materials measured at the specified temperature or continuously at different humidity.

The suspension device for heat resistance of waterproof coiled materials is used to test the heat resistance requirements of products, or to specify the heat resistance limit of products, such as the change results of performance after aging. This instrument should be used with oven. The instrument meets the requirements of GB / T 328.11.

The heat-resistant suspension device of waterproof coiled material is composed of clamp, scriber, bolt, etc. First, cut the sample according to the specified size, and then mark out the part of the sample to be scraped out in advance. Put the scraper on the electric furnace (to be prepared by oneself) for heating.
