　　高溫流淌性測定儀根據12953-2003，GB/18173-2000GB/T328-2007之規范設計制作。用于防水卷材的高溫流淌性的檢測。

　　First,the product introduction:

　　The high temperature flow tester is designed and manufactured according to the specifications of 12953-2003,GB/18173-2000GB/T328-2007.It is used for the detection of high temperature flowability of waterproof coiled materials.

　　二，20×20×4高溫流淌性測定儀試驗方法：

　　將三個20mm×20mm×4mm的試樣分別置于75°傾角的帶凹槽木架上，使試樣厚度的2mm在槽內，2mm在槽外；一并放入（80±2）℃的干燥箱內，5h后取出，觀察試樣有無明顯流淌，以不超過凹槽邊線1,mm為無流淌。

　　Second,the test method:

　　Place three 20mm×20mm×4mm specimens on a grooved wooden frame with an inclination of 75°,so that the thickness of the sample is 2mm in the groove and 2mm outside the groove;put together(80±2)°C In the dry box,take it out after 5 hours,ａnd observe whether the sample has obvious flow,so as not to exceed the groove edge line 1,mm is no runny.
