　　高温流淌性测定仪根据12953-2003，GB/18173-2000GB/T328-2007之规范设计制作。用于防水卷材的高温流淌性的检测。

　　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高温流淌性测定仪试验方法：

　　将三个20mm×20mm×4mm的试样分别置于75°倾角的带凹槽木架上，使试样厚度的2mm在槽内，2mm在槽外；一并放入（80±2）℃的干燥箱内，5h后取出，观察试样有无明显流淌，以不超过凹槽边线1,mm为无流淌。

　　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.
