标准范围

ISO 12492:2012规定了使用库仑卡尔费休滴定法测定生橡胶和复合橡胶含水量的试验方法。它适用于含水量在0.01%和1%之间的范围。由于这是一种非常敏感的方法，因此必须尽可能避免样品与任何水分接触，甚至与周围环境接触。

ISO 12492:2012 specifies a test method for the determination of water content of raw rubber and compounded rubber using a coulometric Karl Fischer titration method. It applies to the range for the water content between 0,01 % and 1 %. As this is a very sensitive method, contact of sample with any moisture, even from the surrounding environment, must be eliminated as much as possible.
