ASTM D1238-10 Procedure A,B,CStandard Test Method for Melt Flow Rates of Thermoplastics by Extrusion Plastometer
ASTM D1238-10 用挤压塑料计测量热塑性塑料熔体流动速率的试验方法
样品要求：50g～100g粒料或成品
周期： 7~9个工作日
Scope：
This test method covers the determination of the rate of extrusion of molten thermoplastic resins using an extrusion plastometer. After a specified preheating time, resin is extruded through a die with a specified length and orifice diameter under prescribed conditions of temperature, load, and piston position in the barrel.
范围：
这种测试方法包括挤出的熔融的热塑性树脂，采用挤压搪率测定。指定的预热时间后, 树脂是通过用指定的长度和节流孔直径在订明的在机筒的温度、 负荷和活塞位置条件下模具挤压。
