GB/T 3140-2005 in English

《GB/T 3140-2005纤维增强塑料平均比热容试验方法》由TC39（全国纤维增强塑料标准化技术委员会）归口，主管部门为中国建筑材料联合会
本标准规定了用混合法院(采用铜块量热计)测定纤维增强塑料平均比热容的试样、试验原理、仪器设备、试验步骤、结果计算和试验报告。本标准适用于测试平均温度约85℃(150℃～20℃)，即试样被加热到150℃的纤维增强塑料的平均比热容。本标准不适用于在150℃时发软变形的材料。

Scope

This standard specifies the sample, test principle, equipment, test procedure, result calculation and test report for measuring the average specific heat capacity of fiber reinforced plastics by the hybrid method (using copper block calorimeter). This standard is suitable for testing the average specific heat capacity of fiber reinforced plastics with an average temperature of about 85°C (120°C~20°C), that is, the sample is heated to 150°C. This standard does not apply to materials that soften and deform at 150°C.
