GB/T 1462-2005 in English

《GB/T 1462-2005纤维增强塑料吸水性试验方法》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
本标准规定了纤维增强塑料在规定尺寸、温度和浸水时间下测定吸水量的设备、试样、试验步骤、计算、试验结果和试验报告。本标准适用于测定纤维增强塑料的吸水性，其结果仅作对比之用，而不用于表示可能吸人的最大吸水量。只有尺寸相同、物理状态尽可能相同的试样才能进行吸水性的比较。本标准规定的两种方法的浸水温度分别是23℃和沸水温度。在沸水温度下会发生软化以至失去原来形态的纤维增强塑料，只能在23℃下试验。

This standard specifies the equipment, specimen, test procedures, calculation, test results and test report for determining the water absorption of fiber reinforced plastics under given dimensions, temperature and immersion time.
This standard is applicable to determine the water absorption of fiber reinforced plastics, where the results are only used for comparison rather than indication of the possible maximum water absorption. Only specimens with same dimensions and possibly same physical conditions can be subject to comparison of water absorption.
The immersion temperatures of the two methods specified in this standard are 23℃ and boiling temperature respectively. Fiber reinforced plastics that may be softened under boiling temperature so as to lose the original form can only be tested at 23℃.
Note: during referee test, the boiling temperature is limited to 100℃±2℃.
