当试样(100 mm x 100 mm x 25 mm)在规定的环境中放置一定时间并进行修复时,线性尺寸变化的测定。该方法建议了一系列温度和湿度条件,从中可以选择一个或多个所需的试验条件。
Determination of the changes of linear dimensions which occur when the test specimens (100 mm x 100 mm x 25 mm) have been subjected to specified environments for a definite period of time and reconditioned. The method suggests a range of conditions of temperature and humidity, from which one or more of the desired test conditions can be selected.
