标准摘要
[中文适用范围]： 本文件规定了测定线性热膨胀系数的设备和程序。 它适用于-196℃至850℃温度范围内的绝热产品，但受测试样品可能的温度限制。 它不适用于在试验过程中由于失去水合水而发生尺寸变化或发生其他相变的产品。 [外文原描述]： This document specifies the equipment and procedures for determining the coefficient of linear thermal expansion. It is applicable to thermal insulating products within the temperature range −196 °C to 850 °C, subject to the possible temperature limitation of the test specimens. It is not applicable to products which experience dimensional changes during the test due to the loss of hydration water or which undergo other phase changes.
