Scope适用范围 1.1 This test method covers two procedures for deter-mining the compressive resistance of thermal insulations.本试验方法包括两个测量绝热材料抗压强度的程序。 Procedure A covers thermal insulations having an approximate straight-line portion of a load-deformation curve, but that may or may not have an identifiable yield point as shown in Figs. 1 and 2. Such behavior is typical of most rigid board or block-type insulations程序A包含的绝热材料的载荷变形曲线带直线部分，但如图1和2所示也许带或不带容易辨认的屈服点。大部分刚性绝热板或绝热砖具有此种特征。 Procedure B covers thermal insulations that become increasingly more stiff as load is increased, as shown in Fig. 3. Such behavior is typical of fibrous batt and blanket insulations that have been c
