Scope
1.1 This test method covers two procedures for determining the compressive resistance of thermal insulations.

1.1.1 Procedure A covers thermal insulations having an approximate straight-line portion of a load-deformation curve, with or without an identifiable yield point as shown in Figs. 1 and 2. Such behavior is typical of most rigid board or block-type insulations.

 Procedure A???Straight Line Portion with DefinitexA;Yield Point
FIG. 1 Procedure A???Straight Line Portion with Definite Yield Point
 Procedure A???Straight Line Portion but no DefinitexA;Yield Point
FIG. 2 Procedure A???Straight Line Portion but no Definite Yield Point

1.1.2 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 compressed previously to at least the same deformation by compression packaging or mechanical softening.

 Procedure B???Increasing Stiffness
FIG. 3 Procedure B???Increasing Stiffness

1.2 It is recognized that the classification of materials under Procedures A and B shall not hold in all cases. For example, some batt or blanket materials that have not been compression packaged will exhibit behavior more typical of Procedure A for their first loadings. Also, some higher density fibrous insulation boards that have been precompressed will exhibit load-deformation curves more typical of Procedure B. There will also be t......
