ASTM C165
Standard Test Method for Measuring Compressive Properties of Thermal Insulations
The compressive resistance is determined on either rigid board or blanket insulation. Specimens can be square or circular with a preferred width or diameter of 6". Testing of four specimens per type/brand is recommended by ASTM.
​
ASTM C167
Standard Test Methods for Thickness and Density of Blanket or Batt Thermal Insulations
One representative roll of insulation is required. Density is calculated from weight and dimensional measurements.
​
ASTM C203
Standard Test Methods for Breaking Load and Flexural Properties of Block-Type Thermal Insulation
Flexural strength is determined on 1" x 4" x 12" specimens. Testing of four specimens per type/brand is recommended by ASTM.
​
ASTM C303
Standard Test Method for Dimensions and Density of Preformed Block and Board-Type Thermal Insulation
Minimum specimen size is 4 x 8 in cross-section. Density is calculated from weight and dimensional measurements.
​
ASTM C356
Standard Test Method for Linear Shrinkage of Preformed High-Temperature Thermal Insulation Subjected to Soaking Heat
Standard Test Method for Linear Shrinkage of Preformed High-Temperature Thermal Insulation Subjected to Soaking Heat
​
ASTM C686
Standard Test Method for Parting Strength of Mineral Fiber Batt- and Blanket-Type Insulation
Tensile strength is measured on O-ring specimens. A 5 sq. ft. representative section of insulation should be submitted.
​
ASTM C892
Standard Specification for High-Temperature Fiber Blanket Thermal Insulation
A 10 gm specimen is fired to 2300°F and forced consecutively through No. 30, 50, and 70 screens. Shot content is determined by percent retained on each screen.
​
ASTM C892
Thermal Conductivity of Fibrous Insulating Material
The heat flow through a material is determined with a water-cooled copper calorimeter. The temperature limit must be specified, as well as the hot face or mean test temperatures desired. The maximum hot face temperature for testing is 2700°F. The standard sample of fibrous insulation requires that new material be available to make a 18" x 13.5" x 2" pad. As blankets are available in several thicknesses, it is often necessary to cut several pieces of blanket that can be placed one upon the other to make the 2" thickness.
