Compressive Properties of Thermal Insulations. T9404 |
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. |
| C-167 |
Thickness And Density of Blanket Or Batt Thermal Insulations. T9405 |
One representative roll or bundle of insulation is required. Density is calculated from weight and dimensional measurements. |
| C-303 |
Density of Preformed Block. Type Thermal Insulation. T9406 |
Minimum specimen size is 4" x 8" in cross-section. Density is calculated from weight and dimensional measurements. |
| C-356 |
Linear Shrinkage of Preformed High. Temperature Thermal Insulation Subjected To Soaking Heat. T9505 |
Linear shrinkage is determined after a Thermal insulating material is exposed to soaking heat for 24 hours. Four 6" x 2 1/2" x 1" or 2" specimens are required by ASTM. |
| C-892 |
Unfiberized Shot Content of Inorganic Fibrous Blankets. T9715 |
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. |
| C-892 |
Thermal Conductivity of Fibrous Insulating Material. T9716 |
The heat flow through a refractory is determined with a water-cooled copper calorimeter. the temperature limit of refractory 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 specimens required are six 9" bricks or an 18" x 13.5" x 2.5" slab. |
