This standard prescribes the methods of test for preformed thermal insulating materials in the form of blocks, slabs, and pipe sections. It covers essential physical and mechanical tests including bulk density, compressive strength, moisture content, and water absorption to evaluate insulation quality.
Describes methods of test for preformed thermal insulating materials.
Quick Reference Values
Standard test temperature27 ± 2 °C
Standard relative humidity65 ± 5 %
Typical compressive deformation limit10%
Key Formulas
Bulk Density (ρ) = Mass (m) / Volume (V)
Moisture Content (%) = ((W1 - W2) / W2) * 100
Practical Notes
Proper conditioning of samples in standard laboratory conditions is crucial before determining moisture content or dry density to avoid erratic results.
Ensure uniform load distribution across the testing surface area when determining compressive strength.
Thermal conductivity is not covered in this specific standard and must be evaluated separately as per IS 3346.
