Anotace textu normy ASTM C1427-25 :

This specification covers the standard for two grades of extruded preformed flexible cellular polyolefin thermal insulation. Physical properties of preformed flexible cellular polyofelin thermal insulation which are mandatory for thermal design are also covered. Properties such as density and coefficient of thermal expansion (CTE) have been deemed nonmandatory for thermal design. The thermal insulation shall comply with physical requirements. Such physical requirements include thermal conductivity, water vapor permeability, and linear shrinkage and shall be determined by test methods specified here.
