ASTM C552-22

Annotation of standard text ASTM C552-22 :

This specification covers the composition, sizes, dimensions, and physical properties of cellular glass thermal insulation. The material shall consist of a glass composition that has been foamed or cellulated under molten conditions, annealed, and set to form a rigid noncombustible material with hermetically sealed cells. The materials shall also be trimmed into rectangular or tapered blocks of standard dimensions. All specimens shall also comply with with qualification requirements such as compressive strength, flexural strength, water absorption, water vapor permeability, thermal conductivity, hot-surface performance, thermal conductivity and surface burning characteristics. These properties shall be determined in accordance with test methods specified herein.
