ASTM C516-19 + Redline

1.1 This specification covers the composition and physical properties of expanded or exfoliated vermiculite loose-fill insulation. The specification also includes the testing procedures by which the acceptability of the material shall be determined. These testing procedures deal primarily with material performance in the temperature range associated with the thermal envelope of buildings; however, the commercially usable temperature range for this insulation is from –119 to 850°F (–84 to 454°C). Refer to manufacturer's instructions for specialized applications.
