ASTM C1410-98

Standard Specification for Cellular Melamine Thermal and Sound-Absorbing Insulation

SCOPE
1.1 This specification covers the type, physical properties, and dimensions of open-cell melamine foam intended for use as thermal and sound-absorbing insulation for temperatures from -40 to 350°F (-40 to 177°C) in industrial environments.
1.2 The use of thermal insulation materials covered by this specification may be governed by building codes that address fire performance.
1.3 The use of an appropriate vapor retarder is required on cold surface applications where water vapor could condense and cause a decrease in thermal performance. Refer to Practice C755 for selection of vapor retarders. Facings shall be agreed upon between the purchaser and the manufacturer or supplier. This specification addresses the foam alone.
1.4 The values stated in inch-pounds are to be regarded as the standard. The SI units given in parentheses are provided for information only and may be approximate.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
