(Specification)Standard Specification for Cellular Melamine Thermal and Sound-Absorbing Insulation
Standard Specification for Cellular Melamine Thermal and Sound-Absorbing Insulation
ABSTRACT
This specification covers cellular melamine thermal and sound-absorbing insulation for use in industrial environments operating within the specified temperature range. Some applications of the thermal insulation materials covered by this standard are subject to building codes for fire performance. A vapor retarder is required when the insulation materials are used for cold surface applications where water vapor condense and may cause a decrease in thermal performance. Open-cell melamine foam is produced when a pentane blowing agent is used to foam a melamine-aldehyde precondensate. Melamine thermal insulation is furnished in three types according to shape and two grades according to facing. The typical facing materials are aluminum foil, aluminized mylar, polyvinylchloride, and polyvinylfluoride. All materials should conform to the required values of oxygen index, specific optical smoke density, surface burning characteristics, density, tensile strength, percent elongation, indentation force deflection, and thermal conductivity.
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 Some uses of thermal insulation materials covered by this specification are 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 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.
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
