ASTM C1086-20

Standard Specification for Glass Fiber Mechanically Bonded Felt Thermal Insulation

ABSTRACT
This specification covers glass fiber unsupported needled felt binder-free thermal insulations. This material is used as the thermal insulation component in the fabrication of insulation systems for use on machinery and equipment, such as steam turbines, boilers, boiler feed pumps, and piping at specified elevated temperatures. Thermal insulations should adhere to the following physical requirements: apparent thermal conductivity, hot surface performance, tensile strength, non-combustibility, and dimensions (nominal thickness, mass per unit area, length, and width).
SCOPE
1.1 This specification covers glass fiber unsupported needled felt (mechanically bonded) binder-free insulation for thermal insulation. This material is used as the thermal insulation component in the fabrication of insulation systems for use on machinery and equipment, such as steam turbines, boilers, boiler feed pumps, and piping at temperatures from ambient up to 1200°F (650°C).  
1.2 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.  
1.3 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.  
1.4 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.
