(Specification)Standard Specification for Flexible Fibrous Glass Blanket Insulation Used to Externally Insulate HVAC Ducts
Standard Specification for Flexible Fibrous Glass Blanket Insulation Used to Externally Insulate HVAC Ducts
SCOPE
1.1 This specification covers the composition, size, dimensions, and physical properties of flexible fiber glass blanket, ductwrap, used to externally insulate HVAC ducts used for the distribution of condition air with a temperature up to 250oF (121oC).
1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only and may be approximate.
1.3 When the installation and use of thermal insulation materials, accessories, and systems may pose safety and health problems, the manufacturer shall provide the user appropriate current information regarding any known problems associated with the recommended use of the company's products, and shall also recommend protective measures to be employed in their safe utilization. The user shall establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use.
1.4 The following safety hazards caveat pertains only to the test methods, Section 13, in this specification. 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.
