Update revisions by adding a clarification on unit values used in the standard, and update the fire caveat. Item 1: Concurrent For ASTM C916: Standard Specification for Adhesives for Duct Thermal Insulation Add new Section 1.2 addressing unit values used in the standard. 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. Item 2: Concurrent For ASTM C916: Standard Specification for Adhesives for Duct Thermal Insulation Replace current 7.7.1 which is an outdated fire caveat to the current fire caveat approved by E5 Fire Standards. Current Wording: 7.7.1 This test should be used to measure and describe the properties of materials, products, or assemblies in response to heat and flame under controlled laboratory conditions and should not be used to describe or appraise the fire hazard or fire risk of materials, products, or assemblies under actual fire conditions. However, results of this test may be used as elements of a fire risk assessment which takes into account all of the factors which are pertinent to an assessment of the fire hazard of a particular end use. Proposed Wording: 7.7.1 This standard is used to measure and describe the response of materials, products, or assemblies to heat an flame under controlled conditions, but does not by itself incorporate all factors required for fire-hazard or fire-risk assessment of the materials, products, or assemblies under actual fire conditions.
