ASTM C686-17

Standard Test Method for Parting Strength of Mineral Fiber Batt- and Blanket-Type Insulation

SIGNIFICANCE AND USE
3.1 Tensile strength is a fundamental property associated with mineral fiber manufacture since it is influenced by the type of fiber, the deposition of fiber, the type and the amount of bonding agent, and the method of curing the resin to form a bonded insulation product. The test is an indication of product integrity and the ability of the product to be successfully handled and applied in the field.
SCOPE
1.1 This test method covers evaluation of strength in tension on mineral fiber batt- and blanket-type insulation products. It is useful for determining the comparative tensile properties of these products, specimens of which cannot be held by the more conventional clamp-type grips. This is a quality control method, and the results shall not be used for design purposes. It is not suitable for board-type products.  
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 and health 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.
