(Test Method)Standard Test Methods for Thickness and Density of Blanket or Batt Thermal Insulations
Standard Test Methods for Thickness and Density of Blanket or Batt Thermal Insulations
SIGNIFICANCE AND USE
4.1 Proper measurements of thickness and density of blanket or batt insulations are essential for determining thermal insulation properties. For a particular batt or blanket product, thickness and density are usually directly related to thermal insulating value.
4.2 These test methods are of significant value in manufacturing quality control, to ensure that claimed insulation values of products are maintained.
SCOPE
1.1 These test methods cover the determination of thickness and density of flexible, felted, or woven thermal insulating blankets, rolls, or batts composed of fibrous materials, with or without surface covering or reinforcement.
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.
