ASTM C167 – Standard Test Methods for Thickness and Density of Blanket or Batt Thermal Insulations
Description:
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.
