ASTM C1374-03

Standard Test Method for Determination of Installed Thickness of Pneumatically Applied Loose-Fill Building Insulation

SIGNIFICANCE AND USE
This test method was designed to give the manufacturer of loose-fill insulation products a way of determining what the initial installed thickness should be in a horizontal open attic for pneumatic applications.
The installed thickness value developed by this test method is intended to provide guidance to the installer in order to achieve a minimum mass/unit area for a given R-value.
For the purpose of product design, testing should be done at a variety of R-values. At least three R-values should be used: the lowest R-value on the product label, the highest R-value on the product label, and an R-value near the midpoint of the R-value range.
Note 1—For quality control purposes, testing may be done at one R-value of R-19 (h×ft2×°F/Btu) or higher.
Specimens are blown in a manner consistent with the intended installation procedure. Blowing machine settings should be representative of those typically used for field application with that machine.
The material blown for a given R-value as part of the installed thickness test equals the installed mass/unit area times the test chamber area. This mass can be calculated from information provided on the package label at the R-value prescribed.
SCOPE
1.1 This test method covers determination of the installed thickness of pneumatically applied loose-fill building insulations prior to settling by simulating an open attic with horizontal blown applications.
1.2 This test method is a laboratory procedure for use by manufacturers of loose-fill insulation for product design, label development, and quality control testing. The apparatus used produces installed thickness results at a given mass/unit area.
1.3 This test method is not the same as the design density procedures described in Test Methods C 520 or Specifications C 739 or C 764.
1.4 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are provided for information only.
1.5  responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
