ASTM F2568-06

Standard Test Method for Measurement of Sleeping Bags

SIGNIFICANCE AND USE
In this context, this test can be used for specifications, design, and quality control. Girth in and of itself is not to be used to predict the thermal properties of a sleeping bag.
SCOPE
1.1 This test method determines the internal girth, the internal length and width, and the external length and width of a sleeping bag under a standardized measurement method.
1.2 The measurement uses a physical measurement method applicable to any location where a flat level surface is provided.
1.3 The values stated in inch-pound units are to be regarded as standard.
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.

and external length and width of sleeping bags.
The external length and width measurements or internal length and width measurements apply to
length and width measurements required for standardized Bedding Labels.
The “girth” (that is, internal circumference) of a sleeping bag refers to the total internal
circumference at specific longitudinal measurement points of a closed sleeping bag. It is a physical
dimension/measurement used for specifications, design, and quality control. Girth in and of itself is
not to be used to predict thermal properties of a sleeping bag.
