ASTM F1935-01(2011)
(Test Method)Standard Test Method for Measuring the Headroom of a Backpacking or Mountaineering Tent
Standard Test Method for Measuring the Headroom of a Backpacking or Mountaineering Tent
SIGNIFICANCE AND USE
This test method can be used to quantify and compare headroom of backpacking and mountaineering tents. The measured headroom can be used as a manufacturing standard or a measurement that can be used by consumers to compare the interior height of a variety of tents, or both.
SCOPE
1.1 This test method covers tents for use in the sports of backpacking and mountaineering. It establishes requirements for the testing and marking of tents.
1.2 This test method may contain test methods that do not entirely simulate real life situations. This test method is designed to give reproducible results in a laboratory and thereby a means for product comparison.
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.
