"Standard Test Method for Measuring the Thermal Insulation of Clothing Using a Heated Manikin "
This test method covers the determination of the insulation value of clothing ensembles. It describes the measurement of the resistance to dry heat transfer from a heated manikin to a relatively calm, cool environment.
A definitive procedure that produces a test result: Examples of test methods include, but are not limited to: identification, measurement, and evaluation of one or more qualities, characteristics, or properties. A precision and bias statement shall be reported at the end of a test method.
All items of clothing and/or accessories (whether or not detachable) designed and manufactured to provide specific protection. This includes bullet-proof clothing, general protective clothing and full body ensembles that protect from cuts, radiation, temperature extremes, hot splashes from molten metals and other hot liquids, potential impacts from tools, machinery and materials and hazardous chemicals. Examples of body protection include laboratory coats, coveralls, vests, jackets, aprons, surgical gowns and full body suits
- Environmental protective clothing
- Flame and Thermal
This test method can be used to quantify and compare the insulation provided by different clothing systems. For example, variations in the design and fabric used in component garments can be evaluated. The effects of garment layering, closure, and fit can be measured for clothing ensembles. The insulation values for ensembles can be used in models that predict the physiological responses of people in different environmental conditions. Please see the full standard for complete details
