ASTM F1868 - 23
ASTM International (ASTM)
Title

"Standard Test Method for Thermal, Evaporative Resistance and Total Heat Loss Measurements of Clothing Materials Using a Sweating Hot Plate"

Description

This test method covers the measurement of the thermal resistance, evaporative resistance, and total heat loss under steady-state conditions of fabrics, films, coatings, foams, and leathers, including multi-layer assemblies, for use in clothing systems.

Standard Type(s)
Test Method

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.

Personal Protective Equipment
Body Protection

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
