ASTM E1868-97

Standard Test Method for Loss-On-Drying by Thermogravimetry

SCOPE
1.1 This test method covers a procedure for determining the amount of volatile matter of any kind that is driven off from a test specimen under a specific set of temperature and time conditions. This test method determines only the mass of material lost, not its identity.
