Description

ASTM G72/G72M-09

Historical Standard: Standard Test Method for Autogenous Ignition Temperature of Liquids and Solids in a High-Pressure Oxygen-Enriched Environment

ASTM G72/G72M

Scope

1.1 This test method covers the determination of the temperature at which liquids and solids will spontaneously ignite. These materials must ignite without application of spark or flame in a high-pressure oxygen-enriched environment.

1.2 This test method is intended for use at pressures of 2.1 to 20.7 MPa (300 to 3000 psi). The pressure used in the description of the method is 10.3 MPa (1500 psi). The test method, as described, is for liquids or solids with ignition temperature in the range from 60 to 425°C (140 to 800°F).

1.3 This test method is for high-pressure pure oxygen. The test method may be used in atmospheres from 0.5 % to 100 % oxygen.

1.4 An apparatus suitable for these requirements is described. This test method could be applied to higher pressures and materials of higher ignition temperature. If more severe requirements or other oxidizers than those described are desired, care must be taken in selecting an alternative safe apparatus capable of withstanding the conditions.

1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

1.6 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.
