Full Description

1.1This test method covers a means for the discrimination between gases, which will ignite or not ignite when impinged on a hot surface when that surface is heated to 800C 5C (1472F) for a period of 2min in a non-confined environment.

1.2This test method may be applied to any non-pyrophoric substance that is a gas or liquefied gas at ambient temperature and pressure.

1.3This test method should be used subject to the limitations that no single fire hazard property such as flash point, auto-ignition temperature (AIT), or the performance under the conditions of the present method shall be used to describe or appraise the fire hazard or fire risk of a material, product, assembly, or system under actual fire conditions. Fire hazard properties measured under controlled laboratory conditions may nevertheless be employed to describe properly the response of materials, products, assemblies, or systems under said controlled conditions. Properties measured under controlled laboratory conditions may be used as elements of hazard or risk assessment only when such assessments takes into account all of the factors that are pertinent to the evolution of the fire hazard of a given situation.

1.4This standard is used to provide a quantitative measure of a gass or liquefied gass realistic surface ignition temperature in a non-quiescent environment.

1.5The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.

1.6This 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Section 9.

1.7This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
