(Test Method)Standard Test Method for Flash Point of Cutback Asphalt with Tag Open-Cup Apparatus (Withdrawn 2007)
Standard Test Method for Flash Point of Cutback Asphalt with Tag Open-Cup Apparatus (Withdrawn 2007)
SCOPE
1.1 This test method covers the determination of flash points by the Tag Open-Cup Apparatus of cut-back asphalts having flash points of less than 93°C (200°F). Note 1-Specifications commonly designate the Cleveland Open Cup (ASTM D92-IP36) Method for asphalt cements and cut-back asphalts having flash points above 79°C (175°F). Note 2-This procedure follows in general the procedure outlined in Test Method D1310, but is restricted to cutback asphalt having flash points of less than 93°C (200°F).
1.2 The values stated in SI units are the standard.
1.3 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.
1.4 This standard should be used to measure and describe the properties of materials, products, or assemblies in response to heat and flame under controlled laboratory conditions and should not be used to describe or appraise the fire hazard or fire risk of materials, products, or assemblies under actual fire conditions. However, results of this test may be used as elements of a fire risk assessment which takes into account all of the factors which are pertinent to an assessment of the fire hazard of a particular end use.
WITHDRAWN RATIONALE
This test method covers the determination of flash points by the Tag Open-Cup Apparatus of cut-back asphalts having flash points of less than 93C.
Formerly under the jurisdiction of Committee D04 on Road and Paving Materials, this test method was withdrawn in February 2007.
