Flash and fire point - Cleveland open cup method

12 FLASH AND FIRE POINT - CLEVELAND OPEN CUP METHOD [Pg.193]

The flash and fire points of petroleum products such as bitumens and bituminous binders, having an open cup flash point above 79 C, are determined by the Cleveland open cup apparatus. For fuel oils, the most common test method used is the closed cup procedure that uses the Pensky-Martens apparatus (see ISO 2719 2002 or ASTM D 93 2013). [Pg.193]

The flash point is determined as the lowest temperature at which application of test flame causes the vapour of the test portion to ignite and the flame to propagate across the surface of the liquid under the specified conditions of the test. [Pg.193]

The flash and fire points are useful for safety and security reasons for the avoidance of accidents in case of overheating the bitumen. [Pg.193]

Smoke, Flash, and Fire Point—Cleveland Open Cup Method (Cc 9a-48) determines the temperatures at which fats and oils smoke, flash, or burn. Smoke point determinations sometimes are used to follow degradation of frying oils with use. [Pg.1649]

Flash Point (ASTMD92). The Cleveland open cup method is most commonly used although the Tag open cup (ASTM D3143) is apphcable to cutbacks. Flash point is an indication of fire hazard and the test is frequendy used to indicate whether a given product has been contaminated with materials of lower dash point. [Pg.371]

A. FLASH AND FIRE POINTS BY CLEVELAND OPEN CUP METHOD (COC). The Cleveland Open Cup Apparatus is described as Method 4294 (Sept 1965) of Federal Test Method Standard No 141a... [Pg.462]

The Pensky-Marten apparatus using a closed or open system (ASTM D-93, IP 34, IP 35) is the standard instrument for flash points above 50°C (122°F), and the Abel apparatus (IP 170) is used for more volatile oils, with flash points below 50°C (122°F). The Cleveland open-cup method (ASTM D- 92, IP 36) is also used for the determination of the fire point (the temperature at which the sample will ignite and bum for at least 5 s). [Pg.121]

The fire point is the temperature to which the product must be heated under the prescribed test conditions to cause the vapor-air mixture to bum continuously on ignition. The Cleveland open cup method (ASTM D-92, IP 36) can be used to determine both flash and fire points of lubricating oils, and the Pensky-Martens closed (ASTM D-93, IP 34) and open (IP 35) flash points are also widely used. [Pg.283]

Note Flash points are determined by the ASTM Pensky-Martens Closed Cup Method and fire points by the ASTM Cleveland Open Cup Method. [Pg.420]

Cleveland open cup is used to determine flash and fire points of liquids with flash point above 79°C and below 400°C, such as plasticizers. Standard gives the methods of determination using manual and automatie Cleveland open cup apparatus. About 70 ml of test liquid is heated first rapidly then slowly on approaching an expected flash point. Test flame is apphed to surface to ignite vapors. Test flame is natural or bottled gas flame (full description included in the standard). Test flame is apphed first when the temperature is 28°C below expected flash point and then in 2 C intervals.

ASTM D92 Test Method for Flash and Fire Points hy Cleveland Open Cup... [Pg.92]

The lowest temperature of a flammable liquid at which it gives off sufficient vapor to form an ignitable mixture with the air near the surface of the liquid or within the vessel used. The flash point has been commonly determined by the open cup or closed cup method (ASTM D 56, Standard Test Method for Flash Point by Tag Closed Cup Tester, ASTM D 92, Standard Test Method for Flash and Fire Points by Cleveland Open Cup Tester, ASTM D 93, Standard Test Method for Flash Point by Pensky-Martens Closed Cup Tester ASTM D 3278, Standard Test Method for Flash Point of Liquids by Small Scale Closed Cup Apparatus, ASTM D 3828, Standard Test Method for Flash Point by Small Scale Closed Cup Tester), but recent research has yielded higher and lower flash points depending on the surface are of the ignition source.
