  • THE CERTIFICATION OF A SECOND SERIES OF FIVE HYDROCARBON MATERIALS FOR THE DETERMINATION OF EQUILIBRIUM FLASHPOINT (TEMPERATURE RANGES -10 TO + 5 DEGREES C)

Abstract

The closed cup flashpoints of five pure hydrocarbon materials (iso-octane, toluene, n-dodecane, n-tetradecane and n-hexadecane) have been determined by equilibrium methods in an interlaboratory exercise, involving twelve laboratories of the European Community member countries and one laboratory of the Commission of the European Communities. The methods used were based on IP303/74 (or ASTM D3278-73; Rapid Tester) and IP304/74 (Abel, Abel-Pensky, Pensky-Martens Cups) with extension to allow equilibrium conditions to be maintained outside the ranges of these methods. As a result, the closed cup flashpoints of these materials by an equilibrium method are certified at the following temperatures: CRM No. Hydrocarbon Equilibrium closed cup flashpoint 83 iso-octane - 9.5 +- 0.5 degrees C 84 toluene + 6.0 +- 0.5 degrees C 85 n-dodecane + 81.0 +- 1.0 degrees C 86 n-tetradecane + 108.0 +- 1.0 degrees C 87 n-hexadecane + 133.5 +- 1.0 degrees C The uncertainties are expressed in terms of the 95 % confidence limits of the mean, rounded up to the nearest 0.5 degrees C. This report describes the experimental details of the interlaboratory measurements and the certification procedure.
