D0093-Test Methods for Flash Point by Pensky-Martens Closed Cup Tester

Following reports of the use of a modified lid and cup mechanism by one D93 apparatus manufacturer, a request was made to use ASTM Crosscheck data to statistically assess whether this caused any significant differences to results. Crosscheck data was collected from tests predominately using Procedure B and the modified locking mechanism, covering flash points from 70 to 210C. Multiple sample comparisons were made on the data by a CS94 statistician using scatter plots, and box and whisker plots. A revision was sought to modify the D93 method to allow modified lid and cup locking mechanisms. However it was thought that allowing generic changes could affect the integrity of the method and that a specific research would be a better vehicle to describe the evaluated changes.
