1、Designation:D817518Standard Test Method forFinite Flash Point Determination of Liquid Wastes byPensky-Martens Closed Cup Tester1This standard is issued under the fixed designation D8175;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision
2、,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.INTRODUCTIONThis flash point test method is a dynamic test method that depends on specified rates of heating tobe able to
3、 meet the precision of the test method.The rate of heating may not in all cases give theprecision quoted in the test method because of the low thermal conductivity of some materials.Flash point values are a function of the apparatus design,the condition of the apparatus used,andthe operational proce
4、dure carried out.Flash point can,therefore,only be defined in terms of a standardtest method,and no general valid correlation can be guaranteed between results obtained by differenttest methods or with different test apparatus.This test method,and Test Method D8174,are used to determine the flash po
5、int of liquid wastes.These procedures are primarily derived from Procedures A and B of Test Methods D93(EN ISO2719),and are informally known as Pensky-Martens.1.Scope1.1 This test method covers the procedure for a finite flashpoint test,within the range of 20 to 70 C,of liquid wastesusing a manual o
