Rationale

Clause 10.1.2 states “The total mass of the calorimeter assembly positioned on the sample is 500 ± 5 gm.” The statement is misleading as is made to set the total mass of the calorimeter to 500 ± 5 gm during the assembly instructions as the test sample is being positioned in the apparatus for testing. The total mass specification for the calorimeter should be given in the section describing the construction of the calorimeter assembly for clarity. The proposed revisions to Section 6.1.1, Section 6.5, and Section 10.1 accomplish this.
