Historical Standard: ASTM D5965-96 Standard Test Methods for Specific Gravity of Coating Powders
SUPERSEDED (see Active link, below)
ASTM D5965
1. Scope
1.1 These test methods cover three procedures for determining the specific gravity (see definition) of coating powders, as follows:
| TEST METHOD AFor Testing Coating Powders, Excluding Metallics |
| TEST METHOD BFor Tests Requiring Greater Precision than Test Method A,Including Metallics, Using Helium Pycnometry |
| TEST METHOD CFor Theoretical Calculation Based on Raw Material SpecificGravities |
1.2 Test Method A can be used as a less expensive method with reduced accuracy for determining the specific gravity of coating powders, excluding metallics.
1.3 The ideal gas law forms the basis for all calculations used in the Test Method B determination of density of coating powders.
1.4 Test Method B includes procedures that provided acceptable results for samples analyzed during round robin testing.
1.5 Test Method B uses SI units as standard. State all numerical values in terms of SI units unless specific instrumentation software reports surface area using alternate units. Many instruments report density as g/cm 3 , instead of using SI units (kg/m 3 ).
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
