Significance and Use 5.1 Differential scanning calorimeters and differential thermal analyzers are used to determine the transition temperatures of materials. For this information to be meaningful in an absolute sense, temperature calibration of the appar

AMS 2700 does not allow for a user-defined set of passivation parameters (A967 Nitric Methods 4 & 5, Citric Methods 4 & 5) even if they are proven to pass a verification test. This is AMS 2700's greatest procedural difference from ASTM A967. With AMS 2700's larger variety of qualified parameters, one of the sets must be followed.

5.3 This test method is particularly useful for electrical steels coated with inorganic insulating coatings having surface insulation resistivities in excess of 0.3 kΩ·cm 2 [30 kΩ·mm 2] when tested using Test Method A717/A717M (a Franklin current less than 0.02 A). This test method can readily be extended to any range of insulation resistivity …
