Active Standard: C1279 - 13
The current C1279 Standard Test Method does not have a section on Calibration and Standardization of the measurement apparatus used, as specified in the ASTM Form and Style Manual, Section A15. The purpose of this revision is to incorporate the existing C1377 Test Method in its entirety, which is a description of the traceable primary calibration procedure used for the Round Robin ILS described in C1279. Also, a description for a secondary calibration procedure that is more convenient for the end user to follow will be added. After these changes are made, a Work Item will be opened for the purpose of withdrawing the current C1377 Test Method, which will no longer be required as a separate standard.
