The user methods in the annex A1 are somehow more simple to do - so, what is the difference to the main method with the pinhole and ILP? For nine different X-Ray tubes with focal spot sizes from 250µm up to 5mm with several tubes of any type the deviaton of both methods were compared.
ASTM E1165 has a confidential interval (red dotted line) and all results are by far within this interval in width and length.
For the Precision and BIAS statement in A 1.7 ASTM requires an evaluation following E691. The user method with the IQI penetrameter hole was tested with more the hundred penetrameter hole images (focal spot length) using different positions and DDAs; different evaluations were done proving the method being constend.
