ASTM E1114-92(1997)e1
Historical Standard: ASTM E1114-92(1997)e1 Standard Test Method for Determining the Focal Size of Iridium-192 Industrial Radiographic Sources
SUPERSEDED (see Active link, below)
ASTM E1114
1. Scope
1.1 This test method covers the determination of the focal size of an iridium-192 radiographic source. The determination is based upon measurement of the image of the iridium metal source in a projection radiograph of the source assembly and comparison to the measurement of the image of a reference sample in the same radiograph.
1.2 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.
