This standard has been approved for use by agencies of the Department of Defense. Scope 1. Requirements expressed in this method are intended to control the reliability or quality of the radio- graphic images, and are not intended for controlling the acceptability or quality of materials or products. It is the responsibility of the user of this standard to establish appro- priate safety and health practices and determine the applica- bility of regulatory limitations prior to use.
Referenced Documents 2. Current edition approved May 15, Published July Originally published as E — 59 T. Last previous edition E — Terminology 3. Direction of Radiation 4. Penetrameters 5. Placement of Penetrameters 6. When weld reinforcement or protruding backing ring is not removed, a shim of the same type of metal as the parent metal shall be placed under the penetrameter to provide the same thickness of material under the penetrameter as the average thickness through the weld.
Shims shall exceed the penetrameter dimensions such that the outline of at least three sides of the penetrameter image shall be visible on the radiograph and the shimmed penetrameter shall be placed so as not to overlap the backing strip or ring. This is to permit equitable evaluation of the penetrameter where diffrac- tion effects may be encountered in the radiography of some cast or weld deposit materials. Number of Penetrameters 7. At least one penetrameter per radiograph, exposed simultaneously with the specimen, shall be used except as noted in 7.
The radiographic density of the penetrameter shall be measured through the body of the penetrameter. If one penetram- eter shows an acceptable sensitivity at the most dense portion of the radiograph and the second penetrameter, placed in accordance with Section 6, shows an acceptable sensitivity at the least dense portion of the radiograph, these two penetram- eters will serve to qualify the radiograph.
Location of Markers 8. These marker positions shall be marked on the part, and the position of the markers shall be maintained on the part during radiog- raphy. Any or all of the following may appear: the name of the inspecting laboratory, the date, the part number, the view, and whether original or subsequent exposure.
