1.1 This guide2 establishes guidelines that may be used for the control and maintenance of industrial radiographic film processing equipment and materials. Effective use of these guidelines aids in controlling the consistency and quality of industrial radiographic film processing.

1.2 Use of this guide is limited to the processing of films for industrial radiography. This guide includes procedures for wet-chemical processes and dry processing techniques.

1.3 The necessity of applying specific control procedures such as those described in this guide is dependent, to a certain extent, on the degree to which a facility adheres to good processing practices as a matter of routine procedure.

1.4 If a nondestructive testing agency as described in Specification E543 is used to perform the examination, the testing agency should meet the requirements of Specification E543.

1.5  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, health, and environmental practices and determine the applicability of federal and local codes prior to use.

1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4.1 The provisions in this guide are intended to control the reliability or quality of the image development process only. The acceptability or quality of industrial radiographic films processed in this manner, as well as the materials or products radiographed, remain at the discretion of the user, or inspector, or both. It is further intended that this guide be used as an adjunct to, and not a replacement for, Guide E94.

4.2 Users of non-classified film systems may use monitoring films as described in 8.3 for activity testing of film processing.

4.3 If required, film system manufacturers provide a conformity statement on the classification of their film types in their processing chemicals for given processing conditions according to Test Method E1815. Users may apply “mixed systems” in which the film manufacturer is different from the manufacturer of the film development chemicals, processing system, and specified development conditions. In this case, see 8.2.2 and Appendix X1.
