1. (a) Each user subject to this article, as specified in section 30305(a)(1), who develops clinical radiographs for diagnostic purposes with automatic film processors for other than mammographic, dental, or veterinary use, shall assure all of the following:

   1. (1) Each processor used to develop clinical radiographs is adjusted and maintained to meet the manufacturer's processing specifications for the highest speed radiographic film used clinically.

   2. (2) Measurements are performed each day before clinical radiographs are processed, so as to determine that the processor is operating within the following limits:

      1. (A) The base-plus-fog density is within plus 0.05 of the operating level established with the highest speed radiographic film used clinically;
      2. (B) The mid-density is within plus or minus 0.15 of the operating level established with the highest speed radiographic film used clinically; and
      3. (C) The density-difference is within plus or minus 0.15 of the operating level established with the highest speed radiographic film used clinically.
   3. (3) Tests are performed at intervals not to exceed three months to determine that the residual fixer level retained in clinical radiographic films is not more than 5.0 micrograms per square centimeter.
   4. (4) Tests are performed at intervals not to exceed six months to determine that the optical density attributable to darkroom fog is not more than 0.05 when the highest speed of each type radiographic film used clinically, which has a mid-density of no less than 1.20 optical density, is exposed on the counter top for one minute under typical darkroom conditions with the safelight on.
   5. (5) For any test result falling outside the criteria specified in this section, the problem is identified and corrective action is taken before clinical radiographs are processed.
   6. (6) Records of the tests specified in this section, including the problems detected, corrective actions taken, and the effectiveness of those corrective actions, are maintained for at least one year from the date the test was performed.
