MIL-STD-2106A(SH)
5.2.9.1 Testing steps. The Testing Steps section of each test procedure shall provide detailed instructions for test implementation. Each testing step in the test procedure shall be defined and sequenced to ensure that the test procedure can be efficiently performed. The METHOD section of the GENERAL INFORMATION provides the starting point for testing steps development; each test step represents an expansion and detailed explanation of the general approach presented in the METHOD section. In many cases these steps will have been previously developed in other similar test procedures. Testing steps from similar procedures should be examined to determine if they could be modified to fulfill the current requirements. Some potential sources of testing steps are factory acceptance test procedures, maintenance requirement cards, technical repair standards, technical manuals, specifications, standards, and test document repositories. The procedure as written shall be self-contained and not refer to steps, paragraphs, or sections of technical manuals or other publications. When testing steps are being developed or modified and when the optimum sequence is being determined, the following factors should be considered:
a. Economical use of test personnel.
b. Use of standard shipboard test equipment as defined in NAVSEA ST000-AA-IDX-010-PEETE. c. Economical use of support equipment.
d. Minimizing the requirements for external support.
e. Steps must be practical to perform in a shipboard environment.
f. Do not include steps that require adjustment of the equipment under test. Testing steps shall be documented as specified by Appendix B for format and content.
5.2.9.2 Test data recording sheet. The TEST DATA RECORDING sheet provides a place for recording each indication required in the testing steps and provides a clear statement of expected results including applicable tolerances. After the testing steps have been developed, the most critical aspect of test procedure development is to specify the expected results. Data to be used in the establishment of expected results can be found in operational requirements documents, specifications, factory acceptance test criteria, maintenance requirement cards, technical repair standards, and technical manuals; however, the tolerances found in these documents may require modification prior to use in industrial test procedures. The purpose of industrial testing is not to determine if the system or equipment is performing to specification (factory acceptance tests); rather, the purpose is to verify that the system or equipment, as installed, will meet performance requirements for that ship. Therefore, the tolerances used for shipboard industrial testing may be different from those found in specifications or in factory acceptance tests. Performance limits for shipboard industrial testing shall be established such that performance outside these limits would be indicative of one or more of the following factors:
a. Serious degradation in the ability of the system or equipment to perform its intended function.
b. Abnormal or marginal operating condition that may indicate or result in equipment failure or low post-repair reliability or functionality.
c. Inability of the system or equipment to interface properly with other equipment or systems.
These performance limits become the expected results and appropriate tolerances for the EXPECTED RESULTS column of the TEST DATA RECORDING sheet. The format and content for the TEST DATA RECORDING sheet shall be as specified in Appendix B.
5.2.9.3 Test conditions and equipment. After the testing steps have been specified and arranged in the appropriate sequence, the INITIAL CONDITIONS AND SETUP, SHUTDOWN AND SECURING, and TEST EQUIPMENT USED sheets shall be prepared. Format and content guidance for preparation of these paragraphs is included in Appendix B.
5.2.9.4 General instructions. The GENERAL INFORMATION section of the test procedure provides the general instructions relating to the TESTING STEPS section. The general instructions provided by the GENERAL INFORMATION section shall be reviewed and updated prior to preparation of the test procedure to ensure that
these instructions are consistent with the testing steps developed in 5.2.9.1. Safety instructions shall be added to the test procedure in accordance with the format and content requirements provided in Appendix B.
