MIL-STD-2106A(SH)
5. DETAILED REQUIREMENTS
5.1 Test stages. Testing of shipboard equipment and systems is conducted in stages with each progressive stage building upon the results of testing at prior stages. Thus, overall system integrity is based upon the results of all required stages of testing. The seven discrete stages of industrial testing are defined in Appendix A with examples provided for stages two through seven. This standard is applicable to tests in stages two through seven.
5.1.1 Grooming. General equipment grooming, alignment, and adjustments are considered to be part of the industrial work and are not normally included in the test procedure.
5.2 Engineering process. The engineering process specified in this section provides a structured method for the development of test procedures that will demonstrate the initial acceptable performance of equipment and systems in ships from test stages two through seven. This process is depicted in block form on figure 2 and consists of the following steps:
a. Equipment/system definition b. Test element identification
c. Test element selection
d. Test stage determination e. Redundancy analysis
f. Test element grouping
g. Test outline preparation
h. Test outline review and approval i. Test procedure development
j. Test number/test title assignment
k. Test procedure review and approval l. Test procedure verification
m. Final test procedure development
5.2.1 Equipment and system definition. The initial step in the development of test procedures is to identify the hardware to be tested. This hardware is then classified as an equipment to be tested at stage three or a system to be tested at stages four and five. Classifying the hardware as a system does not imply that stage three tests will not also be required, and classification as an equipment does not imply that stages four and five tests will not be required.
The equipment or system classification is based on previous test experience and intimate knowledge of the hardware and the ship environment. The following factors shall be considered in making this determination:
a. Hardware configuration and packaging
b. Functional compatibility of the hardware packages c. Complexity of the individual hardware packages
d. Complexity of the larger system of which this hardware is a part, or the complexity of the components that comprise this hardware packaging
e. Shipboard test conditions that favor testing at one stage over another
Hardware classified as equipment or system shall be defined in a breakdown diagram. When specified (see 6.2), breakdown diagrams shall be submitted.
5.2.1.1 Breakdown diagram content. The equipment or system to be tested shall be represented by one or more functional blocks enclosed in heavy or double lines. Each block shall represent an independent functional unit. External equipment or systems that interface with the equipment or system to be tested shall also be shown.
External and internal interfaces shall also be shown on breakdown diagrams.
