5.  DETAILED REQUIREMENTS

5.1  Test methods.  Standard procedures for testing and evaluating operational shields to assure compliance with applicable design criteria are specified in the following individual test methods.  In order for a shield to be acceptable, the shield shall be tested with the munition(s) for which it was designed under environmental conditions simulating the actual operation and shall have successfully met the criteria in test methods 101 or 102, 201, and 301.

6.    NOTES

(This section contains information of a general or explanatory nature that may be helpful but is not mandatory)

6.1  Intended use.  This  standard  defines the minimum  criteria  necessary to design an operational shield which will protect personnel and assets from thermal, pressure and fragmentation hazards resulting from  an accidental or intentional  detonation of ammunition or explosives; and identifies methods  for testing prototype operational shields to assess the degree to which they  meet  the protection criteria  specified.

6.2 Acquisition requirements. Acquisition documents should specify the following:

a.   Title, number, and date of the standard.

b.   The design activity should submit a test plan as specified for review and approval before conducting any testing.  The test plan should specify those test methods contained herein which are applicable to the design criteria.  At the conclusion of the test a report documenting test results should also be submitted.

6.3  Documentation.

6.3.1  Test plan.  A test plan should be prepared by the testing activity prior to performing any test and submitted for review and approval as specified in the contract or order.  The test

plan should include, as a minimum:

a.  Statement of Purpose, including pertinent background information.

b.  Outline of the objectives to be achieved by the test.  This section should include a description of the operational shield to be tested, the criteria governing the design and the operational use of the shield.

c.   Procedure  to  be  used  to  achieve  test  objectives,  layout  of  equipment,  location  and purpose  of  instrumentation,  listing  of  data  to  be  recorded  during  the  test,  and  any  special considerations.
