42、rform any of the inspections set forth in the specification where such inspections are deemed necessary to assure sup- plies and services conform to prescribed requirements. 4.2 Classification of tests - The inspection and testing of actuators shall be asfollows: (a) Qualification tests - Qualificat

43、ion tests are those tests performed on samples submitted as qualified products to determine that the item meets all the requirements of this specification. (b) Acceptance tests - Acceptance tests shall be per- formed on actuators which have been submitted under contract to determine conformance of t

44、he product with requirements set forth in the specifica- tion prior to acceptance. 4.3 Qualification tests - 4.3.1 Qualification test sample - The qualification test sample shall consist of3actuators upon which qualification is desired. The manu- facturer shall furnish all samples 4.3.2 Tests - The

45、qualification tests shall consist of all the tests of this specification as described under section on test methods (4.6). The tests shall be conducted on each of the three actuators in the sequence as shown in table I. 4.3.3 Electric motor tests - When electric motors are con- structed integrally i

46、nto the actuator, all environmental life tests con- duced on the assembled actuator are applicable to the motor also, addition, motor specification tests such as commutation, dielectric strength, brush life, locked rotor protection, etc., which are not included in the required actuator testing, shal

47、l be conducted on the motor, Somp4mprovision of duty cycle or other operating conditions may be necessary to permit de- termination of all necessary motor characteristics since the specific motor requirements must meet the actuator specification requirements as well as the motor Specification requir

48、ements. Procuring activity approval of the proposed test program shall be obtained prior to initiation of the testing.
