VERIFICATION 4.1 Classification of inspections. The inspection requirements specified herein are classified as follows: a. Conformance inspec
42、tion (see 4.2) 4.1.1 Inspection conditions. Unless otherwise specified in the contract or purchase order (see 6.2), all inspections shall be performed under the following conditions: a. Temperature: Room ambient (65 to 95F) b. Altitude: Normal ground c. Humidity: Room ambient to 95 Percent relative,
43、 maximum. 4.2 Quality conformance inspection. Quality conformance inspection shall consist (at a minimum) of the examinations and tests specified in 4.2.2 and 4.2.3. When specified, items of inspection shall be serialized and inspection data traceable to a specific serial number. The requirements sp
44、ecified are the minimum needed to insure the quality of the rocket catapult. Based upon the manufacturers process or the state of material, additional inspections may be required. The absence of any inspection requirements in the specification shall not relieve the contractor of the responsibility o
45、f ensuring that all products or supplies submitted to the government for acceptance comply with all the requirements of the contract. When specified, sampling inspection is an acceptable practice to ascertain conformance to requirements; however, it does not authorize submission of known nonconformi
46、ng material, either indicated or actual, nor does it commit the Government to accept nonconforming material. 4.2.1 Sampling. One hundred percent examination shall be performed for all examinations of 4.2.2 unless otherwise specified. Sampling for tests shall be as specified in 4.2.3. 4.2.2 Quality c
47、onformance examination. Quality conformance examinations for major and minor characteristics shall be performed in accordance with tables II through X. Classification designations are in accordance with DOD-STD-2101. All defective material shall be removed from the lot. The roughness comparison spec
48、imens prescribed in ASME B46.1 shall be used as a basis of comparison for surface roughness determination. Any component with a critical defect shall be rejected.
