4.6 Methods of inspection.

4.6.1 Materials and construction. Conformance to 3.2 through 3.3.2 and 3.3.4 shall be

determined by inspection of contractor records providing proof or certification that design,

construction, processing, and materials conform to requirements. Applicable records shall

include drawings, specifications, design data, receiving inspection records, processing and

quality control standards, vendor catalogs and certifications, industry standards, test reports, and

rating data.

4.6.2 Defects. Conformance to 3.3, 3.3.3 and 3.5 through 3.7 shall be determined by

examination for the defects listed in table III. Examination shall be visual, tactile, or by

measurement with standard inspection equipment.

4.6.3 Performance. To determine conformance to 3.4, the bulldozer kit shall be installed on

a tank or on a simulated test unit, serviced as specified in 3.3.1 and subjected to the tests

specified herein.

4.6.3.1 Hydraulic operating system. To determine conformance to 3.4.1, the bulldozer shall

be operated throughout all ranges of operation, and checked for system operating pressure,

hydraulic pump flow rate, and engine operating speeds.

4.6.3.2 Controls and linkage. To determine conformance to 3.4.2, the bulldozer shall be

operated and the controls and linkage shall be checked for functional requirements.

4.6.3.3 Safety relief valve. To determine conformance to 3.4.3, the bulldozer shall be

operated in such a manner to cause the relief valve to function.

4.6.3.4 Digging depth. To determine conformance to 3.4.4, the bulldozer shall be operated

as specified and checked for digging depth and floating at ground level.

4.6.3.5 Rate of lift. To determine conformance to 3.4.5, the bulldozer shall be operated and

the rate of lift for the moldboard shall be checked for all engine speeds shown in table I.

4.6.3.6 Environmental.

4.6.3.6.1 High temperature. To determine conformance to 3.4.6.1, the bulldozer shall pass

the tests specified in 4.6.3.1 through 4.6.3.5 during exposure to a temperature of 115 + 5�F.

Subsequently, the bulldozer shall be returned to the room ambient conditions specified in 4.3 and

shall pass the tests specified in 4.6.3.1 through 4.6.3.5.
