conformance tests: Certain performance tests are conducted to demonstrate compliance with the applicable standards. The test specimen is normally subjected to all planned routine tests prior to initiation of the conformance test program. NOTE—The conformance tests may or may not be similar to certain design tests. Demonstration of margins (capabilities) beyond the standard requirements is unnecessary. 3 design tests: Tests made by the manufacturer to determine the adequacy of the design of a particular type or model of equipment or its component parts to meet its assigned ratings and to operate satisfactorily under normal conditions and under special conditions if specified. These tests are used to demonstrate compliance with applicable standards of the industry. NOTE—Design tests, sometimes called type tests, are made on representative apparatus or prototypes to verify the validity of design analysis and calculation methods and to substantiate the ratings assigned to all other apparatus of basically the same design. These tests may also be used to evaluate the modification of a previous design and to verify that performance has not been adversely affected. Test data from previous similar designs may be used for current designs, where appropriate. Once made, the tests need not be repeated unless the design is changed so as to modify performance. dry film thickness: Thickness of any applied coating(s) measured after curing. enclosure security: The completely assembled apparatus will resist unauthorized entry when tested in accordance with the procedures of this standard. gel coat: The material that provides the inhibition for ultraviolet protection and color to the fiber reinforced plastic (FRP). pad-mounted enclosure: An enclosure containing electrical apparatus, typically located outdoors at ground level where the general public has direct contact with the exterior surfaces of the equipment. 4. Enclosure security 4.1 Galling Steps must be taken in the design and manufacture of enclosures to prevent galling. Two commonly used methods are listed below, but are not specifically required separately or in combination. Alternative methods may be used if proven to be equally effective: a) Use of dissimilar materials in threaded joints such as silicon-bronze with stainless steel, brass with stainless steel, etc. b) Use of anti-seize compounds or materials. 4.2 Test requirements In addition to passing the tests defined in this standard, the construction of pad-mounted enclosure shall comply with the requirements of 4.2.1 through 4.2.9. 4.2.1 Enclosure mounting The bottom edge of the enclosure shall provide for flush mounting on a flat, rigid, mounting surface. 4 4.2.2 Water resistance The enclosure shall restrict the entry of water (other than flood water) into the enclosure so as not to impair the operation of the apparatus inside. 4.2.3 Sharp corners External sharp corners and projections shall be minimized. 4.2.4 Panel assembly Panels shall be fastened or hinged to resist disassembly, breaking, or prying open from the outside with the doors in the closed and locked position. Normal entry shall be possible only with the use of proper access tools. There shall be no exposed screws, bolts, or other fastening devices that are externally removable (with the exception of pentahead bolts provided for extra security) that would provide access to energized parts in the enclosure. 4.2.5 Door hardware Locking bolts and associated threaded receptacles, hinges, and hinge pins shall be AISI 5 type 304 stainless steel or material of equivalent corrosion resistance.
