3. Definitions
For the purposes of this standard, the following terms and definitions apply. IEEE 100 (B12] should be refer.
enced for terms not defined in this clause.
3.1 carbon steel: A steel containing only residual quantities of elements other than carbon, except thoseadded for deoxidation or to counter the deleterious effects of residual sulfur. Silicon is usually limited toabout 0.60%, and manganese to about 1.65%. Also termed plain carbon steel, ordinary steel, straight carbonsteel (see Bringas and Wayman (B11]).
3.2 conformance tests: Certain performance tests are conducted to demonstrate compliance with the appli*able standards. The test specimen is normally subjected to all planned routine tests prior to initiation of theconformance test program.
NOTE-The conformance tests may, or may not, be similar to certain design tests. Demonstration of margins (capabili.
ties) beyond the standard requirements is unnecessary.
3.3 design tests: Tests made by the manufacturer to determine the adequacy of the design of a particulatype, or model of equipment, or its component parts to meet its assigned ratings and to operate satisfactorilyunder normal conditions and under special conditions if specified. These tests may be used to demonstratecompliance with applicable standards of the industry
NOTE-Design tests, sometimes called type tests, are made on representative apparatus or prototypes to verify thealidity 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 ensure thatperformance has not been adversely affected. Test data from previous similar designs may be used for current designswhere appropriate. Once made, the tests need not be repeated unless the design is changed so as to modify performance
4. Enclosure design and coating system requirements
4.1 Enclosure design requirements-objective
The objective of this section is to describe design and performance requirements for carbon steel pole-mounted enclosures. Other stringent performance requirements may be needed to ensure long field life in
special or coastal environments.
4.1.1 Accessibility
The enclosure shall be designed such that all exterior surfaces are accessible for proper surface preparationand the application of a uniform amount of the coating materials. Additionally, all exterior surfaces of theenclosure shall be accessible for the purposes of inspection and maintenance of the enclosure over the life ofthe equipment.
4.1.2 Contaminant accumulation
The enclosure shall be designed to shed water and minimize areas where corrosive elements can accumulate.
4.1.3 Welds-surface preparation
All welds shall be treated to prepare the weld area and the heat affected zones for coating. Weld splatter shallbe removed. All welds shall be made in accordance with appropriate industrial welding standards.
4.2 Substrate requirements
The substrate shall be a material that, when coated or otherwise processed, will maintain the structural in-tegrity of the enclosure over the life of the apparatus.
4.3 Coating system requirements
4.3.1 General
All coated surfaces on the exterior of the enclosure that may be exposed to the environments shall be capableof meeting the performance tests required by this standard.
