Where a nationally recognized standard exists, the coating shall be applied in accordance with that standard 4.6 Workmanship: Cable management systems shall be free from burrs, fins, or other sharp projections that would be liable to cause damage to the cables. 5. Marking 6. Tests 5.1 Marking on Product: Each straight section of the system and each fitting shall be marked in a permanent and visible manner with the following: (a) Manufacturer s name, trade name or other recognized symbol of identification; (b) The minimum equivalent cross-sectional area in accordance with the Canadian Electrical Code (CEC), Part I of the cable management systems used as equipment grounding (or bonding) conductors (on systems in compliance with the requirements of Clause 6.4), or the statement: CAUTION: The system shall not be used as the bonding to ground means. Alternative means shall be provided per CEC, Part I (on systems not in compliance with the requirements Clause 6.4); 5.2 Product Information: The manufacturer shall provide, in readily available catalog form, or, with each shipment of cable management system, a set of instructions, which shall include the following information: (a) A table or chart clearly indicating the maximum allowable simple beam loading in kilograms per linear metre and/or lb/linear foot and the maximum recommended distance in metres or feet between supports for each loading; and (b) Installation guidelines. 6.1 Mechanical Loading General: Straight sections of cable management systems supported as specified in Clauses and shall be capable of being loaded in accordance with Clauses to without suffering greater residual deflection than specified in Clause Test Specimen: The test specimen shall be a simple beam span, with free unrestrained ends. Span lengths shall be as specified, with a tolerance of ±40 mm (1-1/2 in). An unspliced straight section of the greatest width shall be used in each test.

8 with the load for which the specimens are to be tested. (See Tables 1 and 2) Support Method: The specimen shall be oriented as intended for use and supported at each end in a horizontal position by a steel bar 300 mm (12 in) wide and 200 mm (8 in) high with a V notch cut in its bottom. The V notch shall rest on a round steel bar 25 mm (1 in) in diameter Loading Material: Loading material shall be steel strips, not exceeding 3000 mm (10 ft) in length, 100 mm (4 in) in width and 3.2 mm (1/8 in) in thickness Minimum Test Load: The minimum test load to be applied shall be determined in accordance with the following formula: Total minimum test load = 1.5 x L x W where W = rated load in kilograms per metre (or in pound per foot), L = span length in metres (or in feet), 1.5 is a safety factor Load Arrangement: The loading material shall be uniformly distributed for the length and width of the specimen, except that the loading material shall not be closer than 13 mm (1/2 in) nor further than 25 mm (1 in) from the innermost elements of the sides. It shall not bridge transversely. All loading material shall be placed between the test supports without overhanging Load Application: The specimen shall first be loaded to the 10% of the minimum requirement of Clause The vertical deflection of the straight section shall be measured at three points along the line midway between the supports and at right angles to the longitudinal axis of the specimen. The three points of measure shall be under each side rail and at the center of the specimen. This measurement shall be known as the initial deflection. The loading shall then be continued until all of the rated load (L x W) is applied. The deflection may be measured in the same manner as for the initial deflection. The loading shall then be continued until the total minimum test load has been applied. The maximum deflection shall be measured in the same manner as indicated above. The total load shall then be removed from the tray. After a period of 15 min the vertical deflection shall then be measured in the same manner as previously used. This measurement shall be known as the residual deflection. The specimen may then be loaded until it collapses, and the value of the destruction load only shall be recorded. Note: The information concerning the load at collapse point is optional. The total weight of the loading material, prior to addition of the incremental weight, that causes the destruction, shall be considered to be the destruction load. The rated load capacity of the cable management system shall be the destruction load divided by a safety factor of 1.5. Page 6 of Residual Deflection: Two specimens of the same size shall be tested under the same conditions and the residual deflection at each point of measurement shall be averaged. Where the residual deflection for either specimen is equal to or exceeds I:\WGM4\DOC_CTRL\NOTICE\8\mc

9 6.2 Protective Coating 80% of the initial deflection and, in addition, deviates from the average by more than 10%, then two more specimens shall be tested. The average of the three highest values, at the point of measurement, of the four specimens shall be regarded as the final result Zinc Coating: Zinc coatings where applicable shall be such that a specimen with an electro plating finish does not show a fixed deposit of copper after two 1 min immersions in a standard copper sulfate solution, and a specimen with hot-deep galvanized finish does not show a fixed deposit of copper after four 1 min immersions in a standard copper sulfate solution. The copper sulfate solution and the procedure used in this test shall be in accordance with ASTM Standard A 239 and B 633. Specimens cut from potions of the straight sections should be at least 100 mm (4 in) long. The surface within 6 mm (1/4 in) from the cut edges shall be disregarded when making observations for the copper deposit Other Coatings: Other coatings may be applied as appropriate for the application. The coating shall be applied in accordance with the applicable national or ASTM standard. 6.3 Supplementary Coatings: At the option of the manufacturer, a supplementary coating may be applied to the cable tray systems, but such coating does not fall within the scope of this Standard. 6.4 Bonding Each specimen shall consist of two 600 mm (24 in) minimum length of straight sections plus mechanical connecting means A current of 30 A dc shall be passed through the assembly, and the resistance measured between two points located 1.5 mm (1/16") on each side of the connector. The net resistance of the connection shall be less than ohms as computed from the measured voltage drop and current passing through the specimen, at an ambient temperature of C (60-95 F).
