6 Info Tests 6.2 Info Test conditions Info Drop and impact The power supply shall be provided with installation instructions stating that the supply circuit for the system shall be protected by a ground fault circuit interrupter (GFCI) of the Class A type, unless GFCI is an integral part of the power supply. Ambient temperature Table 6 is based on a room ambient temperature of 25 C. Tests may be conducted with an ambient temperature between 10 and 40 C. Additionally, a power supply intended for outdoor use shall be tested with an ambient temperature between 35 C to 40 C if the ambient temperature specified by the manufacturer is higher than the temperature limits. If the manufacturer s specified ambient temperature is lower than the temperature limits, the specified ambient temperature shall be used. Prior to the drop and impact tests, a polymeric enclosure of a power supply suitable for outdoor use shall be conditioned to 37.5 C ± 2.5 C for 3 h. If the manufacturer s specified ambient temperature is lower than 40 C, the specified ambient temperature shall be used. Securement of removable, folding, or retractable blades Folding or retractable blades In addition to the blade retention tests specified in Clauses and , the blades shall be subjected to an endurance test of 6,000 cycles. Each cycle shall consist of folding or retracting the blades to its closed or recessed position and then extending it to its position of normal use. Removable blades The blades shall be subjected to 6000 cycles of attachment and re-attachment. Blade test conclusion At the conclusion of each of the tests specified in Clause or above, the power supply shall a) not have any exposed live parts; b) comply with the blade retention test of Clause 6.10; c) not have any damage to the blade securement means of the power supply enclosure; d) not have any deformation to the power supply enclosure that will result in a risk of electric shock; e) not have any dislodgement or displacement of any internal wiring and/or components that will result in a risk of electric shock or fire hazard; and f) remain fully operational. 6

7 Compression (rod) The enclosure shall be subjected to a force of 90 N for a period of 1 min. No live parts shall be made accessible as the result of this test and no condition shall be produced which would increase the risk of electric shock of the power supply. The force specified in Clause shall be applied through the axis of a 12.7 mm diameter metal rod having a flat contact end with the edge rounded to a radius of 0.8 mm to eliminate sharp edges. The axis of the rod shall be perpendicular to the surface under test and the force shall be increased to 90 N over a period of 5 s. Note: During the test specified in Clause , the power supply is to rest on a flat surface in any convenient position. At the completion of the test specified in Clause , the power supply shall be subjected to the dielectric withstand test described in Clause 6.5. Rain A power supply marked for outdoor use shall be subjected to the rain test specified in CAN/CSA-C22.2 No. 94.2, when it is mounted and positioned in the worst-case scenario as intended. The test shall be conducted using water with a resistivity of 200 ohms-meter. The water resistivity shall be obtained by the addition of sodium chloride (commontable salt) to tap water. Distilled water shall not be used. The rain test shall be repeated on other sides of the enclosure of the power supply as necessary unless the construction is such that a test on one side is representative of a test on another side. Following the rain test specified in Clause , the power supply shall be subjected to the following tests: a) leakage current test specified in Clause 6.6. The test shall be discontinued when the leakage current stabilizes; and b) dielectric strength test specified in Clause 6.5. Water immersion 7

8 A power supply suitable for outdoor use shall be conditioned by operating at room temperature for 3-1/2 h. The power supply shall then be de-energized and immediately immersed in at least 0.3 m of water. The temperature of the water, before immersion, shall be 5 C or less. The power supply shall remain submerged for 4 h. At the end of the immersion period, the power supply shall be removed from the water and subjected to 2 additional cycles of operation and immersion. Between each cycle, the power supply shall be placed in a dry location at room temperature for approximately 16-1/2 h. The power supply shall be inspected immediately after the third immersion for evidence of water entry. Following the water immersion test above, the power supply shall be subjected to the following tests: a) leakage current test specified in Clause 6.6. The test shall be discontinued when the leakage current stabilizes; and b) dielectric strength test specified in Clause 6.5. UV Exposure Conditioning Unless the enclosure material has been evaluated for deterioration of impact strength after weathering, in accordance with CAN/CSA-C22.2 No. 0.17, Clause 5.9, the power supply suitable for outdoor use shall be subjected to weathering test specified in Clause 5.9 of CSA CAN/CSA-C22.2 No. 0.17, followed by the test specified in Clause After the UV exposure conditioning test, the test samples shall fulfil the requirements specified in Clause CUSTOMERS PLEASE NOTE: This Table and column Verdict can be used in determining how your current or future production is or will be in compliance with new/revised requirements. 8
