All, I need a referral to a lab in North America where I can fly a CSA engineer in to witness the following for clients of ours on occasion. The list server did not let me transmit the table and diagram - if needed let me know and I will forward off-line. Best regards,
Jason L. Chesley CSA International 2210 Justin Trail Alpharetta, GA 30004 P: (678) 992-0134 F: (770) 500-3948 [email protected] www.csa-international.org TEST SUMMARY: Apply currents as per the attached table (based on trade size) for a short time period as per the attached table. The 3 samples of 3 different trade sizes will be provided to the test lab. Each of those samples will be provided with at least 6 inches of conduit from two of the fittings threaded openings. Each of the two lengths of conduit per fitting will have a suitable CSA Certified rigid conduit ground clamp. The current shall be passed between the ground clamps (the leads from your current source can be attached to the ground clamps using wire with minimum AWG size as per the attached Table) and will thus run through the conduit body/fitting. After the current testing continuity shall exist between the parts of the test assembly when measured between the two ground clamps (with the conduit body/fitting in between). An indicating device, such as an ohmmeter or battery-and-buzzer combination, shall be used to determine whether continuity exists. There will be a total of 9 short term tests. TEST PROCEDURE (taken from Tri-National Std. - CSA 18.3/UL 514B/NMX-J-017-ANCE): 8.9 Current test 8.9.1 Three samples of each FITTING shall be tested as described in Clauses 8.9.2 - 8.9.6. A FITTING shall carry the specified current for the time indicated in Table 21. As a result of the test, the FITTING shall not crack or break, and there shall be continuity between the enclosure, FITTING, and raceway following the test. A throat insulator complies where the insulator arcs and burns as a result of the test. 8.9.2 Each FITTING shall be assembled to a minimum 152 mm (6 in) length of raceway of the intended size and an unpainted, plated or unplated, steel enclosure (as shown in Figure 6) or steel plate simulating an enclosure (as shown in Figure 7). A FITTING for metal-clad cable shall be tested with smooth-sheath or continuous-corrugated cable. The thickness of the enclosure or plate shall be as specified in Clauses 8.9.4 and 8.9.5. Note: In Canada, metal-clad (MC) FITTINGS are not recognized. 8.9.3 A LOCKNUT shall be hand-tightened and then further tightened 1/4 turn with a hammer and a standard screwdriver or by an equivalent method. A copper wire lead, not less than 610 mm (2 ft) long, shall be connected: a) to the enclosure by a pressure wire CONNECTOR, and b) to the raceway, 0.8 mm (1/32 in) from the FITTING, by a ground clamp that is sized accordingly. Pressure wire CONNECTORS shall be tightened using the torque specified in Table 22. The test current shall be passed through the wire and assembly. 8.9.4 For 3/8 - 1-1/4 (12 - 35) trade sizes, a FITTING shall be tested with: a) a steel enclosure or plate of thickness 1.35 - 1.40 mm (0.053 - 0.055 in) at the currents specified in Table 21, and b) a steel enclosure or plate of thickness 0.66 - 0.71 mm (0.026 - 0.028 in) at 470 amperes for 4 seconds. A FITTING of the 3/8 - 1-1/4 (12 - 35) trade sizes shall be allowed to be tested with only a steel enclosure or plate of 0.66 - 0.71 mm (0.026 - 0.028 in) thickness when the FITTING is tested at the currents and for the times specified in Table 21. 8.9.5 For 1-1/2 - 6 (41 - 155) trade sizes, a FITTING shall be tested with a steel enclosure or plate of 1.35 - 1.40 mm (0.053 - 0.055 in) thickness in accordance with Table 21. 8.9.6 After having carried the test current, continuity shall exist between the parts of the test assembly when measured between a point on the raceway and a point on the enclosure 6.4 mm (1/4 in) from the FITTING. An indicating device, such as an ohmmeter or battery-and-buzzer combination, shall be used to determine whether continuity exists. {{{Typical Test Configurations/Set-up}}} This message is intended only for the use of the person or organization to which it is addressed, and may contain information that is privileged, confidential and exempt from disclosure under applicable law.
