26 MechanIsm Endurance Test
26.1 After being subjected to 100.000 cycles of endurance in accordance with 262, a retention tester shall demonstrate performance as intended and shall be within the specified limits of accuracy as determined by 25.3.
26.2 Each line blade or blades and grounding pin of three representative retention testers that have successfully completed the calibration and accuracy test In Calibration and Accuracy, Section 25, is to be subjected to 100.000 cycles of endurance at a rate of riot more than 12 cycles per minute. Another rate may be specified if agreeable to all concerned. Each retention tester is to be fixed in position while a linkage displaces each blade o pin 25 percent of the overall bLade extension.
27 Security of Blades
27.1 Each retention tester that has successfully completed the Mechanism Endurance Test, Section 26, shall also comply with the Security of Blades Test. Section 15. The 20 lb (9.1 kg) weight is to be applied gradually until each blade or pin under test is fully extended. In determining compliance with the 3’32 inch (2.4 mm) total displacement requirement, any displacement that is part of the proper operation of the device is to be disregarded.
28 Crush Test
28.1 A retention tester that has successfully completed the test in Calibration and Accuracy, Section 25, is to be subjected to the Crushing Test, Section 16. After completion of the test, the tester shall demonstrate pertonnance as intended and shaK be within the specified limits of accuracy as determined by 25.3.
29 Drop Test
29.1 A retention tester that has successfully completed the test in Calibration and Accuracy, Section 25, is to be subjected to the Drop Test, Section 18. After being tested in accordance with that section. the tester shall demonstrate performance as intended and shall be within the specified limits of accuracy as determined by 25.3.
30 Blade Wear Test
30.1 After being subject to 100,000 cycles of insertion into and removal from a receptacle, a blade or grounding pin shall not exhibit more than 0.001 inch (0.025 mm) of wear within the “wiped” area of the blade.
Exception: Solid steel line blades and grounding pins need not be subyected to wear conditioning.
30.2 Each of 3 line blades and grounding pins is to be subjected to 100.000 cycles of insertion into and removal from a receptacle. For testing purposes, receptacles of the configurations that comply with the Standard for Attachment Plugs and Receptacles. UL 498, mentioned in 11.4(b) may be used to expose blades to wear conditioning. Each receptacle contact is to exert a minimum force of 8 ounces (2.22 N) onto each blade or pin under test and is to be checked at least twice a day to determine that at least the minimum force is maintained throughout the test. If the force is determined to be less than 8 ounces, the receptacle is to be replaced.
33.11 The calibration tool mentioned in 11.10 shall be permanently marked to designate the testing device with which it is intended to be used. Each retention tester shall be permanently marked to indicate the tool to be used when conducting periodic calibrations along with the recommended intervals at which checks should be conducted.
33.12 A voltage presence indicator shall be permanently marked with the following or equivalent wording:
‘Verify proper operation on a known source before use or taking action as a result of the indications of the device or, a positive means (visual or audible) to indicate the unit is operating properly must be provided. This indication or operation shall be easily distinguishable from other operating modes, In addition, the accompanying documentation must state that the operator needs to verify proper operation before use cx taking action as a result of the indications of the device.”
INSTRUCTIONS
34 General
34.1 A retention tester shall be provided with instructions indicating the proper technique for removal of the tester from the outlet under test, the proper use of the calibration tool, and the action to be taken it the calibration tool indicates that the tester is no longer calibrated.
