有限公司提供:
11.7 Crushing test
11.7.1 Except as noted in 11.7.3, a plug with a confifiguration of plug 1-15, 2-15, 5-15 or 6-15 shall be capable of withstanding for 1 minute a crushing effort of 334 N (75 lbf) applied in any direction at right angles to its major axis. There shall not be any cracking or breaking to the extent that:
a) The fifitting becomes unfifit for use; or
b) Live parts become exposed to unintentional contact.
The fifitting shall be conditioned in a circulating-air oven for 7 days at 90.0 ±1.0°C (194.0 ±8°F) and then cooled to room temperature before being subjected to the Crushing test. See also 11.8.1. The fifitting shall comply with the requirements of the dielectric voltage withstand test described in 11.4.
11.7.2 Any testing equipment that can apply a steady pressure of 334 N (75 lbf) to the fifitting may be employed. The fifitting shall be tested between two 13-mm (1/2-in) or thicker parallel flflat maple blocks. Care shall be taken so that the crushing force is not applied suddenly.
11.7.3 Bodies molded of solid polyvinyl chloride, TPE, or thermoset need not be tested.
这个334N压力测试没有见过,谁做过需要怎样的治具?谢谢!

46.5.1 One sample of the unit shall withstand for 1 minute a steady crushing force of 75 pounds-force (334 N) applied at right angles to the mounting surfaces. The enclosure is to be tested between two parallel, flat, hardwood blocks, each not less than 1/2 inch (12.7 mm) thick. One block is to contain slots into which the blades of the device are to be fully inserted. The crushing force is to be applied gradually in a direction normal to the mounting surface.- p2 c( C! g  ?- i
