請教各位高手,關(guān)于CSA插頭插座標(biāo)準(zhǔn)的

本人現(xiàn)在學(xué)習(xí)該標(biāo)準(zhǔn),遇到不少問題,還望各位大師不吝賜教.小弟謝過了!
1、Terminal plates through which binding head screws or machine screws are threaded.中的terminal plates是否指螺絲的墊圈?
2、multicontact device是指的哪種裝置?
3、To prevent incorrect mating of a 3-wire grounding type of attachment plug with a 2-wire device or a 3-wire device, two obstructions shall be provided on a nongrounding outlet device (1-15R) and a single obstruction shall be provided on a grounding outlet device 5-15R, 5-20R, 6-15R, and 6-20R.其中obstruction指的是什么?

請問那位有CSA C22.2 NO.158 有關(guān)terminal blocks的標(biāo)準(zhǔn),小弟在此急需要此標(biāo)準(zhǔn),很想了解其中Clause 6.11中的氨水腐蝕試驗.希望大俠們能多多指教.
