IPXXD 定义：电击防护等级
n respect of protection against electric shock, reference is made in the IEE Wiring Regulations to IPXXB and IPXXD as alternatives to IP2X and IP4X respectively.
防止80mm长度，直径12mm的测试手指接触。
D If a probe 100mm long and 1mm in diameter can enter the enclosure there will be adequate clearance from live parts防止100mm。
长度，直径1mm 测试手指接触。
扩展资料：
电击在国标中的定义如下：
在国标GB4776-84中1.4中触电中有：电击电流通过人体或动物体而引起的病理、生理效应。
在建筑物的电气装置 电击防护GB 14821.1-93中3-1也有定义。电击（触电）：电流通过人体或牲畜体而引起的病理生理效应。
在电击防护 装置和设备的通用部分GBT17045-1997中4.6也有定义。电击：电流 流 经 人体或动物体，使其产生病理生理效应。(IEV 826-03-04)

IPXXD测试方法：
Test for IPXXD
A probe is required. The probe consists of an insulated handle about 100 mm long and about 10 mm in diameter which ends in an insulated sphere (stop face) of 35 ± 0.2 mm diameter. On the opposite side of the sphere is a metal rod 100 mm long and 1
+0.05-0 mm in diameter. The live parts in the enclosure are connected together with wire and connected in series with a lamp, a suitable ELV supply and the 1mm diameter metal rod of the probe.
The tip of the metal rod is pressed gently against the opening. If the rod goes in there must be adequate clearance between the rod and the live parts i.e. the lamp should not light up. Tests must be made with the rod in all possible positions. The lamp must not light up.
The full diameter of the insulated sphere (stop face) must not be able to pass through the opening.
