在ANSI-NEMW WD 6-2012标准里许多尺寸有个TYPE是什么意思，[img=0,1]file:///C:\Users\Administrator\AppData\Roaming\Tencent\Users\2251437659\QQ\WinTemp\RichOle\~~W0[T6DMG4A68{W)E07U)J.png[/img]有的地方有尺寸公差有这标记，有的地方没有公差也有这标记，请问下这TYP是什么意思，在插头的插脚处标注TYP，我想了解下这是注明它的公差还是什么意思？美式插片的厚度尺寸公差是多少？

是的。UL标准比较乱，理解起来难。

这个标准里有

* v; ~  M/ t6 u8 p; r6 C6 F非常感谢你提供的资料，确实这里的尺寸比WD 6里面更全些。美国标准里确实太多了，同一个东西尺寸都有几个地方有，测试方法也是的，什么UL 817、UL498。新手确实弄得很糊涂，一个没有公差的标准都不知道哪个最是标准要求的。

你仔细对比一下，这是两个不同的东西。他的测试项目都是根据标准来的，测试项目一般不会错，要错可能都是标准用错，所以看看产品到底是适用于哪个标准。

91 Retention of Plugs Tests
91.1 The contacts of a 1-15R, 5-15R, 5-20R, 6-15R or 6-20R configuration cord connector shall retain an
# d8 p, s0 f. E0 dattachment plug so that a force greater than 3 lbf (13 N) is required to withdraw the plug when tested as

91.3 Each of six devices is to be subjected to ten conditioning cycles of insertion and withdrawal of a
standard solid-blade attachment plug that has American National Standard detent holes in accordance
with Wiring Devices – Dimensional Specifications, ANSI/NEMA WD6, in rigidly mounted blades, following
which the plug is to be fully reinserted into the device. The mating plugs are to have the configuration

cord connector and tending to withdraw the plug from the device is then to be applied to the plug for 1
minute. The displacement of the plug shall not be greater than 0.079 inch (2 mm).

109 Retention of Blades Test
109.1 A flush or self-contained receptacle having a 5-15R, 5-20R, 6-15R, or 6-20R configuration shall be
subjected to the retention of blades test described in this Section.

The force applied to insert the gauge for any of the conditioning cycles is not to exceed 40 lbf (178 N).
The gauge is to have the dimensions indicated in Figure 109.1 but is not to have holes in the outer ends
of the blades.
109.5 Each of the line contacts of the receptacles is to be tested using the test blade illustrated in Figure
109.2. Each line contact shall be capable of withstanding for 1 minute a static 0.5 lbf (2.2 N) applied to
the test blade in a direction normal to the plane of the face of the specimen and in a direction that tends
to remove the test blade, when the test blade is fully inserted in the contact opening. There shall not be
more than 0.079 inch (2 mm) displacement of the test blade.
