clamped at the same place. For each connection, the conductors are either pushed as far
as possible into the terminal or are inserted so that adequate connection is obvious.
将导线五次引入和脱开，每次使用新导线做试验，但第五次除外，这时将第四次引
入的导线夹紧在同样的位置。每次連接时应尽可能深地将导线压入端子或如此引入
导线使得足够的連接长度变得显而易見。
After each connection, the conductor is subjected to a pull of the value shown in table 8; the
pull is applied without jerks, for 1 min, in the direction of the longitudinal axis of the
conductor space.
每次引入导线后用表 8规定的拉力拉动导线。拉力应均匀施加在接线腔纵轴方向作

connected and disconnected only once.
然后采用 12.3.2规定最大截面和最小截面绞合硬铜导线重做试验；但这類导线仅引

Compliance is checked by the following test which is made on three specimens of
socket-outlets which have not been used for any other test.
检验︰做下述试验，试验时使用三个未做过其它试验的试样。
The test apparatus, the principle of which is shown in figure 12a, shall be so constructed
that
试验装置（其主要架构如图 12 a所示）的设计应保证
− a specified conductor properly inserted into a terminal is allowed to be deflected in any
of the 12 directions differing from each other by 30°, with a tolerance referred to each
direction of ±5°, and
一根引入端子的导线，可在相距 30°±5°的 12 个方向上弯曲；
− the starting point can be varied by 10° and 20° from the original point.
起始点可从原点推移 10°和 20°。
NOTE 1 A reference direction need not be specified.
注1︰不必规定基准方向。
The deflection of the conductor from its straight position to the testing positions shall be
effected by means of a suitable device, applying a specified force to the conductor at a
certain distance from the terminal.
必须借助一种合适的弯曲装置使导线从直线位置弯向试验位置，该装置对导线施加
规定的力使导线偏離规定的距離。
The deflecting device shall be so designed that
弯曲装置的架构应保证
− the force is applied in a direction perpendicular to the undeflected conductor;
弯曲力在垂直于尚未弯曲导线的方向上施加；
− the deflection is attained without rotation or displacement of the conductor within the
clamping unit;
弯曲导线时不会使导线在端子中转动或移动；
− the force remains applied while the prescribed voltage drop measurement is made.
在所述的电压降测量期间弯曲力继续作用。
Provisions shall be made so that the voltage drop across the clamping unit under test can
be measured when the conductor is connected, as shown for example in figure 12b.
必须预先采取措施使得可以测量接上导线的被试端子的电压降，例如采取图12b) 所
示的方法。
The specimen is mounted on the fixed part of the test apparatus in such a way that the
specified conductor inserted into the clamping unit under test can be freely deflected.
试样固定在试验装置的不动部件上的方法应使得选定的、被引入被试夹紧部件中的
导线可立即被弯曲。
NOTE 2 If necessary, the inserted conductor may be permanently bent around obstacles so that these do not
influence the results of the test.
注2︰必要的话，可使被试引入的导线永久地围绕一个障碍物弯曲而不使试验结果因此受到影响。
NOTE 3 In some cases, with the exception of the case of guidance for the conductor, it may be advisable to
remove those parts of the specimens which do not allow the deflection of the conductor corresponding to
the force to be applied.
注3︰在某些场合，除了导线的导向装置外最好将那些阻碍导线受力弯曲的试样部分拆除。

A clamping unit is fitted as for normal use with a rigid solid copper conductor having the
smallest nominal cross-sectional area specified in table 11 and is submitted to a first test
sequence; the same clamping unit is submitted to a second test sequence using the
conductor having the largest nominal cross-sectional area, unless the first test sequence
has failed.

第一輪试验；然后使同一夹紧部件接上最大截面的导线做第二輪试验，除非第一輪
试验没有通过。
The force for deflecting the conductor is specified in table 12, the distance of 100 mm being
measured from the extremity of the terminal, including the guidance, if any, for the
conductor, to the point of application of the force to the conductor.
弯曲力按表 12规定，其中 100mm距離从端子（包括可能有的导线用导向装置）的
端部至导线上力的作用点测量。
The test is made with continuous current (i.e. the current is not switched on and off during
the test); a suitable power supply should be used and an appropriate resistance should be
inserted in the circuit so that the current variations are kept within +5 % during the test.
试验应在电流連续流过的条件下进行（这意味着在试验期间不得切断和接通电流）︰
应使用合适的电源装置且必须在回路中接入一个合适的电阻使得电流波动控制在+5%。
A test current equal to the rated current of the socket-outlet is passed through the clamping
unit under test. A force according to table 12 is applied to the test conductor inserted in the
clamping unit under test in one of the 12 directions shown in figure 12a and the voltage
drop across this clamping unit is measured. The force is then removed.
使一个等于插座额定电流的试验电流流过被试夹紧部件。使一个按表 12的力作用在
引入被试夹紧装置的导线上使得导线按图 10 a) 所示的 12个方向之一弯曲，并测量
夹紧部件的电压降，然后撤去作用力。
The force is then applied successively on each one of the remaining 11 directions shown in
figure 12a, following the same test procedure.
然后依次在 10 a) 所示的其余 11 个方向上使用弯曲力并重做上述试验。
If, for any of the 12 test directions, the voltage drop is greater than 25 mV, the force is
maintained in this direction until the voltage drop is reduced to a value below 25 mV, but for
not more than 1 min. After the voltage drop has reached a value below 25 mV, the force is
maintained in the same direction for a further period of 30 s during which period the voltage
drop shall not have increased.
如果在 12 个弯曲方向中一个弯曲方向上电压降大于 25mV, 使弯曲力停留在该方向
上直至电压降回落到 25mV,以下，但停留时间不得超过 1 分钟。当电压降回落到
25mV 以下一个值时，弯曲力在同一方向上继续维持 30秒，在这段时间内电压降不
得上升。
The other two specimens of socket-outlets of the set are tested following the same test
procedure, but moving the 12 directions of the force so that they differ by approximately 10°
for each specimen.
试样组中其余兩个插座试样按同样方法做试验。试验时弯曲力弯曲的 12个方向在每
个试样上移动 10°。
If one specimen has failed at one of the directions of application of the test force, the tests
are repeated on another set of specimens, all of which shall comply with this new series of tests.
如果其中一个试样在其中一个试验力的弯曲方向上未透过试验，应再取一组试样重
做试验，该组试样必需透过所有重做的试验。
