插头做好后,需做高压测试(Hi-pot test),IEC-60884标准中只规定一个2000V(1、所有极连一起与本体之间;2、每一极与本体的其它极之间),一般都会把这个2000V理解成内压,外压在标准里没有说明,而一般会根据实际情况,将外压定为4000V。请问以上的做法有没有什么不当的地方。

不是很清楚呢,
好像都对呢
4000V是不考虑接地的情况下进行的
而2000V是考虑接地下进行的。

外压怎么没有说明呢?60884的17.1.2里面明确描述了测试的位置

弄个中英文对照的:
17.1 The insulation resistance is measured with a d.c. voltage of approximately 500 V, the measurement
being made 1 min after application of the voltage.
用约500V 直流电压测量绝缘电阻,施加电压後1 分钟进行测量。
The insulation resistance shall be not less than 5 MΩ.
绝缘电阻不得超过5MΩ。
17.1.1 For socket-outlets, the insulation resistance is measured consecutively:
对於插座应依次在如下部位测量绝缘电阻︰
a) between all poles connected together and the body, the measurement being made with
a plug in engagement;
在所有連接在一起的极与本体之间,测量时插入插头;
b) between each pole in turn and all others, these being connected to the body with a plug
in engagement;
依次在每个极与所有其它极之间,测量时所有其它极要在插头处於插合的情况下
連接到本体上;
c) between any metal enclosure and metal foil in contact with the inner surface of its
insulating linings, if any;

terminal(s) or earthing contact(s), if any, of portable socket-outlets;

(若有)之间;
e) between any metal part of the cord anchorage of portable socket-outlets and a metal rod
of the maximum diameter of the flexible cable inserted in its place (see table 17).
在移动式插座的线夹内的每个金属部件与一根直径等於软线最大直径的、且插入
软线的接线位置的金属杆之间(見表17)。
The term "body" used in a) and b) includes all accessible metal parts, metal frames
supporting the base of flush-type socket-outlets, metal foil in contact with the outer surface
of accessible external parts of insulating material, fixing screws of bases or covers and
coverplates, external assembly screws, earthing terminals or earthing contacts.
上述a)和b)条中所述的“本体"包括可触及金属部件、支撑暗装插座底座的金属框
架、与可触及外部绝缘件的外表面接触的金属箔、底座或帽盖和盖板的紧固螺丝、
外部装配螺丝、接地端子或接地措施。
NOTE 2 Measurements c), d) and e) are not made on non-rewirable portable socket-outlets.
注2︰不可拆线移动式插座不进行上述c)、d)和e)的测量;
NOTE 3 While wrapping the metal foil round the outer surface or placing it in contact with the inner surface of parts
of insulating material, it is pressed against holes or grooves, without any appreciable force, by means of a
straight unjointed test finger test probe 11 of IEC 61032.
注3︰用金属箔包覆绝缘件的外表面或贴在绝缘件的内表面上时,应将金属箔轻轻压入孔洞或凹陷中,压入时使用
直线无关节的IEC 61032 探棒11 的试验指。
17.1.2 For plugs, the insulation resistance is measured consecutively
对於插头应依次在如下部位测量绝缘电阻︰
a) between all poles connected together and the body;
在所有連接在一起的极与本体之间;
b) between each pole in turn and all others, these being connected to the body;
依次在每个极与所有其它极之间,测量时所有其它极应連接到本体上;
c) between any metal part of the cord anchorage, including clamping screws, and earthing
terminal(s) or earthing contact(s), if any;
在线夹内的每个金属部件(包括夹紧螺丝)与接地端子或接地触点(若有)之间;
d) between any metal part of the cord anchorage and a metal rod of the maximum diameter
of the flexible cable inserted in its place (see table 17).
在线夹内的每个金属部件与一根直径等於软线最大直径的、且插入软线的接线位
置的金属杆之间(見表17)。
The term "body" used in a) and b) includes accessible metal parts, external assembly
screws, earthing terminals, earthing contacts and a metal foil in contact with the outer
surface of accessible external parts of insulating material, other than the engagement face.
上述a)和b)条中所述的“本体"包括可触及金属部件、外部装配螺丝、接地端子、
接地插销以及与可触及外部绝缘件的外表面(插合面除外)接触的金属箔。
NOTE 1 Measurements c) and d) are not made on non-rewirable plugs.
注1︰不可拆线插头不进行上述c) 和 d)的测量;
NOTE 2 While wrapping the metal foil round the outer surface or placing it in contact with the inner surface of parts
of insulating material, it is pressed against holes or grooves, without any appreciable force, by means of a
straight unjointed test finger test probe 11 of IEC 61032.
注2︰用金属箔包覆绝缘件的外表面或贴在绝缘件的内表面上时,应将金属箔轻轻压入孔洞或凹陷中,压入时使用
直线无关节的IEC 61032 探棒11 的试验指。
17.2 A voltage of substantially sine-wave form, having a frequency of 50 Hz or 60 Hz, is applied for 1 min
between the parts indicated in 17.1.
在17.1 条所述的部件之间施加一个频率为50Hz 或60Hz 近似正弦波形的试验电压1 分钟。
The test voltage shall be as follows:
试验电压大小如下︰
? 1250 V for accessories having a rated voltage up to and including 130 V;
对於额定电压130V 及以下的插接装置,1250V;
? 2000 V for accessories having a rated voltage exceeding 130 V.
对於额定电压130V 以上的插接装置,2000V。
Initially, not more than half the prescribed voltage is applied, then it is raised rapidly to the full value.
开始是施加不足规定值一半的电压,然後迅速升压直至完全达到规定值。
No flashover or breakdown shall occur during the test.
试验期间不得出现闪络或击穿。
NOTE 1 The high-voltage transformer used for the test should be so designed that, when the output terminals are
short-circuited after the output voltage has been adjusted to the appropriate test voltage, the output current is at
least 200 mA.
注1︰试验时使用的高压变压器必须具有这样的特性︰将输出电压调至相应的试验电压後使输出端子短路,这时输出电流应
至少为200mA。
NOTE 2 The overcurrent relay should not trip when the output current is less than 100 mA.
注2︰输出电流小於100mA 时过电流继电器不得动作。
NOTE 3 Care is taken that the r.m.s. value of the test voltage applied is measured within ±3 %.
注3︰注意测量施加的电压的均方根值时精确到±3%。
NOTE 4 Glow discharges without drop in the voltage are neglected.
注4︰无电压降的辉光放电忽略不计。

版主提供的双语标准很详尽。可否这样理解:
a) between all poles connected together and the body;
在所有連接在一起的极与本体之间;
这条规定的是外压;
b) between each pole in turn and all others, these being connected to the body;
依次在每个极与所有其它极之间,测量时所有其它极应連接到本体上;
这条规定的是内压;

而标准中只是提到了以额定电压130V为界限的2000V和1250V,如果上面内外压的理解正确的话,似乎内外压的值都是一样的,要么都是1250V,要么都是2000V。这样对吗?

不过VDE审厂员告诉我们将外压设定在家2200-2500V,后面其他国家审厂员来我司审厂都没投述此问题,因为此前我司将外压调试到达4000-4500V,VDE审厂员说这样是破坏性测试,而不合格。
