EN 55014-1:2006+A1+A2标注解读 4

If the original lead of the appliance is shorter than the necessary length it shall be extended or replaced by a similar lead.
如果器具原来的引线短于所需的长度，应延长或用类似质量的电源引线代替。

Any plug or socket which will not pass through the absorbing clamp due to its size shall be removed or, especially in the case of controversy with regard to the banning of sales or withdrawal of a type approval the lead may be replaced by a lead of similar quality with the necessary length.

应拆去任何由于尺寸原因不能通过吸收钳的插头或插座，或者特别是在事关禁止销售或取消形式认可的争论时，引线应由所需长度的类似质量的引线代替。

NOTE λ max is the wavelength corresponding to the lowest frequency at which measurements are to be made for instance 10 m at 30 MHz.

λ max对应所要测量的最低频率点的波长，例如在30MHz时为10m。

6.2.4 If the r.f. isolation between mains supply and the input of the absorbing clamp on the side of the appliance appears to be insufficient, a fixed ferrite clamp (see CISPR 16-1-3) should be placed along the lead at a distance of about 6 m from the appliance. This improves the stability of the loading impedance and reduces extraneous noise coming from the mains supply. For more information see Clause 4 of CISPR 16-1-3.

如果在电源与在器具一侧的吸收钳之间的射频隔离不足，应在离器具6m处沿线放置一个固定的铁氧体吸收钳（见CISPR 16-1-3）。这样可以提高负载阻抗稳定性和减少来自电源的外部噪声。详见CISPR 16-1-3的第4章。

6.3 Special requirements for appliances having auxiliary apparatus connected at the end of a lead other than the mains lead

在非电源引线端连接有辅助装置的器具的特殊要求

6.3.1 Measuring arrangement
6.3.1.1 Auxiliary leads normally extendible by the user, for instance with a loose end or leads fitted with a (by the user) easily replaceable plug or socket on one or both ends, shall in accordance with 6.2.3 be extended to a length of about 6 m. Any plug or socket which will not pass through the absorbing clamp due to its size shall be removed (see 6.2.3).

辅助引线通常可由使用者延长是，例如带一个自由端，或者在一端或两端装有（由使用者）容易替换的插头或插座的引线，应按6.2.3延长至大约6m的长度。应拆去任何由于尺寸原因不能通过吸收钳的插头或插座（见6.2.3）。

6.3.1.2 If the auxiliary lead is permanently fixed to the appliance and to the auxiliary apparatus and:

如果辅助引线是长久地固定到器具和辅助装置的，

– is shorter than 0,25 m, measurement are not to be made on these leads;

短于0.25m的，不在该引线上测量。

– is longer than 0,25 m but shorter than twice the length of the absorbing clamp, it shall be extended to twice the length of the absorbing clamp;

长于0.25m但是短于测量吸收钳长度两倍的，应延长到吸收钳长度的两倍。

– is longer than twice the length of the absorbing clamp, measurements shall be made using the original lead.
长于吸收钳长度两倍的，使用原引线进行测量。

When the auxiliary apparatus is not necessary for the operation of the main appliance (e.g. a power nozzle to a vacuum cleaner) and a separate test procedure for the auxiliary apparatus is specified elsewhere in this standard, only the lead, but not the auxiliary
apparatus, shall be connected. (However, all measurements on the main appliance in accordance with 6.3.2 are to be made.)

当辅助装置不是主体器具运行所必须的（如真空吸尘器的动力吸嘴）以及本部分的其他地方规定有辅助装置的单独试验程序是，应只接引线而不解辅助装置。（然而，按6.3.2在器具主体上所有的测试都应进行）。

用功率吸收钳测试辐射骚扰时，测试过程中功率吸收钳在线缆上移动不？还是把功率吸收钳放在一个固定的位置。

    你这个0.6m指的是什么？
