IEC 60062:2004规定了电阻器和电容器的标记代码以及塑料薄膜和纸电容器的介电材料和电极的索引。与上一版相比，此版本包括以下重大技术变更: a)完成现有的代码系统 -具有三字符代码系统和四字符代码系统的电阻器； -具有字母代码系统的电阻温度系数； -电容器和电阻器的数据代码系统，具有10年周期代码（两个字符代码）、20年周期代码（四位数代码）、10年周期代码（四位数代码）和一个字符代码-四年周期。 b)用于塑料薄膜和纸电容器的介电材料的代码字母系统的扩展。

IEC 60062:2004 specifies marking codes for resistors and capacitors and indexes for the dielectric material and the electrodes of plastic film and paper capacitors. This edition includes the following significant technical changes with respect to the previous edition:
a) completion of the existing code systems for
- resistors with a three-character code system and a four-character code system;
- temperature coefficient of resistance with a letter code system;
- data code system for capacitors and resistors with the 10-year cycle code (two-character code), the 20-year cycle code (four-digit code), the 10-year cycle code (four-digit code), and a one-character code - four-year cycle.
b) extension with a code letter system for the dielectric material of plastic film and paper capacitors.
