标准范围

IEC 60062:2016规定了电容器和电阻器的名称和标记代码。它提供了电阻或电容值及其容差的编码方法，包括电阻的颜色编码。它还提供适用于小部件标记的日期代码系统。与上一版相比，此版本包括以下重大技术变更:-引入用于对乘法器10-3进行编码的新代码颜色粉红色；-引入新的子条款，3.2编码颜色的规定，3.3抗性值和耐受性的标记方法，3.4 TCR标记方法，为了提高清晰度，颜色分配、R值和耐受性的编码以及TCR的编码的主题在单独的条款中处理；-包括通过中断色带进行TCR标记的图示；-包括关于固定长度代码标记的新子条款，电阻值的固定长度代码标记具有最多3个有效数字，因此固定代码长度为4个数字，电容值的固定长度代码标记具有最多2个有效数字，因此固定代码长度为3个数字；-引入两个新条款，第6条，电容器特有性质的编码和第7条，电阻器特有性质的编码；-引入附件A，电阻值的特殊三字符编码，带有三个有效数字。

IEC 60062:2016 specifies designation and marking codes for capacitors and resistors. It provides coding methods for the resistance or capacitance value and its tolerance, including colour coding for resistors. It also provides date code systems suitable for the marking of small components. This edition includes the following significant technical changes with respect to the previous edition:
- introduction of the new code colour pink for the coding of the multiplier 10^-3;
- introduction of new subclauses, 3.2 Prescription of code colours, 3.3 Methods for marking resistance value and tolerance, 3.4 Methods for TCR marking, for improved clarity, the subjects of colour assignment, coding of R value and tolerance, and coding of TCR is dealt with in separate clauses;
- inclusion of illustrations for TCR marking by interrupted colour band;
- inclusion of a new subclause on a fixed length code marking, fixed length code marking of resistance values with up to 3 significant digits, hence a fixed code length of 4 digits, and fixed length code marking of capacitance values with up to 2 significant digits, hence a fixed code length of 3 digits;
- introduction of two new clauses, Clause 6, Coding of properties specific to capacitors and Clause 7, Coding of properties specific to resistors;
- introduction of Annex A, Special three character coding of resistance value with three significant numerals.
