This International Standard specifies marking codes for resistors and capacitors and indexes for the dielectric material and the electrodes of plastic film and paper capacitors. The code specified in Clause 3 gives a colour coding for fixed resistors. It is intended for use with the values of the E6 to E192 series as specified in IEC 60063. The code specified in Clause 4 gives a system for marking resistance and capacitance values by means of letters and digits. The code specified in Clause 5 gives a system for marking the tolerance on resistance and capacitance values by means of a letter. The code specified in Clause 6 gives systems for marking the date codes on capacitors and resistors by means of letters and digits. The code (index) specified in Clause 7 gives a coding system for the dielectric material.
