The code specified in Clause 2 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 Publication 60063, Preferred Number Series of Resistors and Capacitors. The code specified in Clause 3 gives a system for marking resistance and capacitance values by means of letters and digits. The code specified in Clause 4 gives a system for marking the tolerance on resistance and capacitance values by means of a letter. The code specified in Clause 5 gives systems for marking of date codes on capacitors and resistors by means of letters and digits. The code (index) specified in Clause 6 gives a coding system for the dielectric material. 2 Colour code for fixed resistors 2.1 The colour code for indicating resistance values to two and three significant figures, tolerances and if needed, the indication of the temperature coefficient of fixed resistors shall be as given in Sub-clauses 2.2, 2.3 and 2.4. 2.2 The first band shall be the one nearest to the end of the resistor and the bands shall be so placed and spaced that there can be no confusion in reading the coding. 2.3 Any additional coding shall be so applied as not to confuse the coding for value and tolerance. 2.4 Table I Values corresponding to colours For the indication of temperature coefficients according to the code as described above one of the following methods shall be used: a) a colour band as the sixth and wider band; b) an interrupted colour band as the sixth band; c) a helix. For cylindrical types the helix shall be superimposed on the full length of the existing bands of colour code indicating the resistance value and tolerance, with the helix covering not less than 270 degrees of the circumference.

Colour code marking of the temperature coefficient shall only be used in combination with three significant figures. 2.4.1 Example of colour code marking for resistance values with two significant figures Resistor of 27 000 ? with a tolerance of ±5 %. 2.4.2 Example of colour code marking for resistance values with three significant figures Resistor of 249 000 ? with a tolerance of ?1 %. NOTEIn order to avoid any confusion, the last band shall be 1,5 to 2 times wider than the other bands. 2.4.3 Example of colour code marking for resistance values with three significant figures and temperature coefficient Resistor of 249 000 ? with a tolerance of ?1 % and a temperature coefficient of ?50 ? 106 ?C.
