TS 2934

TS 2934 is a standard focused on the choice of colours used for marking resistors and capacitors in electronic equipment. Read together with its title and scope, it addresses the nominal values of the centre colours used in coding and identification, providing a common reference for which colours are to be selected for the marking system.

In general technical practice, colour coding is a compact visual language for components that are too small for conventional printed labelling. For resistors, colour bands are commonly used to convey value and related identification information, while capacitors may also rely on visible marking schemes for differentiation. The practical purpose is consistent recognition during manufacture, inventory handling, assembly, and maintenance.

The document’s covered subject is therefore the colour selection basis for these two major passive component families used in electronic devices. As broader technical context, effective colour coding depends on factors such as legibility, durability of the marking, and reliable visual distinction, but these are general considerations about the subject area rather than specific claims about requirements stated in the standard itself.

More broadly, the standard sits at the intersection of colour-code terminology and electronic component identification, helping establish a shared visual language for resistors and capacitors. Its withdrawn status makes it mainly relevant as a historical reference for the practice of the period, while the description here remains confined to the subject matter indicated by the title and scope.
