Iec60068 2 14

IEC 60068-2-14 is an international standard that outlines the procedure for conducting change of temperature tests on specimens. The test aims to assess the effects of temperature changes rather than the effects of extreme temperatures alone. It specifies parameters such as conditioning temperatures, times, rate of change, cycles, and heat transfer for accurate testing.

INTRODUCTION

A change of temperature test is intended to determine the effect on the specimen of a change
of temperature or a succession of changes of temperature.

It is not intended to show effects which are due only to high or low temperatures. For these
effects, the dry heat test or the cold test should be used.

The effect of such tests is determined by

values of high and low conditioning temperature between which the change is to be
effected,
- the conditioning times for which the test specimen is kept at these temperatures,
- the rate of change between these temperatures,
- the number of cycles of conditioning,
- the amount of heat transfer into or from the specimen.

Guidance on the choice of suitable test parameters for inclusion in the detail specification is
given throughout this standard.
