Environmental testing - Part 2-1: Tests - Test A: Cold

IEC 60068-2-1:2025 specifies temperature tests at low temperatures, generally referred to as "cold tests", that are applicable to non-heat-dissipating and heat-dissipating specimens, to determine the ability of components, equipment, or other articles to be used, transported or stored at low temperature.

This document is applicable to energized as well as non-energized specimens that normally achieve temperature stability during the test. The specimens can be subject to test in packed condition (to simulate transportation and storage) or in unpacked condition (to simulate use).

This document does not specify tests to determine the impact of temperature changes on specimens.

This seventh edition cancels and replaces the sixth edition published in 2007. This edition constitutes a technical revision.
