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.This edition includes the following significant technical changes with respect to the previous edition:a) revision of the introduction and scope;b) inclusion of new figures and symbols for clarification purposes;c) clarification of the test procedure for ascertaining high or low air velocity in the test chamber;d) clarification of the requirements for measuring points around, on or in specimens;e) reintroduction of the nomogram procedure for the correction of the conditioning temperature when testing with high air velocity (Test Ad and Test Ae);f) revision of the temperature tolerances of the test;g) revision of standardized requirements for the relevant specification and test report;h) inclusion of the advantages and disadvantages of the testing procedures.

Environmental testing - Part 2-1: Tests - Test A: Cold
IEC 60068-2-1:2007 Deals with cold tests applicable to both non heat-dissipating and heat-dissipating specimens. For non heat-dissipating specimens, Tests Ab and Ad do not deviate essentially from earlier issues. Test Ae has been added primarily for testing equipment that requires being operational throughout the test, including the conditioning periods. The object of the cold test is limited to the determination of the ability of components, equipment or other articles to be used, transported or stored at low temperature. Cold tests cover by this standard do not enable the ability of specimens to withstand or operate during the temperature variations to be assessed. In this case, it would be necessary to use IEC 60068-2-14. The cold tests are subdivided as follows: - Cold tests for non heat-dissipating specimens: * with gradual change of temperature, Ab; - Cold test for heat-dissipating specimens: * with gradual change of temperature, Ad, * with gradual change of temperature, specimen powered throughout, Ae. The procedures given in this standard are normally intended for specimens that achieve temperature stability during the performance of the test procedure. Temperature chamber(s) are constructed and verified in accordance with specifications IEC 60068-3-5 and IEC 60068-3-7. Further guidance for dry heat and cold tests can be found in IEC 60068-3-1 and general guidance in IEC 60068-1. This sixth edition deals with cold tests applicable both to non heat-dissipating and heat-dissipating specimens. For non heat-dissipating specimens, Tests Ab and Ad do not deviate essentially from earlier issues. Test Ae has been added primary for testing equipment that requires being operational throughout the test including the conditioning periods.
