Figure 1 - Test cycle

Applies to equipment installed in partially weather-protected locations in a climate belonging to the group of 'moderate' climates covered by IEC 60721-2-1. Contains preferred test conditions as referred to in 8.4 of IEC 60605-1. The test cycle provided here is not intended to replace tests for other purposes, such as qualification, functional performance, environmental tests and tests aiming at the verification of the ability to survive or function during extreme conditions of storage, transportation or use.
