This paper proposes an integrated method for providing the thermal tests of spaceborne equipment. The method allows revealing of additional valid failure modes and provides more complete test results` analyses, than the point estimate. In order to implement the method the special instrument is created – the “Resource” installation. The effectiveness of the installation is confirmed by conduction of tests of three specimens of IKFS-2 instruments of a total duration over 8 thousand hours. The installation represents the conditions of sealed housing of Meteor-M spacecraft, including the heat transfer intensity, which provides the full modeling of real-life operating conditions.
