Environmental testing - Tests. Tests and guidance: Combined temperature or temperature and humidity with low air pressure testsWhat is BS EN 60068 2 39 Temperature and humidity with low air pressure tests about? BS EN 60068 is a European standard that discusses environmental testing. BS EN 60068 2 39 is one of the parts of in the BS EN 60068 series that provides a description of test methods and guidance for testing of equipment or components under combined temperature or temperature and humidity with low air pressure tests. The object of combined testing is to investigate to
