A multi-purpose thermal insulation test apparatus is used for testing insulation materials, or other components. The test apparatus is a fluid boil-off calorimeter system for calibrated measurement of the apparent thermal conductivity (k-value) of a specimen material at a fixed vacuum level. The apparatus includes an inner vessel for receiving a fluid with a normal boiling point below ambient temperature, such as liquid nitrogen, enclosed within a vacuum chamber. A cold mass assembly, including the inner vessel and thermal guards, is suspended from the t...


1. A thermal insulation apparatus adaptable for use with a boil-off flow measuring device for determining the thermal performance of a testing material, comprising:a) an inner vessel extending within the testing material, said inner vessel having a top, a bottom, a sidewall and a first liquid port for receiving a cryogenic fluid having a normal boiling point below ambient temperature; b) an outer vacuum chamber enclosing said inner vessel and the testing material and having a second liquid port; c) a conduit passing through said second liquid port of sai...
