* (According to standard DIN 28 428, the base pressure is that
measured in a leak-free test dome, 48 hours after the comple-
tion of test dome bake-out, with a Turbopump fitted with a Con-
Flat flange and using the recommended pre-vacuum pump)
When the Turbo-V 81-M has been stored at a tem-
perature less than 5°C, wait until the system has
reached the above mentioned temperature.
