ISO class 8 Cleanroom

Assembly, test and integration of spacecraft components, instruments and structures, Moments of Inertia (MOI) and centre of gravity of flight hardware.

The MSSL ISO class 8 cleanroom is newly commissioned facility that allows larger structures to be processed, assembled and tested at MSSL. 

placeholder

The cleanroom is divided into two areas namely the low bay and two storey high bay area. A loading bay area adjoins the high bay area. The loading bay is separated from the main cleanroom via roller shutter doors which are six meters high.

Cleanroom validation: Yes, by external independent contractors

Other services

The ISO class 6 cleanroom has a total of 7 liquid nitrogen outlet points mainly for use on the various vacuum test chambers and Optical calibration chamber. The liquid nitrogen supply lines are continous Super Insulated Vacuum Lines (SIVL) which minimises liquid nitrogen boil off. The SIVL supply lines are fitted with stay fulls to ensure that only liquid nitrogen is fed from the outlets no matter how many systems are demanding LN2.
