The White Sands Test Facility (WSTF) maintains several clean rooms and large areas that can be used for test article assembly and checkout. These areas range from Class 100 clean rooms and flow benches to large size assembly areas. These facilities were used for processing Shuttle and ISS hardware and continue to be used for processing the next generation of space flight and ground component hardware.
Equipment/
Capabilities
Class 100
-
A 20 x 24 x 8 ft clean room with a 6 x 12 ft anteroom is used for processing flight hardware. It is electrostatic discharge (ESD) rated, can reach vacuum down to 10 torr, is equipped with 3,000-psi nitrogen, helium, and has a workstation with a fume extraction system.
-
Precision cleaned hardware is processed in a 26 x 24 x 8 ft clean room.
-
Components are reassembled and function tested in a 14 x 21 x 8 ft clean room.
-
WSTF uses several Class 100 flow benches, each equipped with varying levels of facility supply including nitrogen, helium, oxygen, and compressed air.

Equipment/
Capabilities
Class 10,000
-
A 20 x 20 x 15 ft assembly room is equipped with facility 3,000-psi nitrogen and helium with the ability to supply up to 9,000 psi.
-
A 19 x 31 x 8 ft component clean room has facility 3,000-psi nitrogen, helium, and deionized water.
-
The Component Test Facility has several different soft-walled Class 10,000 work areas currently configured for decontaminatin thrusters.
-
All clean room garments are processed in a soft-walled Class 10,000 work area.
-
A portable 15 x 15 ft soft-walled Class 10,000 work environment wherever it is needed.
-
Building 416 is an environmentally controlled 60 by 40 x 22 ft facility with moveable 16 x 16 by 10 ft Class 100,000 (originally Class 10,000 when it was first built) soft-walled clean room located within the assembly room. The building is equipped with 6,000-psi helium, 750-psi nitrogen, fire suppression, and emergency eyewash and shower stations. The assembly room is explosion proof, and the floor is dropped approximately 3 in. for spill containment. The assembly room also has a 4,000-Ib Bridge Crane. Temperature can be controlled between 65- and 100-degrees Fahrenheit. Relative humidity is controlled between 30 and 50 percent.
-
OMS Tank Processing Area is a 20 by 24 by 12 ft (min. height) Class 10,000 clean room with facility 3000-psi nitrogen and 2,200-psi breathing air supply. The room is explosion proof (Class I Div. II Group B). There is an adjoining 24 by 10 by 10 ft Class 10,000 clean room with double door access between the two rooms.
-
Visually Clean and/or Large Test Article Assembly Areas
-
The South High Bay (SHB) is a 120 by 50 ft building standing 48 ft high. It contains 50 by 23 ft access doors on each end and a 15-ton bridge crane ruing along the length of the building.
-
A fully enclosed cleaning high bay, with a 15-ton bridge crane, is attached to the Component Services Section for working with large articles such as pressure vessels, tankers, and chambers; effluent retention and disposal is available.
