2、ies of the Department of Defense. 1. SCOPE 1.1 Scope. This specification covers the requirements for cleaning classifications and packaging (preservation, packing, and marking) of industrial gas (oxygen and nitrogen) production equipment, accessories, and associated support items (see 6.5 and 6.8).

The cleanliness classification shall be determined by the specific use application of the item. The cleanliness classifi- cation applies to the surfaces and passages that, whe
7、n in use, will be contacted by the industrial gas. Exterior surfaces of items which will not be exposed to the industrial gas shall be cleaned in accordance with procedure C-1 of MIL-P-116 after completion of all other required cleaning, drying, and plugging or capping of all item openings. Items of
8、 critically cleaned systems which will have their condition degraded during installation (welding, soldering, brazing, and so forth) shall be initially classified for class E cleanliness and shall be reclassified as applicable and cleaned with the complete system or subsystem after the installa- tio
9、n has been completed (for Navy, see MIL-STD-1330). If a cleanliness classifi- cation is not specified then class D cleanliness shall apply. (a) Class A cleanliness. Class A cleanliness is the class of cleanli- ness applied to items that employ moving parts that will in use contact liquid or gaseous
10、oxygen. Examples are: compressors, pumps, valves, flow meters, rotometers, and so forth. (b) Class B cleanliness. Class B cleanliness is the class of cleanli- ness applied to items that employ fixed surfaces that will in use contact liquid or gaseous oxygen. Examples are: fixed plumbing fixtures, su
11、ch as tubing, connectors, fittings, filters, rupture assemblies, and so forth. ness applied to pressure-measuring devices using a Bourdon tube or bellows-type movement. Examples are: pressure-monitoring devices and flow or liquid level differential pressure instruments. (d) Class D cleanliness. Clas
12、s D cleanliness is the class of cleanli- ness applied to items that will in use contact a c3mpressed air atmosphere or a pure product fluid. Examples are: plumbing fixtures, such as tubing, connectors, fittings, filters, and so forth, of pure product circuits, controls, tanks, and so forth. (e) Clas
13、s E cleanliness. Class E cleanliness is the class of cleanli- ness applied to items that will in use not contact liquid or gaseous oxygen, an oxygen-enriched atmosphere or pure product fluids. An example is the plumbing fixtures of the process air circuit of a gas generating plant. This classificati
14、on shall also be applied to items that are to be cleaned prior to installation in a system and then cleaned with the complete system or subsystem. (c) Class C cleanliness. Class C cleanliness is the class of cleanli- 2. APPLICABLE DOCUMENTS 2.1 Government documents. 2.1.1 Specifications, standards.
