scope:

This standard provides the requirements for cleaning of compressed air systems and components. Each activity should implement the applicable requirements of this document through a locally prepared and approved procedure. Activities subject to additional quality assurance requirements such as NAVSEA SS800-AG-MAN-010/P-9290 or NAVSEA SS521-AA-MAN-010 will obtain procedure approval from the applicable certifying activity. This standard does not apply to reactor plant air systems.

Applicability.

This standard is applicable to all surface ships, submarines, and supporting shore base facilities which contain any of the following:

Compressed air systems and components. The cleanliness boundary includes all material designed for and normally wetted by low, medium, or high pressure air as specified in NAVSEA S9086-SY-STM-010/CH-551. Specific systems included are diver's life support air, air supplying oxygen generating equipment, emergency breathing air, emergency main ballast tank blow, electronics air, low pressure vital and non-vital air, and deballast air.

Compressed gaseous and liquid nitrogen systems and components supporting or interfacing with services containing 25% or less oxygen. The cleanliness boundary includes all material designed for and normally wetted by compressed gaseous or liquid nitrogen. For all cases, if the system or component interfaces with an oxygen or oxygen-enriched system or component, including gaseous or liquid oxygen generating equipment, containing greater than 25% by volume oxygen during normal operation, it will be cleaned as specified in MIL-STD-1330.

Equipment which comes in contact with or is used to transfer any fluid from its source to a system or component within any of the boundaries defined in 1.2.1 and 1.2.2 when such interface is intended to maintain the cleanliness requirements specified herein.

Open ended applications, other than air supplying diver's life support, will use best commercial practice to remove loose scale, dust, grit, filings, oil, and grease. Open ended applications supplying air for diver's life support will be cleaned as specified herein.
