This sta
25、ndard 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-A
26、G-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. 1.2 Applicability. This standard is applicable to all surface ships, submarines, and supporting shore base facilities which c
27、ontain any of the following: 1.2.1 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 divers life support air, air su
28、pplying oxygen generating equipment, emergency breathing air, emergency main ballast tank blow, electronics air, low pressure vital and non-vital air, and deballast air. 1.2.2 Compressed gaseous and liquid nitrogen systems and components supporting or interfacing with services containing 25% or less
29、 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, cont
30、aining greater than 25% by volume oxygen during normal operation, it will be cleaned as specified in MIL-STD-1330. 1.2.3 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 i
31、nterface is intended to maintain the cleanliness requirements specified herein. 1.2.4 Open ended applications, other than air supplying divers life support, will use best commercial practice to remove loose scale, dust, grit, filings, oil, and grease. Open ended applications supplying air for divers
32、 life support will be cleaned as specified herein. 2. APPLICABLE DOCUMENTS 2.1 General. The documents listed in this section are specified in sections 3, 4, or 5 of this standard. This section does not include documents cited in other sections of this standard or recommended for additional informati
