MIL-STD-1330 Precision Cleaning And Testing Of Shipboard Oxygen, Helium, Helium-Oxygen, Nitrogen, And Hydrogen SystemsThis standard provides the requirements for precision cleaning and testing of oxygen or oxygen-enriched systems and components; oxygen generating plants including nitrogen, hydrogen, and demineralized water support systems and components; and helium, helium-oxygen, and hydrogen life support systems and components. Each activity will 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.

5.17.4  Accountability of small items.  For most applications, measures to prevent entry of small items into openings are adequate; however, for applications such as oxygen-nitrogen plants, accountability of small items is also necessary.  To prevent entry of small items into systems or components, attach the item to the user or to a fixed piece of equipment by a wire, lanyard, or equivalent method.  When accountability is needed, a formal written record shall be maintained for tools, equipment, and temporary plugs or seals which are small enough to fit inside openings in systems or components and which are used in fabrication and assembly operations, unless internal surfaces can be visually observed and are certified to be satisfactorily clean prior to closure of the system or component involved.  A physical boundary shall be established to implement accountability when accountability is required.  Care shall be taken when establishing the physical boundary so that it precludes the inadvertent introduction of foreign materials and tools.  Extraneous tools, equipment, and material shall be removed from the proximity of an opening in a system or component.

6.  NOTES

(This section contains information of a general or explanatory nature that may be helpful, but is not mandatory.)

6.1  Intended use.  This standard practice is for the precision cleaning and testing of naval surface ship, submarine and diving oxygen, oxygen enriched systems, and interfacing systems.  The precision cleaning process specified herein is based on the processes and data reported in COMNAVSEA ltr's Ser 03Y2A/081 dtd 24 Mar 94, Ser 03Y2A/122 dtd 7 Apr 95, and Ser 03Y2A/275 dtd 11 Sept 95, and supplements thereof; and NASA Doc. No. WSTF-IR-95-0048 dated 30 Jan 95, and supplements thereof.  The performance of the precision cleaning process specified herein directly affects the safe operation of naval surface ship, submarine and diving oxygen systems, oxygen enriched systems, and interfacing systems.  Nonconformance can result in the introduction or failure to remove toxic and flammable contaminants that can cause catastrophic equipment failure and personnel injury and death.

6.2  Acquisition requirements.  Acquisition documents should specify the following:

a.    Title, number, and date of the standard.

b.    Identification of critical application systems or components as defined in 3.11, if applicable.

6.3  NAVSEA approval and direction.

6.3.1  Deviations from specified materials, procedures, and requirements and selection of specific alternative materials and procedures require NAVSEA approval or direction.  Requests should include supporting documentation.
