MIL-STD-1330D(SH)
20 September 1996
5.17.2 Objective quality evidence (OQE). Objective quality evidence testifying to the satisfactory accomplishment of the following inspections required by this standard shall be recorded and maintained for not less than 3 years.
(a) Cleanroom maintenance inspections required by 5.1.2. (b) Results of testing specified by 5.9.
(c) Results of inspections or analyses addressed in 5.13 when directed by this standard.
(d) Signature or initial of witnesses or inspectors when directed by
5.17.1.
5.17.3 Audit or surveillance. Facilities performing oxygen cleaning may be subject to audits or surveillance made by higher level organizations such as an assurance office representative, an authorized representative of NAVSEA, or the agency concerned for compliance with this standard in accordance with NAVSEA
TL855-AA-STD-010. Audit or surveillance results shall be recorded (see 6.3).
5.17.4 Accountability of small items. For most applications, measures to prevent entry of small items into openings is 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 sections contains information of 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 effects the safe operation of naval surface ship, submarine and diving oxygen systems, oxygen enriched systems, and interfacing systems. Absence of conformance 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 Issue of DoDISS. When this standard is used in acquisition, the applicable issue of the DoDISS must be cited in the solicitation (see 2.2.1 and
2.3).
6.3 NAVSEA approval and direction. 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.
6.4 Safety precautions. If an oxygen monitor with alarm is used as specified in 4.7.1, it should be in accordance with OPNAVINST 5100.19C.
