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.

w/ Change 1

5.14.2 Course of instruction.

5.14.2.1 Certified Oxygen Clean Instructor. Personnel qualified as Certified Oxygen Clean Instructors shall successfully complete an oxygen clean instructor course. The location and content of the course shall be as authorized by NAVSEA. The course content shall include all requirements, directions, and provisions of this standard. Requalification of Certified Oxygen Clean Instructors shall be as specified in 5.14.3. Personnel qualified as Certified Oxygen Clean Instructors and whose job function provides continuous proficiency in the requirements of this standard should be designated Senior Certified Oxygen Clean Instructors by the local command or activity. Examples of job functions that provide continuous proficiency include cleanroom supervisors and personnel teaching oxygen clean instructor courses.

5.14.2.2 Certified Oxygen Clean Worker. Personnel qualified as Certified Oxygen Clean Workers shall successfully complete an oxygen clean worker course taught by a Certified Oxygen Clean Instructor. The location and content of the course shall be authorized by the local command or activity. The course content shall, at a minimum, include those requirements of this standard that pertain to the safe accomplishment of work performed at the local command or activity. Requalification of Certified Oxygen Clean Workers shall be as specified in 5.14.3.

5.14.3 Requalification. Personnel shall requalify every 3 years by completing an accelerated course of instruction that reviews at a minimum the requirements for oxygen and cleaning agent safety, maintenance of oxygen cleanliness, loss of oxygen cleanliness, packaging, certification, and any changes or revisions to this standard. The local command or activity may exempt Senior Certified Oxygen Clean Instructors from requalification. Requalification of Certified Oxygen Instructors shall be performed by a Senior Certified Oxygen Clean Instructor. Requalification of Certified Oxygen Clean Workers shall be performed by a Certified Oxygen Clean Instructor, or by completing a NAVSEA approved electronic-learning Oxygen Clean Worker Requalification Course.

5.15 Validation of the component cleaning process.

5.15.1 Periodicity. Validation of the aqueous component cleaning process shall be performed annually as specified in 5.15.2. This validates the entire process including the pre-clean, final clean, rinse, and dry steps. Each operator should perform the validation within a 3-year period. Records of the results of the validations shall be maintained for not less than 3 years. Failure to meet the validation requirements shall be immediately corrected, assessed for impact on previously delivered oxygen clean material, and recorded (see 6.3).

5.15.2 Procedure. Three monel or cres 304 or 316 coupons of dimensions 0.875 to 1.125 inches wide by 3.875 to 4.125 inches high by 0.0625 to 0.125 inches thick shall be cleaned as specified in 5.2. Each coupon shall be weighed on a scale capable of measuring 0.1 mg. All three coupons shall be contaminated with 75 to 100 mg of the same soil and weighed. The soils used shall be MIL-PRF-24139 hydrocarbon grease, SAE-AS8660 silicone grease, and MIL-PRF-27617 fluorinated grease, or equal. The contaminated coupons shall be cleaned as specified in 5.2. After cleaning, the final weight of each coupon shall indicate that not less than 99.9 percent of the soil was removed.

5.16 Packaging, identification, and storage.

5.16.1 Packaging.

5.16.1.1 Applicability. Certified oxygen clean components cleaned internally and externally shall be packaged as specified in 5.16.1.2. Certified oxygen clean items cleaned internally only, such as hoses or piping assemblies, shall be packaged as specified in 5.16.1.3.

5.16.1.2 Internally and externally cleaned components. Using film as specified in Table XI, packaging shall be accomplished as follows:

a. Sealing of openings. Items with openings leading to cleaned inner surfaces, should be sealed as specified in

5.16.1.3.

b. Intimate cushioning. Heavy items or items having threads, sharp points, or edges which could damage the barrier packaging shall be cushioned with film. Secure the cushioning film with tape whose adhesive shall not come in contact with the cleaned component.
