MIL-STD-1330-SUP-2 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.

MIL-STD-1330D(SH) APPENDIX B

20 September 1996

B.10.2.1 Subtract the initial weight of the filter (step B.9.2) from the final weight of the filter (step B.9.13) after filtering used NOC. Record the weight difference in mg. Multiply the weight difference by five, and record as post-cleaning (after use) mg/L total NVR in NOC.

B.10.2.2 Subtract the baseline (before use) NVR (from step B.10.1) from the post-cleaning (after use) total NVR (from step B.10.2.1). Record the difference as post-cleaning (after use) mg/L above baseline NVR in NOC.

B.10.2.3 Convert mg/L to ppm by dividing mg/L (from step B.10.2.2) by 1.075 (the average density of NOC in use) and record as ppm above baseline NVR in NOC.
