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.

ANALYSIS OF RESIDUE IN SOLVENT BY OPTICALLY STIMULATED ELECTRON EMISSION USING A SURFACE QUALITY MONITOR

D.1 SCOPE

D.1.1 Scope. This appendix is a mandatory part of the standard. The information contained herein is intended for compliance. This appendix provides a procedure for determination of oil and grease in NAVSEA approved halogenated solvent by optically stimulated electronic emission (OSEE).

D.2 APPLICABLE DOCUMENTS

D.2.1 General. The documents listed in this section are specified in Appendix D of this standard. This section does not include documents cited in other sections of this standard or recommended for additional information or as examples. While every effort has been made to ensure the completeness of this list, document users are cautioned that they must meet all specified requirements of documents cited in Appendix D of this standard, whether or not they are listed.

D.2.2 Government documents.

D.2.2.1 Specifications, standards, and handbooks. The following specifications, standards, and handbooks form a part of this document to the extent specified herein. Unless otherwise specified, the issues of these documents are those cited in the solicitation or contract.

D.3 PROCEDURE

D.3.1 Summary of test method. The concentration of non-volatile organic residue in solvent is determined to be less than, equal to, or greater than the established acceptance criteria by serially evaporating 0.5 mL of solvent in a specially machined dish and measuring the OSEE of the dish using a Surface Quality Monitor (SQM). The amount of solvent evaporated is determined by whether or not the baseline is applied. If the baseline is not applied, acceptance criteria of 5 ppm or less is determined by evaporating 1.5 mL of solvent and comparing to the result of

1.5 mL of 5 ppm standard. If the baseline is applied, acceptance criteria of 5 ppm above baseline is determined by evaporating 1.5 mL of solvent and comparing to the result of 1.5 mL of unused solvent (baseline), followed by 1.5 mL of 5 ppm standard.

D.4 Significance and use.

D.4.1 The quantitative cleanliness standard for systems cleaned as specified in this standard generally applies to hydrocarbon non-volatile residues. However, this method does not differentiate between hydrocarbon based products (such as TEP 2190 oil) and fluorocarbon based products (such as Krytox 240AC grease). Additionally, this method is not sensitive to small quantities of particulate.
