APPENDIX D

ANALYSIS OF HYDROCARBON OIL AND GREASE IN HCFC-225s SOLVENT BY INFRARED SPECTROSCOPY

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 determining hydrocarbon oil and grease in dichloropentafluoropropane (HCFC-225s) solvent extract by Fourier transform infrared (FTIR)

spectrophotometric analysis. This procedure is based on ASTM D 3921.

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 listed in the issue of the Department of Defense Index of Specifications and Standards (DoDISS) and supplement thereto, cited in the solicitation (see 6.2).

SPECIFICATIONS

DEPARTMENT OF DEFENSE

MIL-L-17331 - Lubricating Oil, Steam Turbine and Gear,

Moderate Service.

(Unless otherwise indicated, copies of the above specifications, standards, and handbooks are available from the Standardization Document Order Desk, 700

Robbins Avenue, Building 4D, Philadelphia, PA 19111-5094.)

D.3 PROCEDURE

D.3.1 Summary of test method. Solvent extract is examined by infrared spectroscopy to measure the amount of hydrocarbon oil and grease.

D.4 Significance and use.

D.4.1 This test procedure provides a method to quantitatively measure hydrocarbon oil and grease in HCFC-225s when used as a final oxygen cleaning solvent or when used to extract hydrocarbon oil and grease from an inorganic aqueous final cleaning solution.

D.4.2 This procedure is calibrated to measure hydrocarbon oil and grease at concentrations from 2 mg/L to 10 mg/L. To accurately measure higher concentrations, calibrate the procedure in accordance with ASTM D 3921.
