    46、oducts, or by contacting the responsible packaging activity. 6. NOTES (This section contains information of a general or explanatory nature that may be helpful, but is not mandatory.) 6.1 Intended use. Waveguide flanges covered by this specification are intended for use as coupling devices for waveg

    47、uides and waveguide components used in military electronic equipment and systems. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-DTL-39000C 6 6.2 Acquisition requirements. Acquisition documents must specify the following: a. Title, number, and d

    48、ate of this specification. b. The specific issue of individual documents referenced (see 2.2). c. Whether flanges are to be annealed before finish machining (see 3.3.1). d. Packaging requirements (see 5.1). 6.3 Environmentally preferable material. Environmentally preferable materials should be used

    49、to the maximum extent possible to meet the requirements of this specification. As of the dating of this document, the U.S. Environmental Protection Agency (EPA) is focusing efforts on reducing 31 priority chemicals.
