6. NOTES

(This section contains information of a general or explanatory nature that may be helpful, but is not

mandatory.)

6.1 Intended use. The cords covered by this specification are used to make up combination

headset-microphone extension cords and microphone cords for installation in specific defense aircraft

with intercommunication sets. These cords are defense unique because they are configured for use

only in defense aircraft.

a. WM-85/U is used with plug connector U-94( ) U to make up combination headset-microphone

extension cords with portable microphone switch.

b. WD-34/U is used as a microphone cord with the M-3A/A, M-32( ) AIC, and M-33( ) AIC

microphones.

c. WF-5/U is used with jack U-61/U to make up headset-microphone extension cords.

d. WM-53/U is used with jack U-82/U to make up combination headset-microphone extension

cords with a portable microphone switch.

e. WF-14/U is used with jack U-92( )/U to make up combination headset-microphone extension

cords.

6.2 Acquisition requirements. Acquisition documents must specify the following:

a. Title, number, and date of this specification.

b. Type designation and PIN (see 1.2 and 1.2.1).

c. If required, the specific issue of individual documents referenced (see 2.2.1 and 2.3).

d. Whether first article inspection is required (see 3.1 and 4.4). Invitations for bids should

provide that the government reserves the right to waive the requirement for samples for first

article inspection for those bidders offering a product that has been previously acquired or

tested by the government, and that bidders offering such products who wish to rely on such

production or test must furnish evidence with the bid that prior government approval is

presently appropriate for the pending contract.

e. Packaging requirements (see 5.1). The cords should be furnished on spools, in spool or

reel-type packages, or on reels. Each spool, package, or reel should contain not less than

450 feet and not more than 550 feet. The maximum number of continuous lengths per spool,

package, or reel should be 3. The length of any one piece thereof should not be less than

50 feet.

6.3 Material handling and disposal. Caution should be taken during handling and disposal of all

insulation and jacket materials in accordance with ASTM C930 and FED-STD-313.
