scope:

This specification covers the general requirements for insulated binding posts and uninsulated binding posts with insulated and uninsulated caps.

Items procured under this specification shall be identified by the following specification based part number:

The part number specification/specification sheet identifier shall consist of the letter "M", the digits of the specification number "55149", a slash (/), and a two digit numeral which denotes the slash number of the specification sheet covering the item being identified. When the slash number is less than 10, the first digit shall be a zero. Example: M55149/01 is the specification/ specification sheet identifier for this specification and for specification sheet MIL-P-55149/1.

The non-turn feature code is a single letter code which identifies the method used to prevent the item from turning when installed. The non-turn feature codes are in Table 1. Beneficial comments (recommendations, additions, deletions) and any pertinent data which may be of use in improving this document should be addressed to: US Army Laboratory Command, ATTN: SLCET-RS, Fort Monmouth, NJ 07703-5000 or by using the self addressed Standardization Document Improvement Proposal (DD Form 1426) appearing at the end of this document or by letter. TABLE I - Nonturn feature.

Symbol Nonturn feature ------------------------------------------------------------------ D - - - - Dowel F - - - - Flatted boss K - - - - Knurled base N - - - - Nonturn feature not furnished

The insulation code is a single - letter code which identifies the insulation features of binding posts covered by this specification. The insulation codes are listed in Table II. TABLE II - Insulation.

Symbol Insulation -------------------------------------------------------------------------------- A - - - - Insulated B - - - - Uninsulated with uninsulated cap C - - - - Uninsulated with insulated cap

Dash numbers are numbers assigned to binding posts on the applicable specification sheets so every different binding post will have a unique identification number. Dash numbers are usually assigned in sequence (1,2,...) for each different combination of features. A dash number shall be assigned even when there is only one item identified on a specification sheet. When the numbers listed on a specification sheet are less than 10, the first digit in the part number shall be a zero. For example, item number shall be identified with the dash number "01".
