SD-15 Guide For Performance SpecificationsThis document provides guidance information on performance specifications focusing primarily on stating requirements in performance terms and ensuring that sufficient verification means are included in the specification to evaluate conformance. While the focus of this document is on defense specifications developed under DoD 4120.24-M, Defense Standardization Program DSP Policies and Procedures, the principles and techniques can also be applied to program unique performance specifications, performance-based purchase descriptions, commercial item descriptions, or any other type of procurement specification. This guide is intended to supplement the format and content requirements for writing performance specifications found in MIL-STD-961, Defense and Program-Unique Specifications Format and Content.

3.7.3 Endurance. The Tactical Sling shall not melt, deform or become unserviceable in performance after firing a total of 1260 rounds with a M16 rifle.

3.7.4 Workmanship. Finished items and parts shall not exhibit poor material and processing such as seams, laps, laminations, cracks, visible steps, sharp edges, nicks, scratches, burrs, deformations, and missing operation which may affect serviceability, functioning, operations, appearance or safety. Fins and other extraneous metal shall be removed from cast or forged parts. Hammering to shape, salvage operations (including repair by welding) or other similar practices shall not be permitted without prior approval of contracting officer.
