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.

Performance Specification Guide SD-15

4.1 Design verification. When specified (see 6.2), design verification shall be performed by demonstration, examination and tests of all performance requirements as specified in table I.

4.1.1 Design verification rejection. If a sample fails to meet any specified performance requirement, the design shall be rejected.

4.2 First article inspection. When specified (see 6.2), first article inspection of sample items shall be executed by demonstration, examination and tests of all performance requirements in accordance with table I.

4.2.1 First article rejection. If any sample fails to comply with the specified performance requirements, the sample shall be rejected.

4.3 Conformance verification. When specified (see 6.2), conformance inspection of lot samples shall be accomplished by examinations, demonstrations and tests in accordance with table I.

4.3.1 Lot formation. Lot formation shall be in accordance with the lot formation requirement as specified in MIL-STD-1916.

4.3.2 Lot Rejection. If any sample fails to comply with the specified performance requirements, the lot shall be rejected.

4.4 Operating Verification

4.4.1 High ready position upon release. Verified by demonstration that the Tactical Sling

shall maintain the weapon orientation in the high ready position upon release. The Tactical Sling shall be mounted to the M16 and M4 along with the ancillary equipment during this verification process.

4.4.2 Low ready position upon release. Verified by demonstration that the Tactical Sling shall maintain the weapon orientation in the low ready position upon release. The Tactical Sling shall be mounted to the M16 and M4 along with the ancillary equipment during this verification process.

4.4.3 Adjustment ability. The Tactical Sling shall demonstrate that it will allow the

Warfighter to adjust for multiple fighting and carrying positions as referenced in chapters 4 and 7 of the FM 3-22 manual. The Tactical Sling shall be mounted to the M16 and M4 along with the ancillary equipment during this verification process.

4.5 Interface and interoperability verifications.

4.5.1 Webbing. The width of the Tactical Sling belt shall be measured using SMTE and shall be visually inspected to ensure it is made of a soft web-like synthetic material.
