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

EXAMPLE 6 - PHYSICAL CHARACTERISTICS

Performance specifications may include physical characteristics such as dimensions, weight, or anthropomorphic data as requirements in order to ensure needed physical interface or interoperability with other systems, equipment, components, or the human form. MIL-PRF-

32076, Unitization of Ammunition, covers unitization requirements for packaged ammunition. Shown below are the pallet dimensions, which are essential performance requirements to enable standard forklift trucks to pick up the ammunition pallets. This performance specification can be viewed in its entirety on the ASSIST database at https://assist.daps.dla/quicksearch/.

3.4.3 Pallet. The following requirements pertain to the interfacing of the pallet with existing material handling equipment in the DOD/NATO inventory. Alternatively, wood pallets conforming to ASME Part Number MH1/9-11 BW 4048P may be used in lieu of the requirements of this paragraph.

3.4.3.1 General.

3.4.3.1.1 Size. Pallet size shall be 1016 mm in length and 1219 mm in width, plus or minus 6 mm. Pallets of sizes other than 1016 mm in length and 1219 mm in width shall not be used unless first authorized by the procuring activity.

3.4.3.1.2 4-way entry. Full 4-way entry capability of the pallet shall be provided.

3.4.3.1.3 Bottom surface. The load-bearing surface in contact with the ground (pallet footprint)

shall be a minimum of 40 percent of the top deck area.

3.4.3.1.4 Forklift tine opening. The forklift slots shall be a minimum of 89 mm in height and a minimum of 254 mm in width, in two places, on all four sides of the pallet.

3.4.3.1.5 Height. The pallet height shall be 140 mm maximum.

3.4.3.1.6 Flatness. When the pallet bottom is placed on a flat surface, the pallet top shall not vary more than 6 mm from the average pallet height.

3.4.3.1.7 Squareness. The difference in the length of two diagonal corners shall not exceed 19 mm.

3.4.3.1.8 Wings. Width of the wings shall not be less than 64 mm.
