Maximum depth of single row: Nominal shelf depth + 5/16 inch Maximum depth of a double row: Nominal shelf depth * 2 + 7/8 inch Maximum aisle length: (Nominal shelf width + 1-5/16 inch)

* shelving units in row + 2-7/8 inch

3.2.7. BACK PANELS

Back panels shall have either predrilled or punched mounting holes which match up to mating holes in the supporting posts.

Back panels shall be made of metal and shall fully enclose the back of the shelving unit from the floor to the top of the unit.

Overlapping of two or more back panels will be acceptable in lieu of one continuous panel from top to bottom for backs over 87 inches high. Back-to-back shelving units shall share a single, common back panel between each unit. The back panels shall be secured to the supporting posts. Shelves shall not be used to secure the back panels into position. Screws used to secure the back panel shall not prohibit the installation of shelves.

4. QUALITY ASSURANCE PROVISIONS

4.1. INSPECTIONS

The system shall be inspected to verify that it meets all the requirements of sections 1, 2, and 3 of this appendix and the Cover PD. These inspections shall be completed as part of the system checkout test and again as a part of the quality conformance test.

4.2. TEST

The following test shall be performed on the system as part of the system checkout test and again as a part of the quality conformance test.

No. Paragraph Description

1. 3.1. The shelving system shall be inspected to ensure capability of interfacing with supply personnel. If interface between supply personnel cannot be conducted in the aisles without damage to shelving units, property stored, equipment, or injury to personnel, the system shall fail.

FA860423RB005 ATTACHMENT 4 8

Shaw AFB, SC - App C - Page 7

2. 3.2.4.2. Four randomly chosen shelves shall be designated by the COTR. The distance from the top of each designated shelf to the top of the shelf above it shall be measured at the mid-point of the shelf and recorded as M1. The designated shelves will then be loaded uniformly with a load of 400 pounds and left for a minimum of 4 hours. The distance from the designated shelf to the top of the next shelf will be measured again and recorded as M2 to determine if the maximum deflection is less than 0.875 percent of the unsupported span.

The following formula shall be used to determine the deflection amount:

Deflection = [(M1 - M2) / 48] * 100 If the deflection is greater than 0.875 or if permanent deformation exists when the loads are removed, the system shall fail.

4.3. CERTIFICATIONS

The Contractor shall provide certification that the following requirements have been met. All certifications shall be provided in accordance with the Contract Data Requirements List.

No. Paragraph Certifications

1. 3.2.3. The Contractor shall certify that each load bearing component shall have minimum safety factor of 1.65 to 1.

2. 3.2.5.2. The Contractor shall certify that each supporting post has a minimum capacity of 1600 pounds based on 24 inch shelf spacing.
