DATA PROCESSING WORK STATIONS
1. SCOPE: This specification establishes requirements for desk like work stations designed for use in data processing environments. Two (2) work surface sizes, two (2) working heights, and a variety of modular components are specified to provide flexibility in selecting a work station that best meets the user's needs. Bi-level work surfaces are not included in this specification.
2. CLASSIFICATION: Work stations furnished under this specification shall be classified by type, size, height, style, and color.
2.1. Type: Stations shall be classified by type as specified in Table 1.
|WS||Data Processing Work Station|
2.2. Size: Units shall be classified by size according to the dimensions of the work surface as specified in Table 2.
|Size||Dimensions (width x depth) ± 1/2"|
|48.00||48" x 30"|
|60.00||60" x 30"|
2.3. Height: Stands shall be classified by height according to the height of the work surface above the floor as specified in Table 3. Height is measured with all of the leveling glides set at their lowest adjustment.
|M||Machine (keyboard) height||26-1/2"|
2.4. Style: Units shall be classified by style according to the modular components with which the unit is equipped. Two-digit style designations shall be as shown in Table 4, with the first digit indicating the left hand component and the second digit indicating the right hand component. Style designation digits shall be in accordance with the Style Designation Code. Forty-eight inch (48") wide units may be equipped with only one (1) component, mounted either left or right. Therefore, style designations for these units must have an "O" as either the right digit (indicating no left hand component) or the second digit (indicating no right hand component). Sixty inch (60") wide units may be equipped with either one (1) or two (2) components. When Style Designation Code "2" or "3" is specified, the utility drawer may be a pedestal drawer or a center drawer, whichever is the manufacturer's standard practice.

The guarantee shall be in accordance with the manufacturer's standard warranty, except in no event shall such coverage be for less than one (1) year on the finished product or any component. Defective units shall be repaired or replaced during the warranty period at no cost to the State of Texas for parts or labor.
Note: Vendor shall bear all shipping and handling charges incurred during warranty period if a defective unit must be returned to a manufacturer's service center for repair or replacement.
7. SAMPLES: Unless otherwise specified in the Invitation for Bids, no prepurchase samples shall be required. Samples tested shall be taken from regular orders.
8. TESTING: Testing shall be done by or at the direction of, the Commission and/or the receiving State agency. Tests shall be performed on products from shipments to ordering agencies. In the event products tested fail to meet or exceed all conditions and requirements of this specification, the cost of the samples used and the cost of testing shall be borne by the supplier.
8.1. TESTS: All tests shall be performed with the leveling glides installed. Leveling glides shall be adjusted to the midpoint of the adjustment range. All tests shall be performed under conditions of normal room temperature and relative humidity. Products shall be tested by the following or approved equally applicable procedures:
8.1.1. Work Surface Flatness Test: This test shall be performed along both diagonals of the work surface. The test unit shall be placed on a flat surface. A steel straight edge longer than the diagonal length of the work surface shall be placed along each diagonal in turn. The straight edge shall be held firmly against the surface at one (1) corner and the surface shall be examined along the entire length of the straight edge for warps, bows, buckles, and ripples. Any gap between the work surface and the straight edge shall be measured. The results shall be no greater than 0.0625" as required in Paragraph 126.96.36.199.
8.1.2. Static Load Test: The stand shall be placed on a flat surface. A weight of three-hundred pounds (300 lbs.) shall be applied for fifteen (15) minutes to a twelve inch (12") diameter circular area. The center of the weight application area shall be located six-and-one-half to seven inches (6-1/2" to 7") from the front edge at the midpoint of the work surface width. The deflection of the top under the applied weight shall be measured and expressed as a percentage of work surface width using the following formula:
% deflection = measured deflection x 100
work surface width
The applied weight shall then be allowed to remain on the work surface for twenty-four (24) hours. After 24 hours, the weight shall be removed and the work surface shall be allowed to stabilize for two (2) hours. Any remaining deflection shall be considered as permanent set. The permanent set shall be measured and expressed as a percentage of the work surface width using the following formula:
% permanent set = measured permanent set x 100
work surface width
The percent deflection, the percent permanent set, and the structural integrity of the unit shall be examined for compliance with Paragraph 188.8.131.52. and Table 6.
8.1.3. Racking Test: The work station shall be placed in its in use position on a hard flat surface, and the distance between the inside surfaces of the leg uprights at the base shall be measured. One (1) end of the work station shall then be raised until the stand is approximately balanced on the opposite leg assembly. A support shall be placed beneath the raised leg assembly to brace the work station as nearly as possible in the balanced position. When the work station is braced in position, the lowermost corner of the raised leg assembly shall be not more than 0.25" lower than when the work station is perfectly balanced. The work station shall be left in this position for twenty-four (24) hours. After 24 hours, the above procedure shall be repeated on the opposite end for another 24 hours. The work station shall then be lowered to its in use position and the distance between the uprights shall be measured as before. Any change in this distance from the initial measurement shall be considered as permanent set. The permanent set and the structural integrity of the station shall be examined for compliance with the requirements of Paragraph 184.108.40.206. and Table 6.
8.1.4. Shock Test: The work station shall be placed in its in use position on a flat, level concrete floor. One (1) end of the work station shall be raised until the bottoms of the glides are a minimum of twelve inches (12") above the floor. The raised end shall then be released to free fall to the floor. This procedure shall then be repeated on the opposite end. After both ends shave been dropped, the glides and the structural integrity of the work station shall be examined for compliance with the requirements of Paragraph 220.127.116.11.
8.1.5. Drawer Cycle Test: This test shall be performed on each drawer while the pedestal is mounted to the work station. The test unit shall be placed on a flat, level surface in its normal in use position. The test drawer shall be loaded with an evenly distributed load of typical filing material in accordance with Table 7.
DRAWER LOADING REQUIREMENTS
|Drawer Type||Load Requirement|
|Utility Drawer||0.5 lb/inch of depth (10 lb minimum)|
|Storage Drawer||1.5 lb/inch of depth (30 lb minimum)|
|Letter/legal File Drawer||2.0 lb/inch of depth (40 lb minimum)|
|DP Document File Drawer||2.5 lb/inch of depth (50 lb minimum)|
9. INSPECTION: Inspection shall be done by, or at the direction of the Commission either at the destination or at the place of manufacture.
10. PACKING: Packing for shipment shall be in accordance with the manufacturer's standard practice and in a manner readily accepted by common carriers engaged in interstate commerce.
