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 or casters 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 188.8.131.52.
9.3.2. 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") fro 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 stabilized for two (2) hours. Any remaining deflection shall be considered a 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 184.108.40.206. and Table 4.
9.3.3. Racking Test: the stand 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 stand shall then be raised unit the stand is approximately balanced on the opposite leg assembly. A support shall be placed beneath the raised lege assembly to brace the stand as nearly as possible in the balanced position. When the stand is raced in position, the lowermost corner of the raised leg assembly shall be not more than one-fourth inch (1/4") lower than when the stand is perfectly balanced. The stand shall be left in this position for twenty-four (24) hours. The stand 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 stand shall be examined for compliance with the requirements of Paragraph 220.127.116.11. and Table 4.
9.3.4. Shock Test: The stand shall be placed in its in use position on a flat, level concrete floor. One (1) end of the stand shall be raised until the bottoms of the glides or casters 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 have been dropped, the glides or casters and the structural integrity of the stand shall be examined for compliance with the requirements of Paragraph 18.104.22.168.
10. INSPECTION: Products furnished under this specification shall be inspected by, or at the direction of the Commission and/or the ordering State agency either at the destination or place of manufacture.
