5. CURRENCY OF MODELS: Products delivered under this specification shall be produced in the current year, unless otherwise specified in the Invitation for Bids.

6. TESTING: Testing shall be done by or at the direction of the Commission and/or the ordering State agency. Test shall be performed on products after delivery and installation. In the event products tested fail to meet or exceed all conditions and requirements of this specification, the cost of the testing shall be borne by the supplier. The products furnished under the specification shall be tested by the following methods or approved equally applicable procedures:

6.1. Lifting Capacity: Determine the concentric loading capacity by securely loading one superstructure of the lift with the minimum rated capacity (8,000 pounds for Size I and 12,000 pounds for Size II). Distribute this load evenly over the center of the post. Raise the load to its maximum height and measure the time from the opening of the oil control valve until the automatic non-rotation leg locks the lift at the extended position. Failure of the lift to raise the rated capacity load with 100 seconds constitutes failure of the lift (See Paragraph 3.2.).

Measure the plunger travel and the floor-to-vehicle contact point. Compare with the requirements of Paragraph 3.2.3.

Lower the lift and measure the time required for a point on the lift (or automobile) to travel a measured distance. For example, measure the time required for the lowest point on a tire to travel from the fully extended position to contact with the floor. Accurately calculate this speed by dividing the distance traveled by the time. Compare with the requirements of Paragraph 3.2.

Raise the load a second time and release the oil control lever at approximately the midpoint of lift travel to test the proper operation of the automatic cutoff switch. After a period of at least five (5) seconds, continue rasing the lift to its fully extended position. Lower the lift and again observe the operations of the automatic cutoff switch. After a period of at least five (5) seconds, lower the lift. Failure of the lift to hold the rated capacity load in both of the above positions for a least five (5) seconds constitutes failure of the lift.

Repeat the above procedures for the other superstructure. Determine compliance with the various requirements as above.

6.2. Safety Control: Drain the oil supply to a level less than three inches (3") or 10% of the capacity, whichever is smaller. Attempt to raise the hoist. Failure of the safety device to prevent the raising of the hoist constitutes failure of the lift.

6.3. Measure the force required to operate the various manually adjustable assemblies. Determine compliance with the requirements of Paragraph 3.3.).

7. PACKAGING: Lifts shall be packaged in accordance with the best recognized commercial practices in a manner readily acceptable by common carriers engaged in interstate commerce.

8. MARKING AND LABELING:
