I would recommend looking at A17.1-8.10.3 acceptance inspection and tests of hydraulic elevators. Maybe you can find the code references that you’re looking for. Not sure if it’s a new job or what code version you’re trying to comply with.
I remember fighting with a traction car trying to get original floor to floor times for the consultants report. Realizing that preopening had been taken off years earlier, I put it back on for the customer to ride. After taking it for a trip the customer said “ put it back to normal and we’ll take care of the consultants”
I agree with others that sometimes it’s hard on the equipment and ride quality trying to shave off another second. For what?
