Describes requirements and methodology for the measurement and reporting of lift ride quality during lift motion.

This International Standard specifies requirements and methodology for the measurement and reporting of lift ride quality during lift motion. It does not specify acceptable or unacceptable ride quality.

NOTE Lift performance parameters are often referenced in conjunction with lift ride quality. Parameters relevant to lift performance include jerk and acceleration. This International Standard defines and uses performance parameters where they are integral to the evaluation of ride quality.
