Introduction

Core changes in the standard revision

Items	2006 Edition	2022 Edition
Terminology system	6 items	15 new items including push rod lock
Structural classification	Not clear	Full-height enclosed/non-enclosed, half-height shielding door
Fully automatic operation	Not involved	New linkage control and SIL2 safety level requirements
Maintenance cycle	Not specified	Specify the system from daily inspection to annual inspection

Clause 6.2.3 stipulates the requirements for kinetic energy control of sliding doors:

Maximum kinetic energy throughout the entire journey ≤10J (equivalent to the energy of a 1kg object falling from a height of 1m)
Kinetic energy of the last 100mm of travel ≤1J (achieved through deceleration curve)
Anti-pinch force ≤150N (equivalent to the pressure of a 15kg object)

In actual applications, it needs to be implemented in conjunction with the speed curve adjustment function of the door controller.

Clause 5.6.20 specifies for the first time the special requirements for fully automatic lines:

Operation and maintenance optimization: Establish a predictive maintenance system based on the MTBF indicator, focusing on:
