Safety of machinery - Part 3610: Conveyors - General requirements
Provides guidance and clarity in applying the principles articulated in the AS/NZS 4024 series of standards to conveyors. It sets out the minimum lifecycle safety requirements for conveyor systems and is intended to be used in conjunction with other conveyor Standards in the AS 4024 series by all persons that design/modify, manufacture, supply, install, commission, operate, maintain or dismantle conveyor systems. The objective is to protect workers and other persons against harm to their health, safety and welfare through the elimination or minimization of lifecycle risks associated with conveyor systems.
