Safety of machinery Part 1603: Design of controls, interlocks and guards – Prevention of unexpected start-up

inactive
Organization: SNZ
Publication Date: 29 July 2019
Status: inactive
Page Count: 22
scope:

This document specifies requirements for designed-in means aimed at preventing unexpected machine start-up (see 3.2) to allow safe human interventions in danger zones (see Annex A).

This document applies to unexpected start-up from all types of energy source, i.e.:

- power supply, e.g. electrical, hydraulic, pneumatic;

- stored energy due to, e.g. gravity, compressed springs;

- external influences, e.g. from wind.

This document does not specify performance levels or safety integrity levels for safety-related parts of control systems. While available means to prevent unexpected start-up are identified, this document does not specify the means for the prevention of unexpected machine start-up for specific machines.

NOTE A type-C standard can define the required means for the prevention of harm arising from unexpected start-up. Otherwise, the requirements for a specific machine need to be determined by risk assessment outside the scope of this document.
