Foreword
This document is drafted in accordance with GB/T 1.1-2020 "Directives for
standardization - Part 1: Rules for the structure and drafting of standardizing
documents".
This document replaces GB/T 16754-2008 "Safety of machinery - Emergency
stop - Principles for design". Compared with GB/T 16754-2008, in addition to
structural adjustments and editorial changes, the main technical changes are
as follows:
- Add the terms "emergency stop equipment", "span of control of emergency
stop device(s)", "protective shroud", "emergency situation" and "operator
control station" and their definitions (see 3.2, 3.6, 3.7, 3.8 and 3.9);
- Clarify and refine the safety requirements of the emergency stop function;
add the requirements for the span of control of emergency stop device (see
4.1; 4.1 of the 2008 edition);
- Modify the safety requirements of emergency stop device (see 4.3; 4.4 of
the 2008 edition);
- Add requirements for prevention of unintended actuation of an emergency
stop device (see 4.5);
- Add requirements for portable operator control stations (see 4.6).

Safety of machinery - Emergency stop function -
Principles for design
1 Scope
This document specifies functional requirements and design principles for the
emergency stop function on machinery, independent of the type of energy used.
This document apply to all machines, with exception to:
- machines where an emergency stop would not reduce the risk;
- hand-held or hand-operated machines.
This document does not deal with functions such as reversal or limitation of
motion, deflection of emissions (e.g. radiation, fluids), shielding, braking or
disconnecting, which can be part of the emergency stop function.
Note: The requirements for the realization of the emergency stop function based on
electrical/electronic technology are described in IEC 60204-1.
