Overview

EN 60947-5-5:1997/A2:2017 (IEC 60947-5-5:1997/A2:2016) is a CENELEC amendment covering electrical emergency stop devices with mechanical latching function used in low-voltage switchgear and controlgear. It updates definitions, colour/symbol requirements, contact action rules and normative references, and is intended to support conformity with EU safety directives (see Annex ZZ). The amendment was approved in 2016 and published as EN A2 in 2017.

Key topics and requirements

• Scope: Special requirements for emergency stop pushbuttons with mechanical latching; other relevant requirements are referenced to EN/IEC 60947-1 and EN/IEC 60947-5-1.
• Colour and symbol:
  • Actuators (buttons) shall be red; background, if present, yellow.
  • Use graphical symbol IEC 60417-5638 for emergency stop where needed.
• Contact action:
  • All normally closed contact elements of an emergency stop device must have a direct opening action (formerly called “positive opening action”) as defined and tested in Annex K of IEC 60947-5-1:2016.
• Definitions updated: Terms such as emergency stop device, actuator, actuating system, rest/actuated position, resetting and direct opening action are clarified or revised.
• Testing & environmental references: Normative references updated to modern environmental tests (IEC 60068 series), IEC 60947-1 and IEC 60947-5-1, IEC 61310-1 and ISO 13850:2015 (emergency stop principles).
• Noise: Amendment explicitly states it does not address noise emission of these devices (not considered a relevant hazard).
• Regulatory linkage: Annex ZZ explains the relationship to Directive 2014/35/EU (Low Voltage Directive) and notes presumption of conformity when the standard is cited in the Official Journal.

Applications

• Safe design and specification of emergency stop pushbuttons and mechanically latching E‑stop assemblies in:
  • Industrial machinery and manufacturing lines
  • Control panels and operator stations
  • Mobile equipment and safety interlocks
• Selection, testing and marking of devices by manufacturers, design engineers, machine builders, safety specialists, testing laboratories and notified bodies for compliance with low-voltage safety requirements.

Who should use this standard

• Controlgear and switchgear manufacturers manufacturing E‑stop devices
• Machine designers integrating emergency stop circuits
• Safety engineers verifying functional safety and emergency stop behavior
• Compliance officers seeking presumption of conformity with EU directives
• Test laboratories performing type and environmental testing per IEC references

Related standards

• EN/IEC 60947-1 (general rules for low-voltage switchgear)
• EN/IEC 60947-5-1 (electromechanical control circuit devices)
• ISO 13850 / EN ISO 13850 (Emergency stop - principles for design)
• IEC 60068 series (environmental testing)
• IEC 61310-1 (indication, marking, actuation)

(informative)
Relationship between this European standard and the safety objectives of
Directive 2014/35/EU [2014 OJ L96] aimed to be covered

This European standard has been prepared under a Commission’s standardisation request relating to
harmonised standards in the field of the Low Voltage Directive, M/511, to provide one voluntary means
of conforming to safety objectives of Directive 2014/35/EU of the European Parliament and of the
Council of 26 February 2014 on the harmonisation of the laws of the Member States relating to the
making available on the market of electrical equipment designed for use within certain voltage limits
[2014 OJ L96].
Once this standard is cited in the Official Journal of the European Union under that Directive,
compliance with the normative clauses of this standard given in Table ZZ.1 confers, within the limits of
the scope of this standard, a presumption of conformity with the corresponding safety objectives of
that Directive, and associated EFTA regulations.

Only special requirements for emergency stop pushbuttons with latching function are covered by this
standard. All other relevant requirements are given in EN 60947-1 and EN 60947-5-1 as described in
the foreword.
WARNING 1: Presumption of conformity stays valid only as long as a reference to this European
standard is maintained in the list published in the Official Journal of the European Union. Users of this
standard should consult frequently the latest list published in the Official Journal of the European
Union.
