What is this standard about?

BS EN ISO 14120:2015 outlines requirements for the design, construction, application and testing of fixed and movable guards.

Who is this standard for? 

  • Machine users
  • Machine designers
  • Builders, installers and integrators
  • Health and safety inspectors and regulatory bodies

Why should you use this standard? 

This standard aims to protect people from mechanical hazards relating to fixed and moveable guards. Guards can help protect against dangers/accidents occurring with unintended access or ejected parts and substances. Guarding can also give protection against others hazards such as noise, fire, biological hazards and radiation.

What’s changed since the last update?

This international standard replaces BS EN 953 and ISO 14120:2002 as the standard for compliance with the EU's Machinery Directive and includes the following updates:

  • Definitions have been brought into line with BS EN ISO 21200. The figures showing examples of guards have been updated where appropriate
  • Clause 5 has been updated with new references to BS EN ISO 13855 and BS EN ISO 14119. Requirements on the removal of guards have been amended. Sub-clause 5.3.9  describes requirements for the removal of fixed guards only with a tool. In addition, there is a requirement that fixed guards be designed to prevent easy removal. Sub-clauses on climbing, retained fastenings, warning signs, colour and appearance have been added
  • Clause 6 has been amended and updated to better include cover combinations of different guards or of guards with other devices
  • Clauses on verification and validation have been introduced (Clause 7). This includes a table which outlines the safety requirements and/or measures by sub-clause
  • Two new informative annexes on test methods, one on projectile tests and the other on impact tests, have been added
