Which Safety Standards are important?

Well, all safety standards are important to someone in some project. But generally, a set of only 11 standards contain solutions to 80% of the safety issues coming up. However, it is good to understand the structure of the machinery safety standards system.


    • EN ISO 12100

      General principles for design - Risk assessment and risk reduction

      Machine safety “Bible”, contains all the important definitions, basic rules for selection of safety measures, and detailed instructions for risk assessment

    • EN ISO 13857

      Safety distances to prevent hazard zones being reached by upper and lower limbs

      Determines height of fencing, size of access openings and corresponding safety distances

    • EN ISO 13854

      Minimum gaps to avoid crushing of parts of the human body

      Defines size of important body parts like fingers, hands, feet, head etc. for protection from crushing (previously EN 349)

    • EN ISO 13851

      Two-hand control devices - Principles for design and selection

      Rules for design of controls requiring simultaneous pressing of two buttons to start and run a hazardous function

      (previously EN 574)

    • EN ISO 14120

      Guards - General requirements for the design and construction of fixed and movable guards

      Rules for design of safety covers, fences doors etc.

    • EN ISO 14119

      Interlocking devices associated with guards - Principles for design and selection

      Types and selection of safety switches, rules on how manipulation can be prevented

    • EN ISO 13855

      Positioning of safeguards with respect to the approach speeds of parts of the human body

      Basics and formulas for design of light curtains, laser scanners and two-hand control applications

    • EN ISO 13850

      Emergency stop - Principles for design

      Rules for control elements and definition of the “stop categories”

    • EN ISO 13849-1/-2 Safety-related parts of control systems Basics for design of reliable control circuits such as for door interlocking and monitoring, formulas and methods, part 2 covers verification and validation of safety systems

    • EN 60204-1 Electrical equipment of machines - Part 1: General requirements The electrical safety “Bible” for machine manufacturers

    • EN ISO 11161

      Integrated manufacturing systems - Basic requirements

      Design principles for systems including machine tools, conveyors and robotics at the same time, rules for subdivision into several hazard areas



From 29 December 2009, the Machinery Directive 2006/42/EC is valid.
Some of the changes in brief include: 
Machines defined as “non-independent machine” (2B machine) are now defined as “partly completed machinery”. The requirements for these machinery types have also been raised, e.g. a documented risk analysis must be carried out.
