Operational Forces for Doors

Standard: EN 12217:2005

Standard Information

  • Standard Number: EN 12217:2005
  • Title: Doors - Operating forces - Requirements and classification
  • Status: Current
  • Application: Manually operated pedestrian doors

Classification System

Force Classes

The standard defines four classes based on operating forces:

  • Class 0: No performance determined
  • Class 1: Light operational forces (up to 75N)
  • Class 2: Medium operational forces (up to 50N)
  • Class 3: Light operational forces with door closer (up to 25N)
  • Class 4: Very light operational forces (up to 10N)

Measurement Parameters

Forces are measured for:

  • Initial opening force
  • Maximum opening force
  • Closing force
  • Latching force
  • Key/handle operation force

Testing Methods

Testing procedures include:

  • Force measurement at different points
  • Dynamic force testing
  • Static force measurement
  • Operating mechanism assessment
  • Durability verification

Application Guidelines

Recommended Classes by Use

  • Class 1: Standard residential doors
  • Class 2: Public buildings, commercial use
  • Class 3: Schools, hospitals, elderly care facilities
  • Class 4: Accessible facilities, special needs applications

Influencing Factors

Key factors affecting operational forces:

  • Door weight and dimensions
  • Hardware selection and quality
  • Door closer specifications
  • Frame alignment
  • Environmental conditions
  • Maintenance status

Accessibility Considerations

  • Compliance with disability regulations
  • Ease of operation for all users
  • Emergency egress requirements
  • Special needs considerations
  • Safety features integration

Installation Requirements

  • Proper hardware mounting
  • Correct closer adjustment
  • Frame leveling and squaring
  • Regular maintenance schedule
  • Performance verification

Important Considerations:

  • Select appropriate class for intended use
  • Consider user demographics
  • Verify compliance with local regulations
  • Ensure proper maintenance procedures
  • Document testing and adjustments
