ISO 9379:2005

Overview

ISO 9379:2005 defines standardized test methods to measure the operating forces for pedestrian doorsets, including hinged, pivoted, and sliding doors equipped with latches. Developed by ISO Technical Committee ISO/TC 162, this standard specifically addresses the forces required to open and close manual doors, as well as to engage, release, lock, and unlock door hardware using keys or handles. Applicable across all door materials, ISO 9379:2005 excludes doors with self-closing devices actively engaged or those fitted with specialized hardware like emergency exit devices.

This international standard ensures reliable and repeatable testing to determine minimum operating forces, facilitating the design, manufacturing, and quality control of doors and hardware systems aimed at ease of use and safety for pedestrian access.

Key Topics

• Scope and Applicability:

  • Applies to manually operated hinged, pivoted, and sliding pedestrian doorsets with latches.
  • Not suitable for self-closing doors or special hardware such as emergency exits.
  • Relevant to doorsets made from any material.

• Test Principle:

  • Measurement of minimum force or torque needed to operate door hardware (locks, latches, handles).
  • Includes forces to open, close, lock, unlock, engage, and release doors or safety devices.

• Test Apparatus Requirements:

  • Use of support frames that do not affect results.
  • Application of forces incrementally (up to 1.0 N increments) without shock, via weights and pulleys or torque meters.
  • Accurate measurement devices maintaining ±5% accuracy.

• Testing Procedures:

  • Dynamic closing force: measuring the minimum force to close and engage latches or personal safety devices.
  • Hardware operation force: determining forces/torques for locking/unlocking and unlatching.
  • Commencing and maintaining motion: measuring forces required to start and sustain door movement.
  • Multiple repetitions (minimum three) for each test, averaging results for accuracy.

• Environmental Conditions:

  • Tests conducted at temperatures between 10°C and 30°C and relative humidity between 25% and 75%.
  • Specimens must be fully operable and conditioned to test environment prior to testing.

• Reporting:

  • Detailed reporting including test conditions, specimen descriptions, test methods used, and measured results in Newtons (N) and Newton metres (Nm).
  • Inclusion of drawings, product designations, and observations to support reproducibility and certification.

Applications

ISO 9379:2005 is invaluable for manufacturers, product designers, testing laboratories, and regulatory bodies involved with door safety and usability. Its practical applications include:

• Door Hardware Design: Optimizing door handle, latch, and lock mechanism designs to ensure ease of use and compliance with ergonomic standards.
• Quality Assurance: Verifying force thresholds during production to maintain consistent product performance and user safety.
• Building Compliance: Supporting certification processes and regulatory approvals by providing standardized test evidence of operating forces.
• Accessibility Compliance: Ensuring doors meet accessibility requirements, reducing opening forces to accommodate users with disabilities.
• Material Testing: Evaluating how different materials affect door operation forces, allowing for material selection aligned with performance goals.

Related Standards

• EN 12046-2:2000: The European standard equivalent to ISO 9379:2005 focusing on similar test methods for door operating forces.
• prEN 12519:1996: Establishes terminology for doors and windows, supporting consistency in definitions relevant to this testing.
• ISO 16283 & ISO 21542: Standards related to building hardware and accessibility requirements which may reference operating force considerations.
• ISO/IEC Directives Part 2: Governs the drafting and approval processes for international standards like ISO 9379.

By adopting ISO 9379:2005, stakeholders in the building and construction industry gain a robust methodology that advances product reliability, user safety, and regulatory compliance in door operation testing. This ensures doorsets are functional, user-friendly, and accessible to all pedestrians in various environments.
