General Information

Abstract

This European Standard specifies requirements for performance and testing of mechatronic padlocks (MPs) and their keys and/or electronic keys.
It establishes categories of use based on performance tests and grades of security based on design requirements and on performance tests that simulate attack.  If the design incorporates mechanical security means in addition to the mechatronic means, these are also tested.
This European Standard does not cover any other element of a security system, other than those directly involved in the control of a padlock.  
This European Standard does not cover the physical testing of multi-function devices such as Smartphones that may be used as part of the control system.

Overview

EN 16864:2017 - Building hardware - Mechatronic padlocks - Requirements and test methods is a European Standard published by CEN that defines performance, testing and classification for mechatronic padlocks (MPs) and their electronic keys. The standard specifies functional, environmental and mechanical requirements, establishes use categories and security grades, and sets repeatable test methods that simulate attack (both mechanical and electronic) to verify resistance and durability. EN 16864:2017 focuses strictly on elements directly involved in padlock control and does not cover broader security systems or testing of multi‑function consumer devices (e.g., smartphones).

Key topics and requirements

  • Scope and definitions: Clear terms for MPs, electronic keys, audit trail, whitelist, mean time to compromise (MTC), spoofing, brute‑force and dictionary attacks.
  • Categories of use and security grades: MPs are classified by performance tests (operation, key strength, environmental resistance) and by attack resistance (design and simulated attacks).
  • Mechanical and mechatronic tests: Includes torque, key/knob operation, shackle pull, twist and cut tests, impact, drilling and sawing resistance. Test rigs and tool sets are defined for reproducibility.
  • Environmental tests: Vibration, shock, cold/heat, damp heat and corrosion resistance are specified to assess durability in real conditions.
  • Electronic security tests: Requirements for electronic code variation, resistance to spoofing, brute‑force and cryptographic attacks, time‑zone and audit‑trail functionality, and electronic key robustness.
  • Marking and documentation: Requirements for manufacturer marking and information to support correct selection and installation.
  • Reproducible test procedures: Detailed sampling, assessment and pass/fail criteria to ensure consistent certification across laboratories.

Applications and who uses this standard

EN 16864:2017 is applicable to:

  • Manufacturers of mechatronic padlocks for product design, quality control and market compliance.
  • Independent test laboratories that certify padlocks to European performance and security grades.
  • Security consultants, procurement teams and facility managers selecting padlocks for access control, asset protection, transport, storage and site security.
  • Architects and specifiers integrating secure locking hardware into building designs.
  • Regulators and certification bodies assessing conformity with European norms.

Practical benefits include verified attack resistance, predictable lifecycle behavior in harsh environments, clear security grading for procurement, and standardized test evidence for claims about audit trail, time‑based access and electronic key resilience.

Related standards (if applicable)

EN 16864 references and complements other standards used in testing and conformity:

  • EN 12320:2012 (padlocks - mechanical performance)
  • EN 1670:2007 (corrosion resistance)
  • EN 60068 series (environmental testing: vibration, shock, temperature, humidity)
  • EN 60529 (IP protection ratings)
  • Relevant EN/ISO screw and drill standards used in test setups

Keywords: EN 16864:2017, mechatronic padlocks, padlock testing, security grades, electronic keys, audit trail, attack resistance, building hardware.
