Overview

EN 4819:2012 - "Aerospace series - Contact Memory Button (CMB) tags intended for aircraft use" is a CEN standard that defines minimum requirements, qualification and documentation for battery‑free Contact Memory Button devices used on aerospace and defence vehicle parts. It is intended for permanently‑affixed CMBs used primarily during ground operations (read/write restricted in flight) and provides guidance for manufacturers, purchasers and certification authorities.

Key topics and technical requirements

• Device concept: CMB is a battery‑free, inert read/write memory button accessed with a momentary electrical button link. The standard does not cover the button link itself.
• Performance & life:
  • Data stability: minimum 20 years (or as required by the part lifecycle).
  • Life limit: CMB life must match the host part; procedures for data refresh and replacement reference ATA SPEC 2000 Chapter 9‑5.
• Environmental & mechanical:
  • Operating temperature: ‑55 °C to 125 °C; Storage: ‑65 °C to 150 °C.
  • Pressure: 50 hPa to 2 000 hPa.
  • Vibration: 10 G RMS; Impact: saw tooth 20 g‑Pk, 11 ms; Sustained acceleration: ±10 g‑Pk.
  • EMI/EMP/Magnetic/Gamma resilience: no data loss when exposed to 200 V/m RF, EMP levels 5.8 / 26.7 / 55.0 kV/m, 8 000 gauss magnetic flux, and 75 Krads (60Co) gamma radiation.
  • Environmental testing to consider: EUROCAE ED‑14 / RTCA DO‑160 or MIL‑STD‑810 (altitude, temperature, humidity, salt fog, dust, immersion, shock, vibration, ESD, etc.).
• Attachment & integration: Permanently affixed via mechanical fasteners, adhesive bonding or embedding; installation processes must address safety and minor‑change certification considerations.
• Data & interfaces:
  • Support for general file types (.pdf, .jpg, .doc, etc.) and firmware updates.
  • Manufacturers must supply outline drawings, pin‑outs, electrical characteristics and declared bus/protocol information.
  • Open file management and structure recommended; reference ATA SPEC 2000 Annex 11.
• Security: Support for encrypted storage, security protocols and unique identifiers for CMB, button link and related components.

Applications and users

• Primary users: CMB manufacturers, aircraft OEMs, maintenance/repair/overhaul (MRO) organizations, fleet operators, defence contractors and procurement/specification engineers.
• Typical applications: configuration management, component identification, asset tracking and traceability, inspection & maintenance records, calibration data management, retrofit marking for new or in‑service aircraft.

• EUROCAE ED‑14 and RTCA DO‑160 (environmental testing)
• MIL‑STD‑810 (environmental test methods)
