ISO 10327:2014

Overview

ISO 10327:2014 - Air cargo: Main deck containers - Design and testing defines the minimum design and operational testing requirements for general-purpose, base‑restrained main-deck air cargo containers intended for the main or upper deck cargo compartments of transport aircraft. It applies to containers that require airworthiness authority approval (certification) and is intended for use by airlines, shippers, manufacturers and certifying bodies.
Note: ISO 10327:2014 supplements - but does not replace - the performance/ultimate load testing requirements covered by ISO 21100 or (for older approvals) ISO 8097:2001. It also excludes lower-deck containers (≤ 1 625 mm / 64 in height) and certain air‑surface ULDs (see Related Standards).

Key topics and technical requirements

ISO 10327:2014 structures requirements across several practical areas:

• Container sizes and identification (Clause 3)
  • Defines nominal base sizes: A (2 235 × 3 175 mm / 88 × 125 in), B (2 235 × 2 743 mm / 88 × 108 in), M (2 438 × 3 175 mm / 96 × 125 in).
  • Prescribes a three-letter type code (e.g., AMA) used for identification and marking.
• Design requirements (Clause 4)
  • Minimum design attributes: structural enclosure, aircraft-quality materials and construction, maintainability and reparability.
  • Manufacturer obligations to provide maintenance, repair, installation and operation instructions to preserve continuing airworthiness.
• Testing (Clause 5)
  • Ultimate load tests and operational tests to verify design integrity and safe operation (these are in addition to certification load tests in ISO 21100/ISO 8097).
• Performance, loads and environment (Clauses 4–5)
  • Design loads, performance features and environmental considerations for airborne conditions.
• Markings, seals and documentation (Clauses 6–9)
  • Mandatory markings, customs/security sealing, user instructions and quality‑control/production oversight.

Applications and users

Who uses ISO 10327:2014 and why:

• Container manufacturers - design validation, production quality control, and to prepare documentation required for airworthiness approval.
• Airlines & freight forwarders - select compliant ULDs for main‑deck carriage, ensure compatibility and safe handling.
• Certification authorities & testing labs - assess operational testing and compliance in support of airworthiness approvals.
• Maintenance organizations - follow manufacturer instructions to maintain continuing airworthiness and safe serviceability.

Practical benefits include consistent container design, safer cargo restraint, clearer marking/identification, and harmonized operational testing procedures.
