Aircraft ground support equipment - Specific requirements - Part 18: Nitrogen or Oxygen units

This document specifies the technical requirements to minimise the hazards listed in Clause 4 which can arise during the commissioning, operation and maintenance of nitrogen or oxygen units when carried out in accordance with the specifications given by the manufacturer or his authorised representative. It also takes into account some performance requirements recognised as essential by authorities, aircraft and ground support equipment (GSE), manufacturers as well as airlines and handling agencies.
This document applies to:
-   all types of mobile nitrogen units and oxygen units with transportable gas cylinders interchangeable for filling purposes;
-   equipment to be carried with other GSE or vehicles, e.g. skid mounted units,
intended for the manual refill of gaseous nitrogen or oxygen on aircraft (Examples see Annex A).
NOTE   Generally oxygen units are used under aircraft maintenance conditions, not under commercial servicing conditions.
This document does not establish requirements for noise and vibration.
Noise and vibration are dealt with respectively in EN 1915 4 and EN 1915 3.
This document does not deal with hazards in respect to a standard automotive chassis and from other vehicles on the apron.
This Part of EN 12312 is not applicable to nitrogen or oxygen units which are manufactured before the date of publication of this document by CEN.
This part of EN 12312 is intended to be used in conjunction with EN 1915-1, EN 1915-2, EN 1915-3 (for vehicles) and EN 1915-4.

Dieses Dokument legt die technischen Anforderungen zur Minimierung der in Abschnitt 4 aufgelisteten
Gefährdungen fest, die bei der Inbetriebnahme, Betrieb und Wartung von Stickstoffgeräten oder Sauerstoffgeräten
auftreten können, wenn diese in Übereinstimmung mit den Anweisungen des Herstellers oder seines
Beauftragten ausgeführt werden. Es berücksichtigt auch einige Funktions- und Gestaltungsanforderungen, die
von offiziellen Stellen, Luftfahrzeug- und Bodengeräteherstellern sowie Luftverkehrs- und Abfertigungsgesellschaften
als wesentlich erachtet wurden.
Dieses Dokument gilt für:
- alle Bauarten von mobilen Stickstoffgeräten und Sauerstoffgeräten mit transportablen Gasflaschen, die
zum Füllen ausgetauscht werden können;
- Geräte zum Mitführen auf anderen Bodengeräten oder Fahrzeugen, z. B. auf Kufen montierte Einheiten,
die für das manuelle Nachfüllen von gasförmigem Stickstoff oder Sauerstoff an Luftfahrzeugen bestimmt sind
(Beispiele siehe Anhang A).
ANMERKUNG Sauerstoffgeräte werden in der Regel bei der Wartung von Luftfahrzeugen eingesetzt, nicht im allgemeinen
Luftverkehrsbetrieb.
Dieses Dokument enthält keine Festlegungen hinsichtlich Lärm und Schwingungen.
Lärm und Schwingungen werden in EN 1915-4 bzw. EN 1915-3 behandelt.
Dieses Dokument behandelt keine Gefährdungen, die von einem Serienfahrgestell und von anderen Fahrzeugen
auf dem Vorfeld ausgehen.
Dieser Teil von EN 12312 gilt nicht für Stickstoffgeräte oder Sauerstoffgeräte, die hergestellt wurden, bevor
dieses Dokument durch CEN veröffentlicht wurde.
!Es ist beabsichtigt, diesen Teil der EN 12312 in Verbindung mit EN 1915-1, EN 1915-2, EN 1915-3 (für
Fahrzeuge) und EN 1915-4 anzuwenden."

Overview

EN 12312-18:2005+A1:2009 is the CEN Type C standard that defines specific safety, functional and performance requirements for mobile nitrogen and oxygen units used as aircraft ground support equipment (GSE). It covers design, commissioning, operation and maintenance measures to minimise hazards associated with transportable gas cylinders and pressure filling systems when used according to the manufacturer's instructions. The Part 18 standard applies to mobile, towable, pedestrian-controlled and skid‑mounted units with interchangeable cylinders and is intended to be used together with the EN 1915 suite.

Key topics and technical requirements

• Scope & applicability
  • Applies to all mobile nitrogen and oxygen units with transportable cylinders; not applicable to units manufactured before publication.
  • Note: Oxygen units are generally for maintenance use rather than in‑service commercial servicing.
• Gas system requirements
  • Units must be designed for one gas type only (nitrogen or oxygen).
  • Pressure vessels/cylinders to meet EN 1964-1; cylinder valves to EN 849.
  • Pressure filling systems require a low-pressure gauge (accuracy class 1) per EN 837-1.
  • Pipes, fittings and pneumatic components to meet EN 983 where applicable.
• Mechanical & safety design
  • Stability and strength per EN 1915-2; electrical systems for battery-powered units per EN 1175-1.
  • Seating restraint: self‑propelled units require at least lap‑type seat belts.
  • Towable units must be towable up to 32 km/h (20 mph) (negotiable with buyer).
  • Hoses must be suitable for the gas, adequate length, and have protected stowage to prevent kinking.
• Oxygen‑specific controls
  • Materials in contact with oxygen must be oxygen‑compatible (examples: copper, copper‑nickel alloys).
  • Units must provide space for at least one 6 kg fire extinguisher and designs must avoid oxygen accumulation.
  • Prominent safety markings and specific operating warnings (e.g., “Oxygen! Do not use oil or grease!”).
• Marking & documentation
  • Permanent data plates and clear gas‑type marking (letters ≥100 mm high).
  • Comprehensive operating and maintenance instructions, operator training guidance and emergency measures.

Applications and users

• Who uses this standard
  • GSE manufacturers, aircraft and component OEMs, airlines, ground handling agencies, airport safety engineers, maintenance workshops, procurement teams and regulatory bodies.
• Practical uses
  • Design specification and compliance for new nitrogen/oxygen units.
  • Procurement criteria and acceptance testing of GSE.
  • Operator training, safe operating procedures and maintenance planning.
  • Risk assessment and verification activities during certification or in‑service audits.
