Overview

IEC 63067:2020 is an international standard developed by the International Electrotechnical Commission (IEC) that establishes general requirements and testing procedures for connecting devices used in electrical installations for lighting and beaconing at aerodromes. Specifically, this standard applies to plugs and receptacles for single or multiple-pole connecting devices tailored for aeronautical ground lighting applications. It ensures the reliability, safety, and interoperability of these devices in harsh environmental conditions typically found in aerodrome operations.

The standard aligns with environmental class E11 as defined in IEC 61820-1, which covers environmental and operational performance. IEC 63067:2020 also references the broader IEC 61820 series for additional requirements related to the use and specification of connecting devices in this field.

Key Topics

• Scope and Applicability
  IEC 63067 addresses single and multiple pole plugs and receptacles used for aerodrome lighting and beaconing installations, focusing on electrical and mechanical performance to assure operational safety.

• General Requirements
  The standard specifies general construction, marking, and documentation requirements to ensure device traceability, compatibility, and user safety.

• Testing Procedures
  Comprehensive tests include insulation resistance, electrical connection integrity, mechanical durability, water ingress protection, and resistance to weathering, corrosion, and UV radiation. These tests guarantee dependable performance in environmental class E11 conditions, which include exposure to moisture, temperature variations, and dust.

• Ratings and Classification
  Devices are classified according to voltage rating, current rating, and environmental protection level. This classification helps in selecting appropriate connecting devices for specific aerodrome lighting applications.

• Protection and Safety
  IEC 63067 covers electrical protection against shock, continuity provisions for screened cables, and dimension checking to ensure connectors fit and function safely.

• Construction Details
  Detailed requirements for housing, pins and sockets, caps, and assemblies ensure robust mechanical design capable of withstanding field conditions.

• Cabling and Terminations
  The standard defines acceptable methods for conductor termination, including crimped connections consistent with IEC 60352-2, ensuring secure electrical and mechanical connectivity.

Applications

IEC 63067:2020 connecting devices are essential components in aerodrome ground lighting systems, which include runway lights, taxiway lights, and beaconing systems critical for aircraft guidance. Typical applications include:

• Aeronautical Ground Lighting Installations
  Providing secure and reliable electrical connections for low-voltage lighting circuits in airports and heliports.

• Beaconing Systems
  Ensuring continuity and protection of cables and connectors powering airport beacons used to signal aircraft position and status.

• Maintenance and Field Operations
  Designed for ease of installation and replacement under field conditions. The devices satisfy environmental and mechanical stresses encountered during maintenance activities in airports.

• Compliance and Safety Assurance
  Meeting international standards like IEC 63067 supports compliance with regulatory aviation and electrical safety requirements, thus promoting interoperability across global aerodrome infrastructures.

Related Standards

• IEC 61820 Series
  Provides additional requirements and usage guidelines for electrical installations in aeronautical ground lighting. It complements IEC 63067 by covering fundamental principles, construction, and operational aspects.

• IEC 60352-2
  Addresses solderless crimped connections, a key terminations method referenced by IEC 63067, ensuring reliable cable-to-connector interfaces.

• IEC 60529 (IP Code)
  Specifies degrees of protection provided by enclosures against solids and liquids, relevant for connector ingress protection classification.

• ISO 2859-1
  Defines sampling procedures for inspection by attributes, used for production test plans ensuring consistent quality compliance.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC
Publication(s)"). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
