The FAA L-823 standard published by the Federal Aviation Administration (FAA) defines requirements for primary connector kits. Primary connector kits are used to make serviceable waterproof splice connections of single conductor airport lighting cable. It is also used to connect the primary wire to the isolation transformer during installation.

This specification contains requirements for plugs and sockets (cable connectors) used for underground cable connections, power cables, isolation transformer terminals, and lighting fixture terminals in airport systems.
Cable connectors are classified according to this specification as:
Plugs and sockets covered by this specification are:
Plugs and sockets covered by this specification have the following connection methods:
In addition, the housing styles of plugs and sockets covered by this specification are defined.
All plugs and sockets (cable connectors) must be manufactured according to the specification requirements described.
In terms of environmental requirements, plugs and sockets (cable connectors) should be designed for continuous use in the temperature range of minus 55 degrees to plus 65 degrees, when exposed to air, submerged in water or buried in the ground.
Performance requirements are covered in the specification under the following headings: electrical connection, bond strength, mechanical bonding and sealing.
The specification covers the requirements for fabrication and materials under the headings: general, housing, pins and sockets, connector assemblies, marking, covers, and assembly instruction.
To demonstrate compliance with all specifications, the following tests are performed on each unit submitted for qualification: dielectric tests (plugs and sockets, connector assembly), bond test, mechanical connection test, electrical connection test, weathering test and metal bond test.
In addition, production tests are carried out and each connector is visually inspected and interface dimensions are checked according to certain process control. Each plug and socket (cable connector) is subjected to a dielectric and continuity test.
Among the numerous tests, measurements, analyses, and evaluations our organization provides for businesses in various sectors, we also offer testing services for primary connector kits under the FAA L-823 standard, utilizing a trained and expert staff and advanced technological equipment.
