AIA/NAS Aerospace Standards

This standard is applicable to manual soldering and machine soldering processes utilizing controlled soldering devices, for electrical connections for wiring and cabling used in aerospace vehicles. Description of a component or device herein is not to be construed as authorizing the use of the component or device.

Safety Considerations

This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of users of this standard to comply with appropriate safety and health practices and regulatory limitations.

Strain Relief

The use of solder devices for wire or cable terminations in aircraft requires strain relief in all applications or designs with no strain on the solder terminations. Soldered wire or cable terminations may separate under physical load. The separation time is function of the ambient and electrical temperatures.

Solder Joint Protection

Sealing protection for solder terminations is recommended when a potential electrical overload could cause the solder to melt and short adjacent terminations.
