Overview
ISO 8092-4:1997 is an international standard established by the International Organization for Standardization (ISO) that specifies the dimensions and specific requirements for pins used in single- and multi-pole electrical connections in on-board wiring harnesses of road vehicles. This standard is essential for ensuring reliable and consistent electrical connectivity within automotive electrical systems, especially for connectors designed to be disconnected only for repair or maintenance after installation.
The part 4 of ISO 8092 focuses specifically on the pins of electrical connectors, detailing their dimensions and performance criteria to guarantee compatibility and durability in automotive applications. It complements other parts of the ISO 8092 series which address tabs, general requirements, and multipole connectors.
Key Topics
Applications
ISO 8092-4:1997 is particularly relevant for automotive manufacturers, electrical component designers, and maintenance professionals who require:
