ISO/TC 22/SC 32/WG 7 - Functional characteristics of starting devices and electrical generators

This document defines the durability test methods of a starter relay for passenger vehicles (12 V) with a stop and start system. It uses a simulated electrical load to represent the starter solenoid.

This document defines requirements and recommendations for starter motor durability testing of 12 V start systems for internal combustion engines. This includes test methods, test procedures and capabilities of test benches.

ISO 8856:2014 lays down test methods and general requirements for the determination of the electrical characteristics of DC starter motors intended to start internal combustion engines of road vehicles.

ISO 8854:2012 specifies test methods and general requirements for the determination of the electrical characteristic data of alternators for road vehicles. It applies to alternators, cooled according to the supplier's instructions, mounted on internal combustion engines.
