Summary of the ISO 16750-1 General Requirements

The objective of ISO 16750 is to assist users in defining and applying internationally accepted environmental conditions, tests, operating requirements, etc. ISO 16750-1 presents definitions and specifications for the potential environmental stresses than can affect equipment. More specifically, the standard evaluates electrical and electronic equipment in respect of their mounting location directly on or in a road vehicle.

This test method does not cover electromagnetic compatibility (EMC) testing.

It is recognized that units with several mounting locations are tested to meet the most severe requirements.

Unless otherwise specified, all tests are performed at a room temperature of 23 C and relative humidity of 25% to 75%. Before testing, a test sequence is agreed upon. This includes stating the type, number, combination, and sequence of individual tests.

Scope of ISO 16750 Regulatory Compliance Testing

Mounting Location

The standard classifies equipment by mounting location:

Engine Compartment

The unit under testing is mounted

To the body
To the frame
On/in the flexible plenum chamber
On/in the engine
On/in the transmission/retarder

Passenger Compartment

The unit is mounted in a position

Without special requirements
Exposed to direct solar radiation
Exposed to radiated heat (other than solar radiation)

Luggage compartment/load compartment

The unit is mounted

Inside

Mounting on the exterior/in cavities

The unit is mounted

To the body
To the frame
On the underbody/in the wheel housing
- Sprung masses
- Unsprung masses
In/on a passenger compartment door
To the engine compartment cover
To the luggage compartment cover

Operating Modes

The test has 3 operating modes that apply.

Operating mode 1 – No voltage is applied to the unit under testing.

Operating mode 2 – The unit under testing is electrically operated with supply voltage.

Operating mode 3 – The unit is electrically operated with supply voltage.
