ISO 16750-5 Road Vehicle Compliance Testing for Electrical Equipment – Chemical Loads
ISO 16750 evaluates road vehicle electrical equipment subjected to chemical loads. As an ISO-17025 accredited environmental compliance test lab, we realize the importance of road vehicle electronic equipment testing. We understand the challenges of meeting the environmental ISO 16750-5 chemical load requirements and guide companies through the process.
Keystone has a reputation for helping customers achieve their environmental product certifications. Our engineers take a consultative approach throughout the entire test program. Lastly, we expedite comprehensive reports shortly after completion of the test.

Summary of ISO 16750-5 Chemical Load Compliance Testing
ISO 16750 applies to electrical and electronic systems/components for road vehicles. More specifically, part 5 of ISO 16750 describes potential environmental stresses for the specific mounting location on/in a road vehicle.
ISO 16750-5 describes chemical loads. The standard test method is not designed to evaluate if electronic systems or components are suitable for performing during continuous contact with an agent.
The purpose of this test is to determine whether the device under test is unacceptably affected by temporary exposure to contaminating agents.
ISO 16750-5 Road Vehicle Equipment Testing
Specific chemical agents are specified from a list within the standard. The agents are chosen depending on the mounting location of the equipment under testing.
Unless otherwise specified, only one unit per test agent is used. The units are tested with all agents they are most likely to come into contact with.
Before testing, the unit is stored at a room temperature of roughly 23 C. The relative humidity must be between 25% and 75% until the temperature and humidity are stabilized.
After conditioning, the unit is applied with the agent. This can be done one of 6 ways. Spraying, brushing, wiping, pouring, dipping, or immersing.
The device under testing is stored in a suitable chamber at room temperature and specified duration. If required, the unit is cooled down to room temperature after storage. The following program is then tested below:
- Perform a visual inspection and/or functional check.
- Condition the unit.
- Place the unit in its specified test setup. The configuration can include appropriate electrical or mechanical connections.
- Stabilize the temperature of the agent. Apply the agent to the surface of the device under testing that is likely to be exposed.
- Allow the unit to drain naturally. Shaking or wiping is not permitted.
- Maintain the temperature.
- Stabilize the unit at room temperature.
- Examine the unit immediately.
More than one cycle is allowed. If this is requested, steps 4 – 7 are repeated as desired.
