Element is accredited to perform SAE J For example, the temperature minimum and max extremes for a thermal shock test vary based on the location of the component on the vehicle.

There are further location sub-categories, but here are the basics:. Remember to consider combining humidity with hi-low temps and temperature with vibration when deciding which tests to choose. SAE sites two very relevant examples here:. Doing business with one of our laboratories enables our clients’ access to our global platform of expertise, capacity and capabilities.

Element is one of the largest independent EMC testing company’s in the world. Asking for the test data rather than a formal report will result in a cost savings.

SAE J1455 Testing Considerations

Clear inspection instructions to the test technicians are needed so they can be noted in the test data. Element can provide you with critically important data on your product or part’s performance in response to typical or extreme environmental stresses and conditions.

For each of these conditions below, SAE J gives:
