SAE J should be regarded as a design guideline The specification is based upon test results from major North American truck manufacturers and component suppliers.
Humidity with both high and low temp exposure — This combination can be very important as it relates to seal integrity of electrical components under test.

SAE sites two very relevant examples here: An jj1455 test lab will also want to know this information to help determine which test equipment to utilize for the test. It will condensate at high temps, possibly penetrate seals.
SAE has identified 13 environments that will likely have an impact on components installed on a vehicle. Dae of Testing In general, SAE recommends placing the most severe environmental testing last ie. In general, SAE recommends placing the most severe environmental testing last ie.
Sample Size How many samples are necessary to draw reasonable conclusions about how the product will behave under test? This helps refine the tests to select. It is a good fit for developing a test plan for both on and off road vehicles as well as heavy duty trucks.
Temperature cycling is m1455 performed first to condition the test article to function mechanically. At low temps, water can freeze inside the component if the seal has failed.

The specification is based upon test results sze major North American truck manufacturers and component suppliers. In addition to vibration i1455, Element provides a range of dynamics testing including acceleration, shock, drop, structural, fatigue and rotating load simulations. The tests called out in SAE J should not replace actual operating specifications.

SAE J contains a table outlining those temperature extremes. Know that ultimately j14555 test will be a short duration of environmental exposure. Temperature and vibration — will the products design and mounting location be susceptible to the simultaneous combined exposure of both temp and vibration? J145 can help advise on how long the individual test profiles in SAE J take and will work with you to determine the most efficient and cost effective scheduling possible.
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:
