SAE J Testing | Element
SAE has identified 13 environments that will likely have an impact on components installed on a vehicle. For example, the temperature minimum and max extremes for a thermal shock test vary based on j14555 location of the component on the vehicle. How many samples are necessary to draw reasonable conclusions about how the product will behave under test? What is the cost of SAE J testing?
It is a good fit for developing a test plan for both on and off road vehicles as well as heavy duty trucks. 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.
There are further location sub-categories, but here are the basics:. SAE sites two very relevant examples here:.
SAE J contains a table outlining those temperature extremes. The tests called out in SAE J should not replace actual operating specifications.
An independent test lab will also want to know this information to help determine which test equipment to utilize for the test. Number of cycles Know that ultimately the test will be a short duration of environmental exposure.
Make an inquiry today. Temperature and vibration — will the products design and mounting location be susceptible to the simultaneous combined exposure of both temp and vibration? For each of these conditions below, SAE J gives: Remember to consider combining humidity with hi-low temps and temperature with vibration when deciding which tests to i1455.
This should be determined before testing begins. In addition to vibration testing, Element provides a range of dynamics testing including acceleration, shock, drop, structural, fatigue and rotating load simulations. There are further location sub-categories, but here are the basics: Temperature cycling is often performed first to condition the test article to function mechanically.
That is a different test all together. View more articles about Transportation More Sectors Find related articles to you through the Nucleus. It will condensate at high temps, possibly penetrate seals.
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.
Element 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. Sequence of Testing In general, SAE recommends placing the most severe environmental testing last ie.
SAE J1455 Testing Considerations
Clear inspection instructions to the test technicians are needed so they can be noted in the test data. View more articles about Transportation More Sectors. Humidity with both high and low temp exposure — This combination can be very important j14555 it relates to seal integrity of electrical components under test.
The specification j14555 based upon test results from major North American truck manufacturers and component suppliers. 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.
