Automotive Industry Testing

ATRONA Material Testing Labs has been involved with
automotive testing for close to a decade. We have
assisted customers with all types of static and dynamic
testing related to seats, recliners, doors, and trunks;
either individual tests or full engineering specification
testing with full formal reports presented per standards.
The following is a list of some of the tests that we have
performed here at the lab. We also performed custom
testing designed by ATRONA and approved by the
customer.
