Test Witness
Independent Third-Party Evaluation


Having your tests conducted correctly is important, and that usually means having a company representative be the test witness at the test lab.  An option to the expense of sending a company engineer to a test lab is to use a reliable third-party technician from CVG Strategy. This can be especially important when travel of important development team members is not prudent.

Our technical personnel are trained on the standards and have conducted many hundreds of tests themselves, on behalf of clients.  We are available for climatic, dynamic, EMI/EMC testing and have expertise in a wide variety of defense and commercial standards.

We can also generate required documentation for defense test and evaluation.  We have test plan templates available or we can create a custom test plan for you specific requirements.
