Developmental Test and Evaluation Developmental Test and Evaluation (DT&E) is normally conducted by designers of military equipment to verify that the product will meet specifications.  These tests are generally performed on the component level in a laboratory setting.  Testing is conducted early in the acquisition process.  Properly conducted, this testing can decrease the costs and

EMI emission test failures are a major cause of product development delays.  The fact is most products fail in their first trip to the lab.  Radiated Emissions is the most common problem and one that is difficult to fix.  This is true for both military and commercial products. EMI Emission Design Issues Application of ferrites

The Evolution of the Tailoring Process in MIL-STD-810 MIL-STD-810 is a standard for environmental developmental test and evaluation.  Its purpose is to provide guidance for the development of analysis and test criteria to evaluate materiel, identify deficiencies and defects, and demonstrate compliance.  The tailoring process develops valid test criteria for evaluation of materiel in MIL-STD-810.

The Importance of  Vibration Test Fixtures For most projects, the design of vibration test fixtures is often left to the last minute.  Regardless of your industry, vibration testing is one of the most important tools in product test and evaluation.  A well designed fixture will provide ample rigidity to prevent resonances that can result in

The importance of Test Witnessing is often overlooked by many engineering teams. Effective test witnessing of each individual product test or during a product test program is the best way to maximize the value returned on investment.  Testing can be expensive.  It is important to get maximum value for your company’s investment. If a product

EMI EMC Susceptibility testing is the first and most important test in any program. There have been frequent examples of product failures due to EMI EMC susceptibility issues in the news of late.  Failures like these can result in property damage, loss of life, product recall, and huge fines.  Toyota and Honda have recently had

Using Product Test Standards to Develop a Test and Evaluation Program There is a seemingly endless amount of product test standards and specifications.   These documents set criteria for compliance, provide guidance for evaluation, and sometimes assist in the development of analysis and test programs of both commercial and military products.  They are all constantly evolving as
