We hold ourselves to the highest standards, regularly participating in ASTM Proficiency Testing to ensure our data is accurate every single time. We are proud to be a leading lab in the industry and offer a variety of ISO, ASTM, and API standardized tests. We also specialize in customized testing solutions and will build a test plan designed to suit your needs.

Our experience in engineering adds value to our testing services in a unique way not found at other labs. We are educators at heart which means you will always get more than just data. We will also take the next step and provide an analysis of what your data means to your product, application, and performance. When you test with PSN, you have a team of experts working for you.
