Agency Approvals for Safety Standards

WirelessHART Transmitter - PDI

PDI can manage your approval process for UL, CSA, FM, CE, TUV, Atex, and much more. We have extensive experience working thru the approval and maintenance process. Acting as your agent we work directly with the assigned engineers to provide all documentation, samples, and support required for successful certification. We understand the requirements of the standards and represent our customer from a technical and administrative perspective minimizing the need to re-run tests due to failed results. Our quality department hosts required audits at our facility to fulfill the on-going listing requirements. PDI engineering staff is on hand to advise and execute report revisions as needed to maintain compliance.

Functional Test Stand Design and Construction

Product validation is a complex process; mistakes can be costly and cause delays in your schedule. PDI has extensive experience and offers product validation support for product safety and testing. We have in-house capability to design and build production test stands.

100% functional testing of a product prior to shipping is essential. PDI test engineers work closely with product designers to design and build a functional test stand to satisfy even the most demanding needs. These test stands perform a functional check for circuit operation and depending on the application have the capability to assign serial numbers, save test results in a database, and print pass/fail labels.
