The Automotive Filtration Laboratory at Southwest Research Institute characterizes and assesses lubricant oil, fuel and hydraulic fluid filters to determine performance and integrity according to various engineering specifications and standards. The lab provides fluid filter testing and a way to independently evaluate these specialized requirements for configurations and designs that include: spin-on, cartridge, high capacity, low or high flow, flat sheet media, fuel/water separators, single filters and dual/triple configurations.

Automotive Fuel Filter Testing & Research
Our fluid filter testing facility features versatile test systems, which can be configured to measure and acquire information essential to filter manufacture, design, development, cross-reference comparison, or qualification for a specific application. The lab utilizes devices such as particle counters (calibrated per ISO 11171) and water droplet sizers which can quantify the amount of solid contaminant or liquid upstream and downstream of a filter by means of light blockage and light scatter sensing technology.
The Automotive Filtration Lab is certified to ISO 9001 “Quality Management Systems – Requirements” and ISO 14001 “Environmental Management Systems.” The multi-pass efficiency and capacity tests we perform are also accredited to ISO/IEC 17025 “General Requirements for the Competence of Testing and Calibration Laboratories.”
