PGI will be opening its newest location at a future site in Texas to give us a total of four locations to date.
What in-house testing services do you perform for quality assurance purposes?
We are committed to quality in our products, and so we conduct analysis tests from the Fuel Filler Drop Test to the U.S. Department of Transportation (DOT)-specified Drop Test. Automated multi-tank submersion leak testing is crucial to ensure 0 PPM and rule out field leaks. Additionally, we conduct other QA testing procedures for:
- Salt chamber
- Salt spray
- Paint adhesion
- Corrosion
What quality standards and requirements are you able to meet?
We adhere to all regulations per the Federal Motor Carrier Safety Administration (FMCSA), a division of DOT, including:
- Diesel tank requirements. For tanks suited to diesel fuel, DOT’s requirements are spread across three sections: Parts 393.65, 393.67, and 571.301. Under the FMCSA’s authority, these regulations cover all requirements for constructing, testing, mounting, and marking diesel fuel tanks.
- Commercial vehicle tank requirements. Part 393.67 covers more than just diesel tanks, however. It details the standards for all commercial vehicle fuel tank types, including auxiliary varieties. This regulation requires tanks and all their components to comply with set standards for construction, overfill protection, and venting in pipes, drains, fittings, joints, and more, with testing for leakage. Manufacturers must also confirm that side-mounted tanks won’t leak should they encounter impact. Diesel varieties for commercial vehicles require proper marking (i.e., the name and location of the manufacturer, the manufacture date, and a certificate verifying a tank’s compliance with FMCSA regulations).
PGI is also ISO 9001- and ITAR-certified, and we’re a trusted supplier for the U.S. military.
