Quality Assurance and Certifications

Petro-Lubricant Testing Laboratories is an ISO 9001:2015 and ISO 17025-2017 accredited testing laboratory. You can be assured that the data we generate is of the highest quality.  We hold our employees accountable for the integrity of their data and ensure that they are free from improper or undue influence regarding the generation, handling and reporting of data.  We review this policy annually with our employees.

We are committed to maintaining a quality system and we work to continuously improve our data quality and customer service. We utilize both internal and external assessments to routinely evaluate and verify our Quality Assurance System. As part of our Quality Program, our ISO accreditation is assessed annually by Perry Johnson Registrars and we have achieved and maintain “Preferred Laboratory” status with many of our clients.

Our Quality Program ensures that we are testing to current ASTM test methods and military specifications. We review our test methods annually with assessments to validate performance of the test methods and to re-qualify our technicians to perform these methods. We maintain a formal training program to ensure that only qualified, competent personnel perform laboratory activities. Our data quality is continuously monitored by participation in Inter-laboratory Crosscheck programs and with statistical quality control.

Customer service is also very important to us and is continuously monitored for improvements utilizing our Service Performance Survey and any personal communications we receive. You can contact the Quality Assurance Manager at
