Workhorse Custom Chassis achieved official ISO 9001 certification Sept 23, 2000. Certification covers the design, sale, and assembly of recreational vehicle and commercial truck chassis and commercial trucks.
This certification follows an August 2000 audit of Workhorse quality systems conducted by NSF-ISR, a registrar for companies worldwide. Procedures inspected by this independent audit were developed and instituted by the Workhorse ISO Core Team starting in February 1999, the same month the company began producing its first chassis.
