InterTech Development Company has a new report, DR-132, that outlines specific challenges and solutions in automotive hydraulic testing. Critical considerations for quality control are profiled based on real-world test parameters, and issues such as safety, testing expertise and flexibility are examined.
“Hydraulic system components have a direct bearing on safety and brand reputation so they can’t go on a vehicle until they have passed strict quality control tests,” said Mr. Jacques Hoffmann, president, InterTech. “This report highlights best practices for world-class automotive hydraulic leak testing.”
According to the report, “It is essential to have a partner with technical expertise in all phases of hydraulic testing (including functional, production and audit).”
With functional testing, endurance under extreme conditions is one of the main considerations. Numerous variables are evaluated such as very hot and very cold temperatures, pressure accuracy and hysteresis so test systems must be hardy, safe and reliable. One best practice for automotive hydraulic testing is to involve engineers whose focus and background emphasize these issues.
Test stands integrated into the production line are built for speed and must have instruments that maximize throughput. Other times, parts of similar but different specifications must be audited which places different demands on testing instrumentation and operators. Those who understand the relationships of all these factors are in the best position to provide systems that complement each other in terms of performance and cost savings.
Design Report 132 from InterTech includes actual examples of test scenarios for automotive hydraulic testing in extreme conditions. The report is free and available from the InterTech web site.
