Waekon FPT26-21 - Pass/Fail Standard for Cal Check

The Pass Fail Standard for Cal Check is designed for daily calibration verification under Inspection and Maintenance (I/M) protocols. This standard ensures that caps meet strict leak criteria, critical for accurate emissions testing. While a failing cap will not trigger the Check Engine light, it can still cause a vehicle to fail emissions due to leaks exceeding 0.004 inches (equivalent to 60cc per minute at 30" H2O pressure). Using this standard helps technicians identify non-compliant caps during routine checks, maintaining regulatory compliance and ensuring reliable calibration performance in emissions control systems.
