Like any scientific or engineering instrument, the pendulum skid tester (also sometimes called the British pendulum or pendulum slip tester) should be calibrated at least once annually. Safety Direct America, a subsidiary of Sotter Engineering Corporation, is the leading calibrator of pendulum skid testers in the Americas.

We calibrate the pendulum using the latest British and European Standard BS EN 16165:2021, which is more recent, detailed and rigorous than the very old method in ASTM E303 and BS 7976-2:2002. The photo below shows some of the apparatus that’s used in the pendulum calibration procedure. The calibration is conducted in Mission Viejo in southern California.

We have calibrated pendulums for clients in Singapore, Canada, throughout the USA and beyond. They include forensic experts, testing laboratories, state agencies, and major tire manufacturers. The current charge is $850.00 plus shipping and new parts, if needed. Minor adjustments are included in the standard charge.
