Slip Check provide calibration services at our Sydney Branch for both the pendulum friction tester specified at Appendix A of AS 4586 and AS 4663 as well as calibrations of the Dry Floor Friction Tester (FFT)
Our calibration services are the only that are accredited for both the pendulum and the FFT by the National Association of Testing Authorities (NATA) complying with AS/ISO/IEC 17025 General requirements for the competence of testing and calibration laboratories.
NATA is the authority that provides independent assurance of technical competence of industry experts. Please ensure whoever undertakes calibration of your equipment that they are NATA accredited.
Pendulum Calibration Service to BS 7976 Part 3
Slip Check can undertake calibrations of pendulum friction testers such as the Wessex slip tester and the Munro-Stanley London friction tester to BS 7976 Part 3 Pendulum Testers Method of calibration. To ensure confidence in results we recommend that the device be calibrated in line with AS/NZS 4663 and AS 4586 which specify 2 year interval between calibrations. In some circumstances this may be longer if there is adequate evidence to suggest stability in the measurements, however we recommend calibrating the pendulum friction tester on a annual basis.
On offer is also a calibration / control tile set to frequently measure and compare to ensure that the readings are consistent. If the pendulum friction tester is knocked or there is some uncertainty as to whether the accuracy has changed, a verification test on the tiles will determine whether the machine providing reliable results.
Dry Floor Friction Tester (DRY FFT) Calibration Service
Slip Check is the first organisation to be accredited by NATA to conduct calibrations of the Dry Floor Friction tester such as the Tortus MK I, Tortus MK II and Tortus MK III. We have been involved in slip testing long enough that we have experience with all three types of Tortus machines!
The challenge for a long time has been how to undertake these calibrations to verify that the machine is providing accurate results and the associated level of uncertainty. The results of dry friction measurements can quickly be placed under scrutiny and a lack of confidence in your testing may ensue if there is inadequate documentation to show that the equipment provides the right result.
Many people simply assume that because the Dry FFT is set through a “calibration” procedure onsite, this does not inherently mean that the results that the equipment reports is correct. This is where Slip Checks calibration of the Tortus and other slip testing equipment designed for Appendix B of AS 4586 and AS 4663 provides evidence of compliance.
