ASTM E 303 Skid Testing

    The ASTM E 303 skid test uses the pendulum skid tester to assess a dynamic coefficient of friction (DCOF) of roads and flooring of all types. This test method is less detailed than other pendulum test methods (such as the CTIOA, HB 198, and EN 13036-4 pendulum slip test methods), but some clients request this because it is a fairly reliable test for flooring and an official American standard. This test is also used to assess the skid resistance of road surfaces. We only need one sample to conduct this test, and it needs to be at least 5″x7″. (Larger is fine.)

    The charge for an ASTM E303 skid test is $230 per sample. Turnaround time for laboratory testing is usually 2-3 days. You can pay by credit card, Paypal, send a check with your sample, or wire transfer. We need to know the name of the client (for the purpose of the report), how you would like the sample named, and we need an email address to send the report to. Your report will be certified and stamped by a registered Professional Engineer. You can also pay for the test online by clicking the “Pay Now” button below, and then just send the info along with your samples (carefully packed) to:
