The CADEX test protocol consists of two tests:

HIGH PRESSURE TOLERANCE TEST: First, the tire is inflated to 72.5 psi (5 bar), an average minimum pressure for most riders on 25c tires, and must withstand this pressure for 24 hours without blowing off. Next, the tire is inflated to its recommended maximum pressure and must withstand this pressure for 24 hours without blowing off. After that, the tire is inflated to 1.2 times the recommended maximum pressure and must withstand this pressure for 24 hours without blowing off. Finally, the tire is inflated to 1.5 times the recommended maximum pressure and must withstand this pressure for 24 hours without blowing off. The final number of 1.5 times the recommended maximum pressure is intended to simulate such extreme conditions as hitting a square edge or a pothole at high speed causing the tire pressure to increase suddenly. If the tire has been able to withstand the four pressures for 24 hours respectively without blowing off, it passes the CADEX high pressure tolerance test. For your own safety, please do not inflate the tire over the recommended maximum pressure or attempt to replicate this test.

HIGH PRESSURE BRAKING TEST: The tire is inflated to 1.2 times the recommended maximum pressure, mounted on a disc brake wheel and must withstand braking forces without blowing off or experiencing a shift in position of more than 3mm. This test is used to simulate accidental high-speed uncontrolled braking causing excessive friction between road and tire and possible movement of the tire on the rim resulting in blow-off. For your own safety, please do not inflate the tire over the recommended maximum pressure or attempt to replicate this test.
