Prescribes the performance test methods and requirements for elastomeric seals used in road vehicle disc brake cylinders.

This International Standard specifies the performance test methods and requirements for elastomeric seals used in road vehicle disc brake cylinders.

It is applicable to solid section type seals (square, rectangular, “O??-ring), mounted stationary in the cylinder bore or on the movable piston of disc brakes.
