Fluid power systems. O-rings - Anti-extrusion rings (back-up rings)1 Scope This part of ISO 3601 specifies dimensions and tolerances for five types of anti extrusion rings, which are also known as back up rings: a) spiral type (T1); b) angle cut type (T2); c) solid type (T3); d) angle cut concave type (T4); e) solid concave type (T5). These anti extrusion rings are for use with selected O ring sizes as specified in ISO 3601 1 and the relevant housing dimensions specified in ISO 3601 2.

and specifies the safety related limits for each parameter as defined in EN 13848-1
