10 Identification statement (reference to this
   part of ISO 3601)

Describes dimensions and tolerances for five types of anti-extrusion rings, which are also known as back-up rings: 1. spiral type (T1); 2. angle cut type (T2); 3. solid type (T3); 4. angle cut concave type (T4); 5. solid concave type (T5).

This part of ISO3601 specifies dimensions and tolerances for five types of anti-extrusion rings, which are also known as back-up rings: spiral type (T1); angle cut type (T2); solid type (T3); angle cut concave type (T4); solid concave type (T5). These anti-extrusion rings are for use with selected O-ring sizes as specified in ISO3601-1 and the relevant housing dimensions specified in ISO3601-2.
