Y14.m are then referred to by one or more ‘datum references’ which indicate measurements that should be made with respect to the corresponding datum feature. Tolerances for the profile symbols are equal bilateral unless otherwise specified, and for the position symbol tolerances are always equal bilateral. Unequal bilateral and unilateral tolerances for profile are specified by adding further information to clearly show this is what is required.
