This part of IS0 228 specifies the verification, by means of limit
gauges, of cylindrical threads, the dimensions and tolerances
of which are given in IS0 228-l.
For industrial applications (see for example IS0 1179), it may be
necessary to carry out additional checks.
Since this 55O profile has different elements to be verified, it is
necessary to provide for several GO and several NOT GO
gauges :
a) the threaded GO gauges (see clauses 6 and 7) shall ensure
that the profile of the machined piece does not exceed
the maximum of material provided for by the tolerances applied
to the dimensions of the profile defined by IS0 228-l;
b) the threaded NOT GO gauges for the threads of the
pieces (see clauses 6 and 7) fix the minimum material limit
on the flanks of the thread.
NOTE - Reference checks may be carried out in specialized laboratories.
