PART IVMachines Designated Class III
I114
A machine which is—
a
made in accordance with an approved pattern and which is or could be marked
, or
b
first stamped before 1st November 1991 and marked “Class C” in accordance with the provisions for beam scales in the Weights and Measures Regulations (Northern Ireland) 1967, or
c
of a type referred to as “common form” and which was first stamped before 1st August 1991,
is a Class III machine.
I215
The specifications for non-graduated and graduated Class III machines are given in Table 3.
