SCHEDULE 1ACCURACY CLASSIFICATION OF NON-AUTOMATIC WEIGHING MACHINES
PART IVMachines Designated Class III
14.
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.
15.
The specifications for non-graduated and graduated Class III machines are given in Table 3.
