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 1988 and marked “Class C” in accordance with the provisions for beam scales in the Weights and Measures Regulations 1963, or
(c)of a type referred to as “common form” and which was first stamped before 4th April 1989
is a Class III machine.
15. The specifications for non-graduated and graduated Class III machines are given in Table 3.
