The Weighing Equipment (Non-automatic Weighing Machines) Regulations (Northern Ireland) 2006

PART IV Machines 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.
