The Weighing Equipment (Non-automatic Weighing Machines) Regulations 1988

PART V MACHINES DESIGNATED CLASS IIII

16.  A machine which is—

(a) made in accordance with an approved pattern and marked

in accordance with the published particulars of that pattern, or

(b) first stamped before 1st November 1988 in accordance with the provisions for crane weighing machines constructed upon the hydraulic principle in the Weights and Measures Regulations 1963, or

(c) of the type referred to as “approximate weighers” and first stamped before 1st November 1988,

is a Class IIII machine.

17.  The specifications for non-graduated and graduated Class IIII machines are given in Table 4.

Table 4

Maximum capacity “Max”	Lower limit of the minimum load “Min”	Scale interval “d”	Number of scale intervals “n”	Verification scale interval “e”
Notes 1. In the case of machines where the weight indicating or printing is in units of the imperial system the relevant capacity and verification scale interval shall be the amounts in imperial units which are equivalent to those specified in the Table in terms of g, kg and t. 2. Where the equivalent metric value for an imperial scale interval falls between ranges then the value shall be considered as belonging to the lower range.
