# The Weighing Equipment (Non-automatic Weighing Machines) Regulations 1988, Paragraph 15


The specifications for non-graduated and graduated Class III machines are given in Table 3.
Table 3
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.
