Paragraph 13 I1

England, Wales and Scotland

The specifications for non-graduated and graduated Class II machines are given in Table 2.

Table 2

Maximum capacity “Max”	Lower limit of the minimum load “Min”	Scale interval “d”	Number of scale intervals “n”	Verification scale interval “e”
Notes 1. When a machine is provided with a rider its verification scale interval shall be the smaller of the following— (a) the verification scale interval of the machine not taking into account the rider, or (b) the scale interval of the rider device. 2. When graduated self or semi-self indicating machines are provided with a device for interpolation of reading, this shall not be taken into account when determining the verification scale interval of the machine. 3. When graduated self or semi-self indicating machines are provided with an indicating device on which the last figure is clearly differentiated from the other figures, the verification scale interval shall correspond to the last but one figure of the indication. 4. Machines of a maximum capacity equal to or greater than 1 kg of an actual scale interval of 100 mg and of a verification scale interval of 1 g may belong to this class of machine, provided that the last figure is clearly differentiated from the other figures. 5. In the case of machines where the weight indicating or printing is in carat (metric) units or ounces troy the relevant capacity and verification scale interval shall be the amounts in carat (metric) or ounces troy respectively which are equivalent to those specified in the Table in terms of mg, g and kg. 6. Where the equivalent metric value for an ounce troy scale interval falls between ranges then the value shall be considered as belonging to the lower range.
