(second part)	1 e	2 e	more than 50 000 e and not more than 200 000 e
(third part)	1.5 e	3 e	more than 200 000 e
Class II

(second part)	1 e	2 e	more than 50 e and not more than 200 e
(third part)	1.5 e	3 e	more than 200 e

2.  An indicating or printing device which, in any single weighing mode, has more than one verification scale interval, each of which relates exclusively to a particular part of the weighing range, shall have, for each particular part, those error allowances which would apply if the complete weighing range had the verification scale interval which relates to that particular part.

3.  In the case where—

(a) a machine has had its stamp obliterated under regulation 43(2) of these Regulations because of an alteration or adjustment involving only the replacement or addition of a dial, chart or pointer, and

(b) the purpose of the alteration or adjustment was to modify an imperial machine to indicate weight in metric units, and

(c) (i) within the period of fifteen days following the making of the alteration or adjustment the requirements of paragraph 4 below were complied with, or

(ii) the period for complying with those requirements has not yet expired,

the appropriate prescribed limits of error upon the first retesting of such a machine with a view to its being passed as fit for use for trade shall be those set out in the Table in paragraph 1 above as being applicable in relation to the obliteration of stamps.

4.  The requirements referred to in paragraph 3(c)(i) above are that the chief inspector of weights and measures for the area in which the machine will first be used for trade after it has been altered or adjusted, or if the address at which it will be so used is not known, for the area in which the alteration or adjustment is carried out, is furnished by the person carrying out the alteration or adjustment with the following particulars, namely—

(a) his name and address;

(b) particulars by which the machine may be identified;

(c) the name and address of the person who will first use the machine for trade after its alteration or adjustment and the address at which it will be so used or, if those particulars are not known, an address at which the machine will be available for inspection;

(d) confirmation that the modification consisted only of the replacement or addition of a chart, dial or pointer.
