Requirements for use for trade
No person shall use for trade a beltweigher unless—
(a) it is compliant with the essential requirements other than the provisions relating to maximum permissible errors;
(b) the requirements of paragraphs 35 and 36 are complied with;
(c) it has been erected and installed in accordance with the requirements of paragraph 37; and
(d) in the case of a beltweigher which is stated to be of an accuracy class set out in column 1 of the Table set out in this paragraph it is within the maximum permissible error for that accuracy class as set out in column 2 of that Table.
Manner of use
(1) Where a beltweigher is marked with a temperature range, it must not be used for trade in temperatures outside that range.
(2) Where a beltweigher bears a mark which signifies the manner and purpose of use, it must not be used for trade in a manner or for a purpose which does not accord with that marking.
(3) A beltweigher of accuracy class 2 must only be used for trade for weighing any of the materials to which the term “ballast” applies in Schedule 4 of the 1985 Act.
(4) A beltweigher must not be used for trade in such a manner as to cause—
(a) spillage of material from the belt; or
(b) loading of the weighing unit above its maximum capacity.
(5) A beltweigher must not be used for trade in circumstances—
(a) in which it may be prevented from operating consistently or accurately; or
(b) in which are likely prematurely to degrade its metrological characteristics.
Position of the operator
Every beltweigher must be erected in such a manner that the operator can readily take up a position from which he can—
(a) read any indication of zero totalisation;
(b) operate any zero-setting control; and
(c) see whether the belt passing over the weighing unit is empty.
Manner of erection and installation
(1) Every beltweigher must be positioned so as to facilitate cleaning and testing.
(2) The installation of a beltweigher must be so designed that an automatic weighing operation will be the same for testing as for a transaction.
(3) Every beltweigher must be erected in such a way that it is possible to carry out a material test in a place where it is to be used, including in particular the depositing on, or removal from, the belt of material test loads in a reliable and easy manner, without disrupting the normal operation of the beltweigher.
(4) Any special equipment for the control of the measuring tasks of a beltweigher which is not a permanent fixture of the beltweigher, must be kept in the vicinity of the beltweigher.
