Definitions

2. In these Regulations, unless the context otherwise requires —

“automatic weighing machine” means a machine in which special self-acting machinery is introduced to effect an automatic feed, the rapid weighing of given loads, the registration and summation of loads and other similar purposes or some of them;

“beam scale” means any equal-armed weighing instrument, the pans of which are below the beam;

“capacity”, in relation to a weighing instrument, means the maximum load which the equipment is constructed to weigh;

“counter machine” means any equal-armed weighing instrument of a capacity not exceeding 50 kilograms, the pans of which are above the beam, and includes, together with the ordinary type, such instruments as are specially designed for counter use, and which do not exceed the said capacity;

“crane weighing machine” means a weighing instrument designed on a lever or spring principle specially constructed to enable suspension from the hook of a crane and fitted with a hook for lifting any load;

“daching” means an unequal armed balance of a capacity not exceeding 200 kilograms;

“dead weight machine” means any weighing instrument similar in principle of construction to a counter machine but of a capacity of 50 kilograms or more, and includes such an instrument —

(a)	with the weighing platform near to the ground and with the connecting stays or hooks above the beam and commonly known as a low pattern machine or cotton machine;
(b)	with the weighing platform at any convenient height and with the connecting stays or hooks below the beam, and commonly known as a high pattern machine or single machine; and
(c)	which combines the characteristics of the instrument in paragraphs (a) and (b), and commonly known as a double machine;

“error” is the least weight which when added to or removed from a weighing instrument will bring the indicator to the position of poise or equilibrium from a position of imbalance;

“licence” means a licence issued under these Regulations;

“licensee” means any person to whom a licence is issued under these Regulations;

“measuring instrument” means any measuring equipment other than a capacity measure;

“person weighing machine” means any weighing instrument of a type specially designed for weighing persons, and for the use of which a charge is made;

“platform weighing machine” means a weighing instrument with compound levers and with the goods receptable generally in the form of a platform. The capacity of this machine shall not exceed 3 tonnes and the weight of the load shall be indicated with a steelyard or other form of indicator;

“sensitiveness” is the least weight which when added to or removed from the loading platform or pan when the machine is in equilibrium will cause an appreciable movement of the indicator from its position of equilibrium;

“spring balance” means any weighing instrument in which weight indications are dependent on the extension of a spring, and which is so constructed that the load, whether above or below the spring is suspended directly from it;

“steelyard” means an unequal armed balance of a capacity exceeding 15 kilograms;

“weighbridge” means a weighing instrument constructed with compound levers, with the indicator system carried on foundations separate from the lever systems for weighing loads of 1,000 kilograms and over, through the medium of proportional weights or indicating mechanism;

“weighing instrument” means any weighing equipment other than a weight or counterpoise;

“weight increment”, in relation to a self-indicating person weighing machine, means the weight equal to the difference between the weights represented by consecutive graduation lines, and, in relation to a device for indicating the weight on a ticket or for announcing the weight, means the weight equal to the difference between any two consecutive weights which the machine is capable of indicating or of announcing, as the case may be.
