regulation 5(b)
An automatic rail-weighbridge with an accuracy class of 2 shall only be used for the weighing of a wagon loaded with waste; for the purposes of this provision, “waste” shall be construed in accordance with section 75 of the Environmental Protection Act 1990 M1, provided that “waste” shall include any waste disposed of for reprocessing or recycling purposes but shall not include any radioactive waste as defined in [F1paragraph 5 of schedule 8 of the Environmental Authorisations (Scotland) Regulations 2018] [F2Schedule 23 to [F3the Environmental Permitting (England and Wales) Regulations 2016]];

Single axle or bogie weights shall not be indicated or printed without an associated warning that these weighing results cannot be verified.
Automatic rail-weighbridges shall comply with the appropriate metrological and technical requirements at temperatures from 10 °C to +40 °C.
For special applications, however, the limits of the temperature range may differ provided that this range shall not be less than 30 °C and shall be specified in the descriptive markings as set out in Schedule 4.
Where an automatic rail-weighbridge is marked with a temperature range, it shall not be used for trade in temperatures outside that range.
If the scale interval for stationary load is not equal to the scale interval (d), it shall be automatically out of service when the automatic rail-weighbridge is in use for weighing-in-motion. In addition, if the weighbridge is not verified for use as a non-automatic weighing instrument, the scale interval for stationary load shall not be readily accessible and shall only be used for static testing.
Automatic rail-weighbridges shall be designed to suit the vehicles, site and method of operation for which they are intended.
Weighbridges constructed only for partial weighing shall not be used to weigh liquid loads or any other load that may be subjected to fluctuations in its gravity centre, unless there is a possibility to anticipate and compensate for such fluctuations.
3.3.2. Interlocks shall prevent the use of any control device that may alter a weighing operation.E+W+S
3.3.3. Automatic rail-weighbridges used for uncoupled wagon weighing shall recognise and indicate the following situations:E+W+S
(a)the passage of two or more coupled wagons;
(b)the passage of two or more uncoupled wagons that is sufficiently close to cause either a malfunction of the instrument or errors exceeding the appropriate maximum permissible errors.
3.4.1. The weight indication shall be the self-indicating type. Indicating and printing devices shall allow reliable, simple and unambiguous reading of the results by simple juxtaposition and shall bear the name or symbol of the appropriate unit of mass.E+W+S
3.4.2. The minimum printout resulting from each normal weighing operation shall be each wagon weight in the case of wagon weighing and total train weight in the case of train weighing.E+W+S
3.4.4. The printer shall not print the weight of any wagon that has travelled over the load receptor at a speed outside the range of operating speeds. An appropriate indication shall be included on the printout for any wagon weight not printed and a subtotal may be printed exclusive of unweighed wagons provided that an indication clearly specifies that it is not the total train weight.E+W+S
3.4.5. The weight indication and printout shall not be altered due to any part of any wagon travelling over the load receptor more than once.E+W+S
Upon switch-on (in the case of electronic automatic rail-weighbridges permanently connected to the mains at switch-on of indication), a special procedure shall be performed that indicates all the relevant signs of the indicator in their active and non-active states for a sufficient time to be easily observed by the operator.
An automatic rail-weighbridge shall only be used for trade for the purpose of weighing material the values of which, expressed in units of measurement of mass, are within the weight range specified in the certificate of approval relating to that weighbridge.
The minimum capacity shall not be less than 1t, and not greater than the value of the result of the minimum wagon weight divided by the number of partial weighings.
The minimum wagon weight shall not be less than 50d.
