Reduce the size of load receptor

Trading Standards permit the physical dimension of the load receptor to be reduced from that specified on the Certificate of Approval providing that the dimensional sizes of the members making up the framework are not altered from the original Certificate of Approval.

Increase the verification scale interval value

The verification scale interval value can be increased as long as the following criteria are met:

  • the scale interval value is based on the 1, 2, 5 principle (as per Regulation 48(1)(f) of the Regulations)
  • where the scale interval value is increased, the new number of divisions ‘n’ must not cause the instrument to have changed the instruments accuracy class
  • No increase to the maximum capacity.
