What is a Trade Approved scale?
It is a scale that has been tested and passed by the NSC as meeting their predetermined standards and level of accuracy. The NSC will issue an Approval Number, which must be displayed on each scale produced of that model. Each Trade Approved scale can only be serviced, tested and marked by an authorized scale repairer, before it can be legally used. The authorized repairer must reject (and mark accordingly) any scale that does not meet the required standards.
