These organisations ensure that all scales used in commercial and healthcare applications meet the necessary standards.
SANAS and NRCS Guidelines
SANAS is responsible for accrediting organisations that verify the accuracy of measuring instruments, including weighing scales. For businesses to legally use weighing scales, they must ensure their scales are calibrated and meet the required standards. NRCS, on the other hand, enforces compulsory specifications for certain types of measuring instruments, including those used for trade purposes.
Regulatory Requirements for Weighing Scales:
- Weighing scales must conform to the Legal Metrology Act, which governs the use of measurement instruments in trade to protect consumers.
- Scales used in trade must comply with the specifications set out by OIML (International Organisation of Legal Metrology), ensuring that South Africa aligns with global standards.
