    - Legal Metrology

Government is responsible for ensuring the orderly conduct of commerce, the protection of all participants in the market for goods and services and protection of consumers by ensuring equity and correctness in all trade based on measurements of quantity as a basis for the transaction, and that products are correctly labelled.

Legal Metrology is responsible for the implementation of the requirements of the Trade Metrology Act, 1973 and Regulations.
 
NRCS has regional Legal Metrology offices in Pretoria, Cape Town, Durban, Port Elizabeth, and Bloemfontein. Staff at all offices is qualified to undertake inspections under the Trade Metrology Act.

Protecting the Consumer
All activities of Legal Metrology are intended to protect the consumer we constantly:
  • Conducts surveillance inspections at all levels (manufacturer, importer, distributor and retailer) in the market to ensure that consumers receive fair measure and legal requirements are met.
  • Continually verifies the accuracy of measuring instruments and measures;
  • Calibrates measures and measuring instruments on site and in the laboratory;
  • Conducts technical training courses for its own staff and businesses involved in installation, maintenance, verification and calibration of measuring instruments;
  • Takes immediate action to stop the sale of goods when legal requirements are not met.

In order to provide further protection to the consumer Legal Metrology also operates a voluntary pre-pack certification scheme – the “e” Mark Scheme. In order to participate in the scheme packers must prove that they consistently meet requirements regarding quantity packed and labelling, and that they have adequate management systems in place to ensure that they continue to comply.

Legal Metrology continually strives to ensure that its standards for inspection and competence of employees are world class, through accreditation to SANS17020 - General criteria for the operation of various types of bodies performing inspection. Accreditation provides formal recognition of the competence of the inspection function.

Consumer and Industry Watch Dog

Consumers are urged to lodge complaints regarding on any of the above whereby the Inspectors will do a reactive inspection and solve the complaints.

Complaints
The most common complaints involve:
  • short mass/volume;
  • Use of non-approved or un-certified measuring instruments.
Short mass/volume
Most products are packaged before sale, and must meet requirements for allowable tolerances in measurement.
 
Un-certified measuring instruments complaint:
Measuring instruments used in trade must be certified at regular intervals or after repairs by a SANAS accredited laboratory. The operator is issued with a certificate and a certification mark is applied to the instrument.
 
Un-approved measuring instrument
By law all measuring instruments used in trade have to be type approved. When an instrument is type approved it is given a pattern approval number, which has to appear on every replica in the format SA..XXXX (a number) that corresponds with the approved pattern.
 
If you have a concern with one of the above, or any other matter involving trade measurements, please contact the nearest regional office in your area.
