The municipality of Dubai has launched a campaign aimed at verifying weighing devices at jewellery shops to protect consumers, Gulf News has reported. Municipality inspectors are now conducting random checks during which they will approve or reject the devices to ensure that they are up to standard. A yellow label will be put on the machines that comply with the technical specifications approved by Dubai Central Laboratory (DCL), while those rejected will have a red label until they are repaired and verified. "The authority will issue verification signs and seals bearing the logos of both parties, which shall be fixed on the measuring instruments according to technical regulations and procedures. Gold traders should know the required specifications of measuring equipment," said Fareed Ismaeel, head of standards section at Dubai municipality.
