Consumer Council conducted accuracy test on fuel metres at petrol stations


Consumer Council conducted an accuracy test on fuel metres at 18 petrol stations in Macao, only 1 sample was found to exceed the required standard and the test result has been passed to related department for follow-up. The Zhuhai Supervision Testing Institute of Quality and Metrology was commissioned by the Council to conduct the mentioned test on petrol machines at 18 petrol stations in Macao. According to national standard JJG443-2206, each fuel metre was tested thrice consecutively for the calculation of the difference between the actual output volume of fuel and the volume stated on the metre, and the average of the three tested results should not exceed +/-3%. Petrol station staffs were asked to randomly pick one fuel metre at each station to be examined by pumping 20 litres of petrol into a testing container and examined by a representative from Zhuhai Supervision Testing Institute of Quality and Metrology to calculate the difference between the actual output volume and the volume stated on the metre. Test results showed that 1 sample was found to exceed the standard and recorded an inaccuracy rate of +0.313%. Although the actual output volume is greater than the stated volume and consumers' rights are not infringed, the involved oil company has been notified to adjust its facilities at petrol stations to ensure accuracy of fuel pumps and metres. The Council indicates that most samples meet the required standard, the oil and petrol industry is called on to carefully monitor the accuracy of petrol machines for the sake of protecting the rights of consumers.
