LTA said the OBU meets the relevant global benchmarks for electronic devices, and when installed properly, is safe and reliable in Singapore’s operating environment.The Land Transport Authority has refuted allegations that the on-board units for the next-generation Electronic Road Pricing system, or ERP 2.0, had failed to meet international standards.
The IEC-60068 is a method for the environmental testing of electronic equipment, while the IEC-60529 rates the resistance of electronic devices against the intrusion of dust and liquids.The authority reiterated Transport Minister Chee Hong Tat’s parliamentary reply to Workers’ Party MP Louis Chua’s question on May 8 about whether the OBU meets the minimum standards of the Automotive Electronics Council Q100 requirements for reliable operations in Singapore’s climate.
A more relevant comparison with the processing unit, said LTA, is a smartphone, which functions similarly like a mini-computer. For the same reason, the authority does not recommend placing the processing unit on the dashboard, as the temperature there could reach 50 to 52 deg C on a hot day, compared with 38 to 39 deg C at the footwell.
