Local LP gas fiasco: propane-butane ratio not standardized

The exact ratio of propane to butane in LP gas in cylinders has not been standardised, director of engineering standards of the Sri Lanka Standards Institution (SLSI) M.S.S. Fernando said.

He claimed that measurements used to measure the quality of domestic LPG in Sri Lanka are outdated.

Fernando said steps are being taken to change the existing measurement methods adding that at present there is no standard measurement of the composition of LPG.

Even though there is a standard to measure the pressure of the LPG, the SLSI is handicapped to regulate it, he said.

“Currently active LP gas pressure standards are 1,430 kPa for propane and 485 kPa for butane. In addition, the temperature of the gas should be 37.8 degrees Celsius. Steps have been taken to update these standards and they will be published soon,” he said.
