Filter Paper Test (for Petrol)
- Clean the mouth of the dispensing nozzle to remove stains.
- Put a drop of petrol on the filter paper from the nozzle.
- It should evaporate in about 2 minutes without leaving a stain on the filter paper. (If the area of the filter paper where the drop of MS was put remains pinkish, it is the colour of the MS and not any stain). If a stain is left on the filter paper, there is a possibility of adulteration.
Customer can immediately lodge a complaint if Filter paper is not available at Retail outlet for testing of Petrol. It is the duty of the Dealer to provide the filter paper on demand by the customer. Density Check (for Petrol and Diesel, including branded fuels)
A 500 ml jar, calibrated hydrometer & thermometer and ASTM (American Society for Testing of Materials) conversion charts are required to carry out density test. A hydrometer is a very simple instrument for measuring density of any liquid, which would be different for petrol and diesel.
- Fill about 3/4th of the jar with the product taken through the nozzle of the Dispensing unit.
- Dip the thermometer and the hydrometer in the jar and record the temperature and density.
- The actual density observed is then converted into density at 15 degree centigrade with the help of the conversion chart. This converted density is then compared with reference density taken from the register maintained at the Retail Outlet.
