Ohaus SD200L Bench Scale When performing an aggregate impact test to test toughness of road materials, there are several steps to take to insure the materials will be able to stand the test of time. One such step is to measure the mass of the materials after they have been oven dried. Having a reliable scale in the lab is crucial for getting an accurate measurement. This means the scale has to be correctly calibrated to get an accurate reading.
There are many other opportunities you might encounter in the lab in which you will need to weigh samples of soil, aggregate, concrete, etc. The accuracy of testing relies on the scale being used and the technician reading the scale, especially if it’s a mechanical scale. Other tips for helping maintain the accuracy of a scale’s readings are to maintain the temperature of the lab, air currents in the lab, and maintaining low vibrations in the laboratory. It’s important to calibrate your scale often, as moving or adjusting the scale can also affect the readings.
