Heavy Capacity​


Is your truck scale being tested properly?

The scale industry is governed by the rules set up by the National Institute of Standards (NIST).  These rules tell us how to design and test scales.  These rules have been developed over the last 100 years based on problems commonly found when testing scales.


Handbook 44 requires truck scales, or any scale over 40,000 lbs to be tested to 12½ % of capacity with certified test weights and then further tested to 25% of capacity with a combination of certified weights and unknown weight – such as the truck transporting the weights.


Does your scale company use enough weight to test your scale to the weight recommended by NIST?  


Left Coast Scales services your scales properly with at least 20,000 lbs of certified test weight and then to a total test weight of at least 42,000 lbs.
