5 Ounce Certified Test Weight


The 5 Ounce Certified Test Weight is for verifying the accuracy of any scale used for weighing pinewood derby cars. It is not used for calibration.


Eliminate questions and issues at the weigh-in by verifying the accuracy of your scale using this certified test weight. Each weight is guaranteed to be 5 ounces ± 0.006 grams (0.0002 ounces).

Note that this weight can be used to verify the accuracy of any scale, but may not function as a calibration weight for all scales – our scale uses a 200 gram calibration weight.
