Test weights use to check safe working loads of equipment (cube shape) 1

[ethanhunt118]

Hello, Good Morning,

We are making some test weights, for example 250kg by filling them with iron. ( just a testing cube shape)

I would like to know if there is a procedure of certifying them properly ? or if there is any regulation that governs that please

Hope you can help.
Thank you kindly

Sure. Call a local instrument calibration service, and tell them what the test masses you would like certified are. We have a scale in our shipping dept. that weighs to 2200 lbs., for weighing shipping pallets, and have it regularly certified by a local shop. They bring a set of weights that are certified (traceability to NIST) and run a calibration check.

thanks for reply. is that something required by law ?

Um, not necessarily.

If your test weights are for calibration for load testing of some fixtures, or for verifying that a forklift can lift a load to a certain height in a certain time, or some other QC test, then no.

But if your test weights are meant to establish, say, the weight of gold bullion you are selling, or grain shipments, or some other commodity, for which you are going to charge (or will be charged) for in a monetary sense, then your local jurisdiction (dept. of weights and measures, dept. of trade, the name may vary) may have something to say about it, and about how accurate your test weight must be.
