Made from very high quality High-tensile Steel. All UKAS Hanger Weights are calibrated here at JWS to the specification listed below. 1.0kg Hangers have a maximum stacking height of 500-510mm.
UKAS Test Weights are sent to Trading Standard to be tested and Certificated.
They must have a Serial Number stamped onto the weight.
Only one UKAS Certificate is needed per batch of weights on the same order. Please remember to add this to your basket available back on the Test Weights page.
