In addition to the testing of weighing scales and balances there are many other uses for calibrated test weights including:
LOLER (Lifting Operations and Lifting Equipment Regulations) testing or proof load testing - This involves the periodic testing, normally to one-and-a-half times the lifting equipments rated, safe working load, by test weights, strain or load gauges, this includes all types of lifts and hoists.
Equipment Testing - Calibrated test weights or force gauges can be used to determine how much force it takes to operate a lever, activate an emergency stop, open a gate, a lid or a top from a bottle etc...
Material Testing or destructive testing - what force or weight does it take to tear material, break a cord or snap a widget?
