About This Product
A rigidity test shows how well a protective helmet resists deformation under force. The helmet is placed without its head-form between two flat horizontal plates, given a small initial load and then a major load applied over a set time. The change in the helmet dimension under each load is measured and compared with specified values. In a testing laboratory the apparatus shows students how applied load, deflection and specified values are used to judge a safety product. The Rigidity Tester can be supplied and exported to buyers in Fiji, Togo, Mexico, Mali, Barbados and Kyrgyzstan.
Frequently Asked Questions
Q1. What does the Rigidity Tester measure?
It measures the change in dimension of a helmet under an initial load and then a major load, read as deflection on a scale and pointer.
Q2. How is the major load applied?
Disc-shaped dead weights are placed on top of the loading plate assembly in specified steps. The weight of the assembly itself is the initial load.
