As mentioned before, the ECE 22.05 standard administered by the Economic Community of Europe is the most common internationally. Both ECE and DOT standard test for energy absorption and helmet rigidity at greater impact speeds, but ECE standard requires that a sample from each manufacturing batch be re-tested for compliance for any manufacturer.
We bought an ECE Testing Machine for designing helmet and cost us around US$100,000 from Taiwan. Please see the video for this Shock Absorption Test. When manufacturing a batch or a certain amount of helmets, we need randomly to take one helmet for testing and give data details together with the shipment.
