The Greatest Guide To consumer product testing laboratories

The main fall in the Nolan X-402GT on towards the flat anvil registered 126 G and the next drop registered 177 G. I didn’t history the length of time in milliseconds that it will take to dissipate the Electrical power, also a vital consideration.

Despite having just 30 designs in their original test group, the scientists spotted developments beginning to arise.

When the accelerometer reads a lot more than the utmost allowable g’s (generally 300 g’s), the helmet fails most standards. Distinct anvil shapes replicate unique objects your head might come into connection with in the real environment. Examine more about anvils below.

Just about every headform has a significant matrix of Proportions that happen to be accustomed to program the pc-controlled equipment equipment that make the headforms. This assures the accuracy with the typical headform measurement and pounds.
