WebThere are two types of flammability tests according to UL 94: horizontal and vertical, which consist of measuring the burning time of a plastic sample fixed horizontally or vertically, after it has touched the flame of a burner during the time specified in the corresponding standard. Horizontal Flammability WebA number of hydrogen's properties make it safer to handle and use than the fuels commonly used today. For example, hydrogen is non-toxic. In addition, because hydrogen is much lighter than air, it dissipates rapidly when it is released, allowing for relatively rapid dispersal of the fuel in case of a leak. Some of hydrogen's properties require ...
