This International Standard specifies the characteristics of liquid hydrogen refuelling and dispensing systems on land vehicles of all types in order to reduce the risk of fire and explosion during the refuelling procedure and thus to provide a reasonable level of protection from loss of life and property. This International Standard is applicable to the design and installation of liquid hydrogen…

Specifies a method for the determination (by high-performance liquid chromatography) of the piperine content of ground pepper, whole pepper and oleoresins of pepper. The method enables a separation and, if necessary, the determination of the other alkaloids of pepper (isochavicine, isopiperine and piperittin).

This part of ISO 3888 defines the dimensions of the test track for a closed-loop, severe lane-change manoeuvre test for subjectively determining the obstacle avoidance performance of a vehicle, one specific part of vehicle dynamics and road-holding ability. It is applicable to passenger cars as defined in ISO 3833 and light commercial vehicles up to a gross vehicle mass of 3,5 t. An informative…
