ISO 19291:2016描述了基于高频线性振动试验机的试验方法，以确定摩擦量，如摩擦、磨损、承载能力和液体润滑剂（油）和一致润滑剂（润滑脂）在球-盘接触几何结构中的极压行为。

ISO 19291:2016 describes test methods based on a high-frequency, linear-oscillation test machine to determine tribological quantities like friction, wear, load carrying capacity and extreme pressure behaviour of liquid lubricants (oils) and consistent lubricants (greases) in the ball-on-disk contact geometry.
