Adoption by Endorsement
Adoption by endorsement for the latest version of this international/national standard and the previous adopted edition remains effective for 2 years starting from the date of last international update
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.
