Spatial measurements for comparison against reference values

BS EN 13848-1 provides assessment of excursions in the vertical and lateral planes from the mean or designed geometrical characteristics of specified parameters which give rise to safety concerns or have a correlation with ride quality

generally known as “mine cars”

BS EN 12817 is applicable to LPG pressure vessels

and gives examples for the determination of percentage of imperfections

Road vehicles. Brake lining friction materials. Friction behaviour assessment for automotive brake systems Ingestion-build-264231 Spatial measurements for comparison against1 Scope This International Standard describes a test procedure for assessing the influence of pressure, temperature, and linear speed on the coefficient of friction of a given friction material in combination with a specific mating component (rotor or drum). This International Standard is intended for use when comparing friction materials under the same conditions, or when controlling friction behaviour against a specification or certain performance
