ISO/IEC 19479 defines refinements to the learner mobility achievement award (LMAI) model for representing the digital diploma supplement (DDS)

On lines equipped with ERTMS/ETCS Level 2 there may be some additional signs needed for maintenance

all the curves for the logarithm of the stiffness in torsion as a function of temperature have a similar appearance

in most cases an additional regenerative braking (recuperation or regeneration of braking energy) function is installed

Plastics piping systems. Glass-reinforced thermosetting plastics (GRP) based on unsaturated polyester resin (UP). Report on the determination of mean abrasion after a defined number of test cycles seo-ignore ISO/IEC 19479 defines refinements to1 Scope This Technical Report describes a method for determining the mean abrasion of the inner surface of glass reinforced thermosetting polyester resin (GRP) pipes conforming to EN 14364, measured after a defined number of test cycles of a specified water abrasive mixture. NOTE The test is performed on a semi circular channel pipe test piece.
