Road vehicles — Pneumatic braking connections between motor vehicles and towed vehicles — Interchang...
Specifies the requirements with concern to vehicle combinations equipped with pneumatic braking systems with two circuits: one control circuit and one pneumatic power circuit. Some figures illustrate shapes and reference quantities of concern. This second edition cancels and replaces the first edition (1975).
Plastics — Determination of bulk factor of moulding materials
Specifies a method of determining the bulk factor of a moulding material from its apparent density in the unmoulded form and its density in the moulded form. Knowledge of the bulk factor is of importance for the calculation of the minimum cavity volume in the design of moulds. The bulk factor is given by the quotient of the density of the material in the moulded form, determined according ISO…
Hydrolysis of the esters by heating, under given conditions, with a standard volumetric potassium hydroxide ethanolic solution, and titration of the alkali in excess. The hydrolysis is carried out in a saponification flask.
Road vehicles — Elastomeric cups and seals for cylinders for hydraulic braking systems using a non-p...
Specifies performance tests of brake cups and seals for braking systems. Requirements relating to chemical composition, tensile strength and elongation of the rubber compound are not included. Applies to moulded seals (cups or double-lipped type gland seals), 60 mm in diameter or less, compounded from high temperatur resistant rubber. This second edition cancels and replaces the first edition (…
Rubber or plastics coated fabrics — Determination of abrasion resistance
Data obtained by this method may be used to predict the behaviour of these fabrics, but not as an absolute criterion. It is preferable to limit the significance of the test by considering it as a means of control only. The method only refers to the abrasion resistance of coating and is useful when comparing materials with the same or similar characteristics. The abrasion is measured by loss in…
Specified is a series of preferred values for the distance scale markings of photographic lenses. The preferred values are given for scales indicating the distance in metres and feet. The infinity mark is also specified.
Alpine skis — Determination of the elastic properties
Specifies laboratory measurement methods to determine the elastic properties of alpine skis. Its purpose is to calculate the resistance of defined parts of the ski to bending and torsion.
Véhicules routiers — Liaisons de freinage pneumatique entre automobiles et véhicules tractés — Inter...
La présente Norme internationale fixe les prescriptions permettant d'assurer l'interchangeabilité entre automobiles et véhicules tractés en ce qui concerne les liaisons de freinage pneumatique.
La présente Norme internationale concerne les ensembles de véhicules équipés de systèmes de freinage à air comprimé comportant deux conduites : la conduite de commande et la conduite d'…
