Road vehicles — Elastomeric boots for drum type hydraulic brake wheel cylinders using a non-petroleu...
Specifies performance tests for moulded rubber boots used as end closures on drum type brake cylinders. These boots prevent the entrance of dirt and moisture which could cause corrosion and otherwise impair wheel brake operation. Applies to boots of both plain and reinforcement insert types. Requirements relating to chemical composition, tensile strength or elongation at break of the rubber…
Acoustics — Measurement of noise inside motor vehicles
Specifies the conditions for obtaining reproducible and comparable data of noise levels and noise spectra inside all kinds of road vehicles, excluding agricultural tractors and field machinery.
Road vehicles — Brake linings — Resistance to water, saline solution, oil and brake fluid — Test pro...
Specifies a laboratory method for exposing samples to detrimental environments, measuring the effect on strength and shape and comparing the results with those from uncontaminated samples. Applies to drum brake linings and disc brake pads being of organic content and intended for service on road vehicles.
Road vehicles — Brake linings — Seizure to ferrous mating surface due to corrosion — Test procedure
Specifies a laboratory method for conditioning brake linings in an environment that will promote corrosion, and a test method to assess the strength of bond formed by corrosion. For comparison of lining behaviours, it is essential that the material and condition of ferrous mating surfaces be constant and repeatable. Applies to drum brake linings and disc brake pads fitted to the brakes of road…
Road vehicles — Brake linings — Internal shear strength of lining material — Test procedure
Specifies a method of measuring the internal shear strength of brake lining materials. Applies to friction materials for disc brake pads and drum brake linings to be used in road vehicle brakes. A figure shows the principle of the test rig. Describes the apparatus to be used as well as sampling and conditioning.
Road vehicles — Brake linings — Effects of heat on dimensions and form of disc brake pads — Test pro...
Specifies a combined method of measuring disc brake pads to determine their dimensional changes in relation to temperature and their resistance to heat transfer. Applies to disc brake pads which dimensions should not exceed 80 mm in depth, 120 mm in width and 20 mm in thickness, being of integral moulded or bonded type, and the backing plate of solid type.
Road vehicles — Air braking systems — Identification of connections on units
Specifies an identification system for pipe connections on units of air braking systems. The digits designated shall be placed close to the ports on the units. Applies to motor vehicles and their trailers and may also be used for schematic diagrams of braking systems. Shows an detailed example.
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).
