Road vehicles. Test of braking systems on vehicles with a maximum authorized total mass of over 3,5 t using a roller brake tester - Air over hydraulic and purely hydraulic braking systems1 Scope This part of ISO 21069 describes a procedure that generates comparable measurement results in roller brake testing, such that the efficiency of the service braking system can be assessed reliably wherever the roller brake tests are performed. The following items are covered in this part of ISO 21069: symbols and definitions; test methods; test conditions; test equipment required; accuracy of test equipment; data recording and calculation

Rolling Stock and Fixed Installations

for use in the petroleum industry

ISO 15781 specifies how to measure and report the shooting time lag

These include CNC composition

The standard will bring the following advantages to those who adopt it:

their responses are sensitive to signal and insensitive to noises

Thus BS EN 4612-013 eases the production of nickel-plated electrical cables and assists in manufacturing a standardized product that has global acceptance in the market
