GB/T 33519-2017

This standard provides a systematic classification framework for brakes based on design, function, and application, covering types such as drum, disc, band, and electromagnetic brakes. It is applied in the mechanical engineering and manufacturing sectors to standardize terminology and categorization for design, procurement, and quality control of braking systems in vehicles, industrial machinery, and lifting equipment. The standard ensures consistent communication and technical alignment across engineers, suppliers, and testing laboratories.
