Scope
Content
This recommended practice provides a method, test set-up, and test conditions for brake hydraulic component flow rate measurement for high differential pressure (>5 bar) flow conditions. It is intended for hydraulic brake components which affect the brake fluid flow characteristics in a hydraulic brake circuit, that are part of a circuit for which the flow characteristics are important to system operation, and that are exposed to high operating pressure differentials (in the 5 to 100 bar range). Typical applications may include measurement of flow through chassis controls valve bodies, orifices in the brake system such as in flow bolts, junction blocks, and master cylinders, and through brake pipe configurations.
Rationale
Content
This recommended practice is intended to provide a standard method, test set up, and test conditions for measuring flow characteristics of brake fluid through brake components in a hydraulic brake circuit, in a high pressure differential flow regime. It maps flow rates through the test specimens, relative to the pressure differential across the test specimen. Data generated in accordance to this standard are intended to be useful towards hydraulic brake response time modeling, towards specifying flow characteristics in brake components to meet desired hydraulic system response characteristics, and diagnosing the contribution of individual hydraulic components to system level response behavior.
