Purpose and scope

The purpose of this recommended practice is to furnish design criteria inducive to simplified specifications and to provide recommendations for installation, calibration, and maintenance of continuous-belt, weighbridge-type scales. The recommended practice will provide an effective base of comparison of scale suppliers, will establish minimum values, and will ensure that a scale specification and purchase incorporates the essentials to satisfy a particular weighing job. It will permit full knowledge of the weigh scale configuration (regardless of the manufacturer) early in the design stages of the belt conveyor.
