ISA-RP74.01:1984

Furnishes design criteria conducive to simplified specifications and provides recommendations for installation, calibration, and maintenance of continuous belt, weighbridge-type scales. This recommended practice provides an effective base of comparison for scale suppliers, establishes minimum values, and ensures that a scale specification and purchase incorporates the essentials to satisfy a particular weighing job. It permits early belt conveyor design, with the full knowledge of the weigh scale configuration, regardless of the manufacturer. Scope: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. Purpose: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.
