(Test Method)Standard Test Methods for Conducting Performance Tests on Mechanical Conveying Equipment Used in Resource Recovery Systems (Withdrawn 2005)
Standard Test Methods for Conducting Performance Tests on Mechanical Conveying Equipment Used in Resource Recovery Systems (Withdrawn 2005)
SIGNIFICANCE AND USE
These test methods may be used to measure the equipment performance.
These test methods are applicable when the conveying equipment is of sufficient length and is accessible for taking the samples and measuring the speed, or when the discharge is accessible to collect a sample in a given length of time. Not all pieces of equipment in a processing plant may be accessible; therefore, the input or total of inputs to adjacent upstream equipment/output or total of outputs of adjacent downstream equipment may be used to determine the throughput of the conveying equipment in question. Judgement must be used to determine any loss of material or changes in bulk density.
SCOPE
1.1 These test methods include descriptions for conducting and reporting throughput and electrical power tests on mechanical conveying equipment for municipal solid waste and recovered products from resource recovery systems. Other aspects of performance testing such as spillage, conveyor tracking, dusting, slippage, transfer points, etc., should be considered in the interpretation of the results. These test methods can be used on equipment handling raw refuse, processed refuse, magnetic scrap metals, nonferrous scrap metals, mixed glass, and residues or tailings. These test methods may also be used for materials in other industries.
1.2 These test methods cover mechanical conveying equipment including apron, belt, drag, flight, screw, slat, and vibrating conveyors and bucket elevators.
1.3 These test methods are applicable specifically to the resource recovery industry since municipal solid wastes are heterogeneous mixtures and the composition and bulk densities vary considerably depending on many factors. Because of the varying composition of municipal solid waste, a number of samples must be taken to determine accurately the performance of the mechanical conveying equipment.
1.4 Test methods for determining the approximate as-conveyed bulk density of the material and for determining the electrical horsepower input of the equipment motors are also included.
1.5 It is intended that the tests be made and reported by personnel trained in the proper application and use of the various instruments and methods involved.
1.6 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For hazard statement, see Section .
WITHDRAWN RATIONALE
These test methods include descriptions for conducting and reporting throughput and electrical power tests on mechanical conveying equipment for municipal solid waste and recovered products from resource recovery systems.
Formerly under the jurisdiction of Committee D34 on Waste Management, these test methods were withdrawn in February 2013. This standard is being withdrawn without replacement due to its limited use by industry.
