ASTM E959-83(2010)

Standard Test Method for Characterizing the Performance of Refuse Size-Reduction Equipment

SIGNIFICANCE AND USE
Throughput, power and energy requirements, and product size are key parameters that describe the operation and performance of solid waste size-reduction equipment.
This test method can be used to determine if the size-reduction equipment is operating within specifications and meeting performance criteria.
Having determined the parameters given in 5.1, the equipment that has been subjected to the test may be compared to other equipment similarly tested in order to establish relative levels of performance among equipment.
The basic test period is a continuous two to four h duration. The use of several test periods may be warranted to assess adequately the performance of size reduction equipment.
SCOPE
1.1 This test method covers measuring the performance of solid waste size reduction equipment.
1.2 This test method can be used to measure the flow (that is, throughput) of solid waste through the size-reduction equipment, energy usage of the size-reduction device, and particle size of the shredded product.
1.3 This test method includes instructions for measuring energy usage, solid waste throughput, net processing time, and particle size distribution.
1.4 This test method applies only to size reduction equipment that produces a shredded product with a size corresponding to 90 % cumulative passing in the range of 0.5 to 15 cm (0.2–6 in.) on an air-dry weight basis. For material with nominal sizes outside of this range, the precision and bias statements for particle size designation (Section 15) may not apply.
1.5 This test method can be applied to size reduction equipment located anywhere within a processing line.
1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.6.1 Exception—The values given in parentheses are for information only.  
1.7 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. See Section 7 for specific hazard information.
