ASTM E1108-86(2017)
(Test Method)Standard Test Method for Determination of the Recovery of a Product in a Materials Separation Device
Standard Test Method for Determination of the Recovery of a Product in a<brk/> Materials Separation Device
SIGNIFICANCE AND USE
5.1 This test method is used to document the ability of a solid waste resource recovery separator to capture the component(s) of interest in the desired process stream.
5.2 The recovery determined in this way is used in conjunction with the purity of the product, as described in Test Method E889.
SCOPE
1.1 This test method covers the determination of the recovery of a desired product in a device processing solid waste for the purpose of concentrating a component of interest. The recovery is determined with respect to the amount of the desired component in one output stream (accepts) as opposed to another output stream (rejects). The results of this calculation determine the effectiveness of component separation when coupled with a measure of product purity as described in Test Method E889.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 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, health and environmental practices and determine the applicability of regulatory limitations prior to use. Specific precautionary information is given in Section 6.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
