(Practice)Standard Practice for Sampling Waste Streams on Conveyors
Standard Practice for Sampling Waste Streams on Conveyors
SIGNIFICANCE AND USE
4.1 This practice can be used in sampling ash from a kiln or incinerator, soils, and process waste from conveying systems, such as a conveyer and vertical lifts. Some slurries, such as the bottom solids, can be sampled from the quench waters at the end of a kiln.
4.2 This practice can be used to determine material balances for burner efficiency studies and compliance studies.
4.3 This practice can be used on lifts, sloping, and horizontal conveyor systems. The type of conveyor and the amount and type of sample required will dictate the type of sampling equipment required to get a representative sample.
4.4 The sample is taken directly from the conveyor before emptying into the waste container or pile for disposal or recycling using a scoop, dipper, or shovel depending upon the sample requirements (see Practice D5633). The sample is then put into the sample container for analysis.
4.5 The place, quantity, frequency, and time of sampling is dependent upon the conveying system equipment, data quality objectives (DQOs) (Practice D5792), work or sampling plan (see Practice D5283 and Guide D4687), and analysis to be run.
4.5.1 Large particles can be mechanically excluded on a belt system. Large particles may accumulate at the bottom of an inclined/sloped belt system. Therefore, steps, if possible, need to be taken so that particles of all sizes have equal chances of being sampled.
4.5.2 The number of samples and sample time is dependent upon the system, the precision required, the decisions that are to be made, the cost, and the degree of heterogeneity of the material (see Guides D5956 and D6311).
4.5.3 In general, the ideal sampling location is nearest to the point of generation since temperature, oxidation, and air movement may change some samples with time.
4.6 The practice does not address issues related to the heterogeneity of the sample.
SCOPE
1.1 This practice describes standard procedures for sampling waste on open and closed conveying systems and is applicable to any waste material that can be conveyed to a waste pile or container. The conveyor system can be a vertical (vertical lifts), sloped, or horizontal type.
1.2 This practice is intended for particles and slurries, which can be sampled using scoop, dipper, or shovel type samplers.
1.3 The practice is not intended for large size sample constituents, such as boulders, large rocks, and debris.
1.4 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.
1.5 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.
