ASTM E1109-86(2009) pdf free.Standard Test Method for Determining the Bulk Density of Solid Waste Fractions.
ASTM E1109 determines the bulk density of various fractions from the resource recovery processing of municipal solid waste. It is intended as a means of characterizing such fractions and for providing data useful to designers of solid waste processing plants.
ASTM E1109 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. Specific precautionary information is given in Section 7.
4. Summary of Test Method
4.1 A sample of a solid waste stream is Lamped in a cubical container of known volume and then weighed. Bulk density is calculated from the weight of the contents and volume of the container.
5. Significance and Use
5. 1 This test method describes a physical property of solid waste in processing facilities: a property that characterizes the solid waste streams and hence the operation of resource recovery separators and processors.
5.2 The bulk density is an important property ftr the design of materials handling equipment, separators. and processors.
6. Apparatus
6. 1 Balance—A balance or scale accurate within 0. I % of the test load at any point within the range of use. The range of use shall he considered to extend from the weight of the measure empty to the weight of the measure plus its contents.
6.2 Cubical Measure, with internal dimensions approximately 6() by 6() by 6() cm (24 by 24 by 24 in.) provided with handles. The interior surfaces of the measure shall he nonabsorbent to moisture.
N0TF I—A satisfactory weigh box has been constructed of ¾ in. (1.9 cm) exterior grade plywood with the tinished surface on the inside.
Reinforcing strips, approximately 5 cm (2 in.) wide and 1.3 cm (½ in.) thick were fastened to the outside walls: two of them in a way to provide handles.
6.3 Larger cubical weigh boxes shall be used as necessary to accommodate large particles of material. No particle larger than two-thirds the length, height, or width of the weigh box shall be put into the weigh box in determining the hulk density.
7. Precautions
7.1 This procedure calls for the handling of solid waste and its processed fractions. Bccausc the origin of all the materials is generally unknown, workers must use proper safety precautions when handling samples. Workers shall wear gloves and safety glasses. When appropriate, dust masks shall be worn. Workers must be cautioned to wash their hands thoroughly before eating or smoking.ASTM E1109 pdf download.
