Becauseit may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In

United States15.2 This test method is also used in conjunction with measurements of th

15、e performance of materials separators (particularlyrecovery and purity). As such, throughput should not generally be measured by sampling the feed since this may change itsperformance. Processing equipment that does not perform separations can be sampled at either the feed or product streams.6. Appa

16、ratus6.1 Collection BinsSeveral size collection bins are required. The size is determined by the size of sample, which in turn, isdetermined by the throughput of the plant. Some streams can be sampled into drums or barrels.6.1.1 All containers must be clean and in good mechanical condition, and not

17、have rusting, flaking, or mechanically weakenedsections. Containers should be cleaned with water or an air hose prior to use. (WarningAir hoses must be used with appropriatesafety equipment to avoid personal injury.)6.1.2 The tare weight of the containers should be clearly marked with paint and chec

18、ked periodically. Provision may be madefor bin covers for the sampling and containment of materials that can be blown or spilled. Covers must be marked to indicatewhether or not they are included in the tare weight of the container.6.2 ScalesThe type and size of scales varies with the size of the sa

19、mples obtained. Containers as small as perhaps a drum toas large as perhaps a tote bin, roll-off container, or even full truck may be used. All scales should have a precision and accuracyof 60.1 %.60.1 % of reading.6.3 StopwatchFlow times are determined with a stopwatch capable of measuring to the n

20、earest 0.1 s.6.4 MiscellaneousA variety of scoops, shovels, brushes, and similar tools are required to transfer materials.7. Precautions7.1 If samples are taken by transferring materials from a conveyor belt, it is essential to measure the belts speed and useappropriate tools to be certain that all

21、of the material, especially including fine particulate materials, are transferred.7.2 Because the origin of all of the materials in solid waste is generally unknown, workers must use proper safety precautionswhen handling samples. Workers shall wear gloves and safety glasses. When appropriate, dust

22、masks shall be worn. Workers shallbe cautioned to wash their hands thoroughly before eating or smoking.7.3 Safety precautions shall be taken when collecting samples or working near moving equipment.8. Sampling8.1 Samples are taken after the equipment has reached a steady-state operation. A steady-st

23、ate operation is arbitrarily assumedafter the equipment is operating for at least 30 min under what are considered to be normal conditions, or as otherwise agreed. Thecomposition and type of feed may not be changed during this time.8.2 After steady-state, samples are taken at agreed intervals.8.3 Th

24、e sample is taken by whatever method in Section 11 suits the separator or processor being sampled.9. Test Specimen and Samples9.1 The size of sample is taken in relation to the particle size of the material or estimated throughput of the process, or both.9.1.1 The minimum size of sample is determine

25、d by its particle size in accordance with Practice D75, or by 9.1.2 or 9.1.3,whichever is greater.9.1.2 For particle sizes greater than 90 mm (not included in Table 1 of Practice D75), the size of sample is 250 kg (550 lb).9.1.3 The minimum weight of sample shall correspond to the estimated throughp

26、ut for 1.0 min or the minimum weight will bedetermined by the procedure in Test Methods E868.9.2 Test samples corresponding to 9.1 are weighed without subdivision.9.3 Three test samples shall be taken for each randomly chosen sampling time. Two of the samples will be weighed; the thirdshall be retai

27、ned and weighed if the calculated throughputs based on the first two differ by more than 10 %, as described in 12.4.9.4 If possible, both binary and polynary separators should normally be sampled at the output sides.10. Conditioning10.1 Weigh the samples immediately after they are taken. Take precau

28、tions to ensure that they neither gain nor lose weight fromnatural drying or drainage or from ambient moisture or dirt.11. Procedure11.1 Use separate procedures for sampling conveyors, chutes, or discharge containers.11.2 Conveyors:E1107 15211.2.1 Conveyors are most conveniently sampled by catching

29、the discharge at the end of the conveyor in the tared container.Take care that the bin is wider than the width of the conveyor and the entire contents of the belt width is collected.11.2.2 Conveyors can also be sampled by stopping the belt and removing a portion of the belt load. In this method, det

30、erminethe belt speed by timing the movement of a mark on the belt as it passes between two marks on the sides of the conveyor. Measurethe distance between the latter two marks and use the measurement to calculate the belt speed. Alternatively, use a tachometer fordetermining the speed of the belt. S

31、top the conveyor and shovel the material lying on a predetermined length of the conveyor intoa suitable tared container. Take care to include all fine particulate materials. Also, take care to ensure that the belt load moves atthe same speed as the belt and is not hindered by the sides of the convey

32、or, thus causing slippage.11.3 ChutesSample material falling through a chute by placing a tared container of suitable size under the chute and collectingthe material for a predetermined length of time, measured with a stopwatch to the nearest 0.1 s. If it is not possible to sample thedischarge of a

33、chute, a diverting chute member may have to be added along with a gate. Exercise care at the discharge ends ofchutes to ensure that all of the material flowing is collected in the container. Flexible spouts may be fastened (even if temporarily)on the ends of the chutes and directed into the containe

34、rs.11.4 Discharge ContainersSample discharge points by using a tared container to collect the material. Preferably, fasten aflexible spout or a diverter to the discharge point to the usual collection bin so that the flow can be suddenly diverted to the taredcontainer without significant spillage. Wi

35、thout such a flexible spout, it may not be possible to time accurately the discharge.11.5 Sampling and weighing must be done without spilling any of the material. Note any spillage more than dusting. Spillageof more than 1 % of the collected sample, visually estimated, is reason to discard the sampl

36、e and start over.11.6 Weigh the tared containers containing the samples immediately and record the filled gross weights. Record weights within0.1 % of the total filled weight in accordance with the precautions of 10.1.12. Calculation12.1 Record the following information:12.1.1 Method of sampling (11

37、.2.1, 11.2.2, 11.3, or 11.4);12.1.2 Location;12.1.3 Time of day and date;12.1.4 Tare of container;12.1.5 Weight of filled container; and12.1.6 Special observations.12.2 Calculate the sampling time for the procedure in 11.2.2 as follows:Sampling time5t 5L/Y (1)where:L = length of conveyor swept, andY

40、e conveyor belt to move between these two marks, s.12.2.1 The conveyor speed is in units of meters per second (m/s) and the sampling time t is in units of seconds (s).12.3 Measure the sampling time for other procedures (11.2.1, 11.3, and 11.4) with the stopwatch.12.4 Calculate the throughput, Q, on

41、a wet-weight basis for a processor, sampling either the input or output stream as follows:Q 5W 2A! 3600t (2)where:W = weight of the filled container,A = tare (empty) weight of the container, andt = time of collection of the sample, s.12.4.1 If W and A are in kilograms, Q is in kilograms per hour.12.

42、5 Paragraph 12.4 can be used to calculate the throughput of a processor if the input stream is sampled. However, note theinformation in 9.4.12.6 A binary or polynary separator may be sampled at each of its output streams with all samples taken at the same time andfor equal time intervals. Calculate

43、the throughput for each stream in accordance with 12.4 and sum to obtain the total throughput.13.
