5、5 Superseding J1702 NOV2007 Self-Propelled Sweepers Sweep-Ability Performance RATIONALE The document has been revised to update the referenced documents and clarify some statements. 1. SCOPE This SAE Standard establishes a method of disclosing the sweep-ability performance of self-propelled sweepers

6、 that use broom means for sweeping and collection, together with either a mechanical- or pneumatic-conveyance system for the transfer of “sweepings” into a collection hopper. 1.1 Purpose The purpose of this document sets out to describe a test practice for gauging the sweep-ability performance by sw

7、eepers described in SAE J2130-1 together with a format for the presentation of the test results. The document can be used to disclose or compare particular operating performance criteria for similar conditions. 2.

DEFINITIONS 3.1 SWEEPER A self-propelled sweeper is primarily designed to sweep material fro

10、m highways, parking lots, airport complexes, industrial and construction sites, and during road maintenance work. The sweeper may use broom means to dislodge and direct material into a collection mechanism, which may be mechanical, pneumatic, or a combination of both systems to convey the swept mate

11、rial into a collection hopper. 3.2 TEST SITE Level paved area (r3%) on which the sweeping test is conducted. 3.3 TEST MATERIAL Prepared materials used in the sweeping tests. 4. TECHNICAL REQUIREMENTS 4.1 Test Method There are three separate tests - using an assortment of consistent test materials fo

12、r each test. 4.2 Condition of Sweeper Prior to a test, the sweeper shall be set at the normal operational settings according to the manufacturers specification. Brooms and swept material containment curtains, etc., should be in like-new condition. Where the sweeper has variable duties of operation d

13、escribed in its instruction manual, then the sweeper shall be operated at its maximum-duty cycle. These settings shall be stated in the test report. Dust suppression systems if provided shall be active during the test. 4.3 Weather Conditions Weather conditions shall be dry, with a wind speed less th

14、an 20 km/h and such that it does not disturb objects on the test course as depicted in test 3. 4.4 Test Site 4.4.1 Site During the test run, the sweeping brooms (channel(s) or gutter broom(s) shall be directed along the guideline depicted in the test site pattern in 4.4.3. 4.4.2 Site Preparation The

15、 position and pattern of the test material placement zones is shown in the test site pattern in 4.4.3. If the type and sweeping width of the sweeper being assessed lacks sufficient capacity, then the zone size and materials can be varied, in which case full descriptions should be recorded with descr

16、iption of the criteria recorded in the test report. 4.4.3 Test Site Pattern See Figure 1. SAE INTERNATIONAL J1702 Revised MAY2014 Page 3 of 7 FIGURE 1 - TEST SITE PATTERN 4.5 Test Material 4.5.1 Test Material Pattern The test material defined in 4.5.2 shall be placed in the three placement zones. Th

17、e test material may be arranged to the right or to the left of the guideline to suit the construction and layout of the sweeper. 4.5.2 Test Material Tables 1, 2, and 3 define the type and quantity of test material for tests 1, 2, and 3. The test material media and quantities may be varied according

18、to the type and capacity of sweeper being assessed. The substituted test material quantity and placement shall be stated in the test report.

24、e or at a specific speed of operation. Test material for test 1 and test 2 shall be dry. If this is not possible, tests may be made with wet sand, in which case this must be stated with an indication of water inclusion in the test report. Test objects in test 3 that are beyond the capability of the

25、sweeper may be removed from the test course but shall be recorded as not swept material. Any test material or objects being deflected out of or carried beyond the test course shall be reported as not “swept” in the test report. 4.7 Travel Speed During each test run, the sweeper shall be driven at a

26、predetermined speed or timed from start to finish. In order to assess any quantities of residual test material being carried beyond the test course finish line in a speed related test, the sweeping mechanisms shall be disabled at the finish line. For a time-based test, the time taken to disable the

27、sweeping mechanism shall be recorded within the total test time. 5. RESULTS 5.1 Test Analysis All not-swept test material described in 4.5.2 resulting from each test run shall be collected and compared to the total amount initially distributed throughout the three test material placement zones (X, Y

28、, and Z). 5.2 Ratings In test 3, each object is to be rated using the score rating values in Table 3 in the test material schedule. The maximum value is 100 or 100% if all objects are swept and collected. 6. TEST RESULT PRESENTATION In order to present the results of a sweep-ability performance test

29、, a suggested test sheet of the following format could be adopted (Figure 2).
