The use of safe paintball barrier netting at paintball playingfacilities is critical to protect non-players from accidental impact of a paintball.This specification is written within the current state-of-the-art of paintball barrier nettingtechnolo

4、gy. The intent is to revise this specification whenever substantive information becomesavailable which justifies revising existing requirements or adding new requirements.1. Scope1.1 This test method is designed to evaluate paintball barrier netting that may be used to delineate playing fields, chro

5、nographareas, target ranges, and other “goggle-on” areas of an active paintball site. An apparatus is suggested to evaluate paintball barriernetting in a laboratory. On site testing does not require such an apparatus.1.2 This standard is designed to be used in conjunction with Guide F2184.1.3 The va

Significance and Use4.1 This method is performed to evaluate if paintball barrier netting will prevent an intact paintball or shell fr

18、agments exceeding3 by 5 mm (0.118 by 0.197 in.) from passing through the netting.4.2 This test method provides accurate results about the current effectiveness of the test specimen when field-tested in anexisting installation. Laboratory results are particularly useful for testing the relative effec

19、tiveness of multiple test specimens.4.3 The results stemming from the use of this test method may be used to evaluate the effectiveness of paintball barrier nettingrepresented by the test specimen for use in delineating “goggles-on” areas found at paintball playing fields.4.4 The base procedure outl

20、ined below is applicable to “field-testing.” Additional requirements for “laboratory” testing arenoted.5. Interferences5.1 Laboratory testing does not account for variations that can be found in field tests. These variations include and are notlimited to temperature, UV exposure, wind direction, pre

21、cipitation, and method of installation.5.1.1 This test method is also useful to evaluate the relative performance of one test specimen to another, particularly in thelaboratory.6. Apparatus6.1 Paintball Marker or Markers, of various calibers, capable of discharging paintballs horizontally at a speed

22、 of 94.5 6 6 m/s(310 6 20 ft/s) and conforming to Specification F2272.6.2 Paintballs, of the required calibers, per Specification F1979.6.3 Equipment employed to measure the speed of the test paintball shall be used in accordance with the manufacturersinstructions to measure the velocity of paintbal

23、ls and shall be accurate to within 60.5 m/s (61.6 ft/s) muzzle velocity.6.4 An appropriate backstop placed 30.5 6 2.5 cm (12 6 1 in.) directly behind and parallel to the test specimen. The backstopshall be a minimum of 244 6 5 cm (96 6 2 in.) high and 122 6 5 cm (48 6 2 in.). The backstop shall be a

24、 hard, smooth surfacethat can withstand the impact of a paintball and can be readily cleaned (see Fig. 1).6.5 If testing in a laboratory, the following apparatus shall be used:6.5.1 Paintball Barrier Netting Rack, see Figs. 2 and 3. This rack is capable of holding the 244 6 5 cm (96 6 2 in.) testspe

25、cimen off the floor and providing vertical support 122 6 1 cm (48 6 0.5 in.) apart at the center of the test specimen (see Figs.2 and 3). The bottom crossbar must have a minimum length of 2.74 m (108 in.) and a weight of 5.6 6 0.1 kg (12.3 6 0.2 lb).FIG. 1 Testing Apparatus LayoutF2278 1927. Hazards

Test Specimen8.1 The test specimen shall consist of paintball barrier netting installed in actual use condi

27、tions, or8.2 For laboratory test only:8.2.1 The top of the test specimen is draped over the top crossbar and fastened to itself with tie-wraps spaced 15.2 6 1 cm (66 0.5 in.) apart. The tie-wraps must encircle the top crossbar.8.2.2 The bottom of the test specimen is draped over the bottom crossbar

28、(on the same side as the top) and fastened to itselfwith tie-wraps spaced 15.2 6 1 cm (6 6 0.5 in.) apart, such that the overall length of the test specimen, including the pipes, is244 6 5 cm (96 6 2 in.). The tie-wraps must encircle the bottom crossbar.8.2.3 The test specimen is suspended on the te

29、st rack with the paintball barrier netting flush, against the test rack and nottouching the floor.8.3 The test specimen shall have a minimum horizontal dimension of 305 6 5 cm (120 6 2 in.) and a minimum verticaldimension of 244 6 5 cm (96 6 2 in.).9. Conditioning9.1 The paintball barrier netting to

30、 be tested will be conditioned for at least 4 h. If tested in a laboratory, the paintball barriernetting will be conditioned at SAT.9.2 All testing shall be done using paintballs manufactured within the previous eight months.9.3 Paintball storage and the non-test handling shall be done at a relative

31、 humidity below 65 % and at SAT.9.4 Paintballs shall be conditioned in their original sealed container for at least 4 h at the humidity and temperature specifiedin 9.1.FIG. 2 Netting Test Rack (Front View)F2278 1939.5 The testing shall be conducted at SAT for laboratory tests. Testing shall be compl

32、eted within 10 min after removal of thepaintball from the sealed container. The paintball container shall be resealed immediately after each paintball is removed.10. Procedure10.1 The paintball marker shall be adjusted so that the velocity of a paintball discharged from the marker will be 94.5 6 6 m

33、/s(310 6 20 ft/s).10.2 The muzzle of the paintball marker shall be placed at a distance of 4.6 m (15 ft) from the test specimen.10.3 The muzzle of the paintball marker shall be placed nominally normal to the test specimen, at a distance of 154 6 15 cm(60 6 6 in.) from the bottom and centered horizon

34、tally to the middle of the test specimen.10.3.1 If an area to be tested is above 154 6 15 cm (60 6 6 in.), the bottom of the test specimen, the muzzle, will be maintainedat 154 6 15 cm (60 6 6 in.) and the marker aimed at the test are, immediately vertical from the nominally normal position.10.4 In

35、a safe manner, discharge ten paintballs that impact the test specimen at a distance of 4.6 m (15 ft) within a 15.4 cm (6in.) diameter circle centered 154 6 15 cm (60 6 6 in.) from the bottom and centered horizontally to the middle of the testspecimen, at 1-s intervals between discharges.10.5 Observe

36、 any material passing through the paintball barrier netting, noting if the netting allows intact paintballs or shellfragments greater than 3 by 5 mm (0.118 by 0.197 in.) to pass through.10.6 Paintball barrier netting that does allow an intact paintball or a shell fragment larger than 3 by 5 mm (0.11

37、8 by 0.197 in.)to pass through during this test procedure will be recorded as failed.10.7 This test is to be completed with the largest and smallest calibers or types of paintball that the subject paintball barriernetting is intended to prevent an intact paintball or shell fragments exceeding 3 by 5

38、 mm (0.118 by 0.197 in.) from passing through.10.8 In laboratory test situations record the date, time, air temperature, atmospheric pressure, relative humidity, and results ofthe test at the time of testing.11.
