Significance and Use4.1 U.S. Department of Defense and

16、U.S. Department of Justice standards for assessing the performance of ballistic-resistantpersonal protective equipment require the use of properly configured indoor test ranges. This specification is one of severalstandards that will help to ensure that testing results between test ranges are compar

17、able.4.2 This specification may be used by private-sector and government laboratories, manufacturers, research and developmentorganizations, and others assessing the ballistic resistance of personal protective equipment.4.3 It is intended that this specification be referenced by other standards, spe

18、cifications, or test methods, or combinationsthereof.5. Minimum Room Dimensions5.1 The test range dimensions should be sufficient to accommodate the required equipment and spacing between that equipmentand the room walls and ceiling so personnel can safely perform testing without obstruction.6. Rang

19、e Environmental Conditions6.1 The relative humidity shall be 50 6 20 %.6.2 The controlled ambient temperature shall be 68 6 10F (20 6 5.5C).6.3 General lighting on the range should provide adequate light levels to enable personnel to perform assigned duties. Locallighting to supplement general light

20、ing, if needed, should be available to provide better visibility for tasks associated withmeasurements and instrument readings.NOTE 1Local lighting may be a flashlight, headlamp, or other light source that does not emit enough heat to affect the test results.7. Projectile Firing System7.1 The projec

21、tile firing system shall be one of the following:7.1.1 Receiver and test barrel.7.1.2 Firearm.NOTE 2Use of a firearm is not the preferred method.7.2 All components of the projectile firing system shall be mounted.NOTE 3The intent of mounting the projectile firing system is to achieve accurate and re

22、peatable performance.8. Measurement Systems8.1 Projectile Velocity Measurement System:8.1.1 The system shall maintain position and alignment during testing.8.1.2 The system shall be appropriate for the projectile and the velocities being measured.8.1.3 An independent method for verifying the accurac

23、y of the system shall be available.8.1.4 The projectile velocity should be determined using at least two electronically independent sets of instrumentation. If twoelectronically independent sets of instrumentation are not used, the reason and the type of instrumentation used shall bedocumented.8.1.4

24、.1 For each projectile firing, the two independent sets of instrumentation shall provide individual velocity measurementswithin 10 ft/s (3 m/s) of each other, with the following considerations.(1) If the screen pairs do not agree within 10 ft/s (3 m/s) and either screen pair yields a reading that is

25、 not within 75 % of theintended test threat velocity, that value should be discarded, and the other reading shall be recorded as the velocity measurement.All occurrences of this condition shall be documented.(2) If the screen pairs do not agree within 10 ft/s (3 m/s) and both screen pairs yield a re

26、ading that is within 75 % of the intendedtest threat velocity, the test result is considered invalid, and the test shall be redone. All occurrences of this condition shall bedocumented.(3) If there is reasonable doubt that the screen pairs are reading correctly, the test result may be considered inv

27、alid, and thetest shall be redone. All occurrences of this condition shall be documented.NOTE 4Appendix X1 provides examples to aid in understanding these considerations.NOTE 5This standard does not address velocity loss (that is, drag) from the measurement location to the test item. Other standards

28、, specifications,or test methods can address velocity loss.8.1.5 Undesirable influences on the velocity measurement system shall be mitigated.E3062 1612NOTE 6Undesirable influences include, but are not necessarily limited to, shock waves, sound waves, light, ejected propellant, sabots, and otherdebr

29、is.8.2 Projectile Yaw Measurement System:8.2.1 The test laboratory shall provide a method for verifying yaw.NOTE 7Yaw requirements (for example, maximum allowable yaw) and details necessary for making yaw measurements (for example, location ofyaw measurement) are specified in other standards, specif

30、ications, or test methods, or combinations thereof.9. Spacing and Set Up of Test Equipment9.1 The test equipment shall be set up as shown in Fig. 1 with spacing and additional requirements as described in Table 1 andthe remainder of this section.9.1.1 The test equipment shall be set up as though the

31、 shot were to be taken at an angle of incidence of 0; the test equipmentshall not be moved, except as it pertains to translating for aiming and rotating to accommodate obliquity or angle of incidencerequirements.9.2 The distance from muzzle to test item reference plane (D1 in Fig. 1) may be adjusted

32、 to minimize yaw or blast effects. Thereason for the adjustment and the distance used shall be documented. The distance from the location of velocity measurement tothe test item reference plane (D2 in Fig. 1) shall not be adjusted.NOTE 8The test item reference plane will be specified in other standa

33、rds, specifications, or test methods because the test items reference plane differsdepending on the test item.9.3 If radar, high-speed video, or X-ray is used for velocity measurement, the velocity reported shall be either the velocitymeasured at the location given in Table 1 or the velocity measure

34、d at the test item as specified in other standards, specifications,or test methods.9.4 If light screens are used for velocity measurement, the requirements below shall be met.9.4.1 The light screens shall be positioned as shown in Fig. 2.9.4.2 The inner screens shall be paired together, and the oute

35、r screens shall be paired together.9.4.3 The light screen pairs shall be parallel to each other and perpendicular to the projectile firing system barrel.9.4.4 The distance from the last light screen to the test item reference plane shall be no greater than 5 ft (1.5 m).9.4.5 The light screens shall

36、be fastened together to prevent inadvertent changes in spacing.NOTE 9The spacing between the light screens may be adjusted to meet velocity measurement requirements.10. Test Item Mounting System10.1 The test stand shall maintain position during the test event.NOTE 10Examples include, but are not lim

37、ited to, test stands that are affixed to the building structure or those that have sufficient mass.NOTE 11This specification does not describe any specific fixture, backing assembly, or witness panel for the test item.FIG. 1 Test Range Setup and Relative PositioningE3062 161310.2 The test item mount

38、ing system shall permit the test item and any backing material or witness panel to be shifted verticallyand laterally to allow ballistic impacts at various locations on the test item.10.3 The test item mounting system shall permit the test item and any backing material or witness panel to be rotated

39、 to allowfor shots impacting the test item at angles other than 0.10.4 A backstop or bullet trap should be positioned at a distance behind the test item location.11.

43、ION RELATED TO THE CONSIDERATIONS IN 8.1.4.1X1.1 The exception allowed in 8.1.4.1 comes into play when one of the two light screen pairs does not yield a correct result (forexample, false trigger, failure to trigger, or pre-trigger). This occurrence is more likely to happen for some test threats: (1

44、) Rifle,handgun: This is a rare occurrence. (2) Fragments, shotgun: This can occur more often.X1.2 75 % of the intended velocity was set as the decision point, and the following examples are provided to aid understanding.The examples use an intended velocity of 1000 ft/s: Example 1: Screen pair 1 =

45、1000 ft/s, and Screen pair 2 = 249 ft/s: This shot is considered to be valid; the screen pair 1 result is accepted and documented; thescreen pair 2 result is discarded. Example 2: Screen pair 1 = 1000 ft/s, and Screen pair 2 = 250 ft/s: This shot is considered to be invalid; both screen pair results

46、 are rejected and documented. Example 3: Screen pair 1 = 1000 ft/s, and Screen pair 2 = 251 ft/s: This shot is considered to be invalid; both screen pair results are rejected and documented.ASTM International takes no position respecting the validity of any patent rights asserted in connection with
