United States14.2 This specification may be used by private-sector andgovernment laboratories, manufacturers, research and develop-ment organizations, and others assessing the ballistic resistanceof personal protective equipment.4.3 It is inten
16、ded that this specification be referenced byother standards, specifications, or test methods, or combina-tions thereof.5. Minimum Room Dimensions5.1 The test range dimensions should be sufficient to ac-commodate the required equipment and spacing between thatequipment and the room walls and ceiling
17、so personnel cansafely perform testing without obstruction.6. Range 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 adequatelight levels to enable personnel to pe
18、rform assigned duties.Local lighting to supplement general lighting, if needed, shouldbe available to provide better visibility for tasks associatedwith measurements and instrument readings.NOTE 1Local lighting may be a flashlight, headlamp, or other lightsource that does not emit enough heat to aff
19、ect the test results.7. Projectile Firing System7.1 The projectile firing system shall be one of the follow-ing: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 bemounted.NOTE 3The intent of mount
20、ing the projectile firing system is toachieve accurate and repeatable performance.8. Measurement Systems8.1 Projectile Velocity Measurement System:8.1.1 The system shall maintain position and alignmentduring testing.8.1.2 The system shall be appropriate for the projectile andthe velocities being mea
21、sured.8.1.3 An independent method for verifying the accuracy ofthe system shall be available.8.1.4 The projectile velocity should be determined using atleast two electronically independent sets of instrumentation. Iftwo electronically independent sets of instrumentation are notused, the reason and t
22、he type of instrumentation used shall bedocumented.8.1.4.1 For each projectile firing, the two independent setsof instrumentation shall provide individual velocity measure-ments within 10 ft/s (3 m/s) of each other, with the followingconsiderations.(1) If the screen pairs do not agree within 10 ft/s
23、 (3 m/s)and either screen pair yields a reading that is not within 75 %of the intended test threat velocity, that value should bediscarded, and the other reading shall be recorded as thevelocity measurement. All occurrences of this condition shallbe documented.(2) If the screen pairs do not agree wi
24、thin 10 ft/s (3 m/s)and both screen pairs yield a reading that is within 75 % of theintended test threat velocity, the test result is consideredinvalid, and the test shall be redone. All occurrences of thiscondition shall be documented.(3) If there is reasonable doubt that the screen pairs arereadin
25、g correctly, the test result may be considered invalid, andthe test shall be redone. All occurrences of this condition shallbe documented.NOTE 4Appendix X1 provides examples to aid in understanding theseconsiderations.NOTE 5This standard does not address velocity loss (that is, drag)from the measure
26、ment location to the test item. Other standards,specifications, or test methods can address velocity loss.8.1.5 Undesirable influences on the velocity measurementsystem shall be mitigated.NOTE 6Undesirable influences include, but are not necessarily limitedto, shock waves, sound waves, light, ejecte
27、d propellant, sabots, and otherdebris.8.2 Projectile Yaw Measurement System:8.2.1 The test laboratory shall provide a method for verify-ing yaw.NOTE 7Yaw requirements (for example, maximum allowable yaw)and details necessary for making yaw measurements (for example,location of yaw measurement) are s
28、pecified in other standards,specifications, 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. 1with spacing and additional requirements as described in Table1 and the remainder of this section.9.1.1 The test equipm
29、ent shall be set up as though the shotwere to be taken at an angle of incidence of 0; the testequipment shall not be moved, except as it pertains totranslating for aiming and rotating to accommodate obliquityor angle of incidence requirements.9.2 The distance from muzzle to test item reference plane
30、(D1 in Fig. 1) may be adjusted to minimize yaw or blast effects.The reason for the adjustment and the distance used shall bedocumented. The distance from the location of velocity mea-surement to the test item reference plane (D2 in Fig. 1) shallnot be adjusted.NOTE 8The test item reference plane wil
31、l be specified in otherstandards, specifications, or test methods because the test items referenceplane differs depending on the test item.9.3 If radar, high-speed video, or X-ray is used for velocitymeasurement, the velocity reported shall be either the velocitymeasured at the location given in Tab
32、le 1 or the velocitymeasured at the test item as specified in other standards,specifications, or test methods.9.4 If light screens are used for velocity measurement, therequirements below shall be met.E3062 1629.4.1 The light screens shall be positioned as shown in Fig.2.9.4.2 The inner screens shal
33、l be paired together, and theouter screens shall be paired together.9.4.3 The light screen pairs shall be parallel to each otherand perpendicular to the projectile firing system barrel.9.4.4 The distance from the last light screen to the test itemreference plane shall be no greater than 5 ft (1.5 m)
34、.9.4.5 The light screens shall be fastened together to preventinadvertent changes in spacing.NOTE 9The spacing between the light screens may be adjusted tomeet velocity measurement requirements.10. Test Item Mounting System10.1 The test stand shall maintain position during the testevent.NOTE 10Examp
35、les include, but are not limited to, test stands that areaffixed 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.10.2 The test item mounting system shall permit the test
36、item and any backing material or witness panel to be shiftedvertically and laterally to allow ballistic impacts at variouslocations on the test item.10.3 The test item mounting system shall permit the testitem and any backing material or witness panel to be rotated toallow for shots impacting the te
37、st item at angles other than 0.10.4 A backstop or bullet trap should be positioned at adistance behind the test item location.11.

HELPFUL INFORMATION RELATED TO THE CONSIDERATIONS IN 8.1.4.1X1.1 Th
41、e exception allowed in 8.1.4.1 comes into playwhen one of the two light screen pairs does not yield a correctresult (for example, false trigger, failure to trigger, or pre-trigger). This occurrence is more likely to happen for some testthreats: (1) Rifle, handgun: This is a rare occurrence. (2)Fragm
42、ents, shotgun: This can occur more often.X1.2 75 % of the intended velocity was set as the decisionpoint, and the following examples are provided to aid under-standing. The examples use an intended velocity of 1000 ft/s: Example 1: Screen pair 1 = 1000 ft/s, and Screen pair 2 = 249 ft/s: This shotis
43、 considered to be valid; the screen pair 1 result is accepted and documented;the screen pair 2 result is discarded. Example 2: Screen pair 1 = 1000 ft/s, and Screen pair 2 = 250 ft/s: This shotis considered to be invalid; both screen pair results are rejected anddocumented. Example 3: Screen pair 1
44、= 1000 ft/s, and Screen pair 2 = 251 ft/s: This shotis considered to be invalid; both screen pair results are rejected anddocumented.ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentionedin this standard.
