This test method is used for determining the force required to cause a hypodermic needle to penetrate through protective clothing material. It defines three common hypodermic needles - 21-, 25-, 28- gauge needles - to evaluate puncture resistance of protective clothing. This test method does not attempt to simulate all use conditions. A number of variables which impact puncture resistance, such as stiffness of backing materials, presence of lubricants, and tension on the specimen, are not addressed by this test method.
This test method evaluates puncture resistance of protective clothing materials which may include: plastics or elastomeric films, coated fabrics, flexible materials, laminates, leathers or textile materials.
This test method uses hypodermic needles with specified dimensions as puncture probes.
This test method evaluates puncture resistance of protective clothing materials, perpendicular to the material’s surface and with no supporting structure under/behind the material specimen.
Evaluation of puncture resistance for snag-type puncture should be performed in accordance with Test Method D2582.
Evaluation of puncture resistance for non-cutting puncture should be performed in accordance with Test Method F1342.
