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 abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
Significance and Use
5.1 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.
5.1.1 This test method uses hypodermic needles with specified dimensions as puncture probes.
5.1.2 This test method evaluates needle puncture resistance of protective clothing materials, perpendicular to the material’s surface and with no supporting structure under/behind the material specimen.
5.1.3 Evaluation of puncture resistance for snag-type puncture should be performed in accordance with Test Method .
5.1.4 Evaluation of puncture resistance for non-cutting puncture should be performed in accordance with Test Method .
1.1 This test method is used to determine the force required to cause a sharp-edged hypodermic needle to penetrate through protective clothing material. The standard describes three needles that may be used: 21-, 25-, or 28-gauge needles.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
