1.1 This test method provides a range of impact speeds to be used with a 22 250-N [5000 lb] surrogate test vehicle. This test method establishes a range for penetration performance ratings. End users will be responsible for identifying the appropriate vehicle impact speed and penetration performance ratings in this test method that satisfies their specific needs.

1.2 Units-The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the 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.
