1.1This 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 to satisfy their specific needs.
1.1.1In addition, end users may assign certification ratings for vehicle protective devices based on the test methodologies described herein. Test parameters are standardized to arrive at a common vehicle weight, enhance test realism and replication, and produce uniform rating designations.
1.2Units—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.
1.3This 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 and health practices and determine the applicability of regulatory limitations prior to use.
