ASTM F2656/F2656M-15

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

INTRODUCTION
Original perimeter barrier test methods were first published in 1985 by the Bureau of Diplomatic
Security to assess the crash performance of perimeter barriers and gates. Since that time, the frequency
and scale of attacks using vehicles with or without an explosive payload have increased both
internationally and domestically. Therefore, there is a need to address a broad spectrum of possible
incident conditions such as credible threat vehicle types for the locale, attack velocities of the different
vehicles, and different acceptable penetration limitations. Also, there are different evaluation criteria
for different agencies that fulfill their unique access control operations, aesthetics, and other
organizational requirements. This test method is intended was originally developed to expand the
currentprevious Department of State, Bureau of Diplomatic Security’s crash testing standard to meet
the broader needs of multiple organizations responsible for the protection of U.S. assets domestically
and abroad.
Published test standards for vehicle perimeter security devices have previously been maintained by
the U.S. State Department, Bureau of Diplomatic Security. The Specification for Vehicle Crash Test
of Perimeter Barriers and Gates was first published in 1985 as SD-STD-02.01. In that standard, the test
vehicle was specified as a medium-duty truck weighing 6800 kg (15[15 000 lb).lb]. The payload was
to be securely attached to the frame and nominal impact velocities were 50 km/h (30 mph), 65 km/h
(40 mph), 50, 65, and 80 km/h (50 mph). [30, 40, and 50 mph]. Penetration limits were 1 m (3 ft), 6
m (20 ft), 1, 6, and 15 m (50 ft) and [3, 20, and 50 ft] and were measured from the attack face of the
perimeter security device to the final resting position of the front of the frame rails of the test vehicle.
In 2003, the U.S. State Department, Bureau of Diplomatic Security issued an updated standard
(SD-STD-02.01, Revision A) for the testing of perimeter barriers. This update was done for several
reasons. The foremost reason for change was limited setback distances precluded the use of any
devices at their facilities or compounds that did not meet the highest test level, that is, those allowing
more than 1-m (3-ft)[3-ft] penetration distance. Therefore, the revised standard only uses a 1-m
(3-ft)[3-ft] penetration distance. Secondly, the method of rigid attachment of the ballast to the test
vehicle was not simulating likely payload configurations and was altering the structural integrity of the
test vehicle. Consequently, the updated standard requires a payload consisting of 208-L (55-gal)[55-
gal] steel drums strapped together that have been filled with soil. This assembly is then strapped to the
vehicle load platform. The third reason for change was based on the observation that the cargo bed of
trucks could effectively penetrate certain types of barriers. Accordingly, the penetration distance is
now measured from the inside face or non-impact surface of the barrier to the front of the cargo bed
when the vehicle has reached its final position. Lastly, it was determined that the trucks used different
platforms within a given class affecting result consistency. The revised test standard now requires
required the use of very specific diesel-powered medium-duty trucks.
In 2007, ASTM first published Test Method F2656 for Vehicle Crash Testing of Perimeter Barriers.
It included the same test vehicle as specified in the 2003 SD-STD-02.01, Revision A, but additional
