ASTM F 1157 : 1990 : R2001

1.1 This practice presents methods for testing the physical properties of security seals. Where appropriate, the various tests include particular apparatus or procedural specifications required for different types of security seals.

1.2 This practice will serve as a basis for comparing the response of various security seals under different modes of attack. The security seal to be evaluated shall first be placed in an appropriate classification, and then tested in the manner designated as most suitable for that class of seal, in accordance with Classification F832.

Note 1--See Guide F1158 for procedures on the inspection and evaluation of tampering of security seals.

1.3 A security seal is a device intended to detect tampering or entry. Single use locking devices are to be evaluated under this specification. Therefore, the following procedures are to reflect the relative performance of security seals when subject to various physical attacks.

1.4 This practice is not intended to be fully comprehensive, since certain types of security seals, such as labels, are not addressed. Further, it is the responsibility of users of this practice to interpret their specific security needs concerning the application of seals, and to determine the grade of seal appropriate for their particular application. ASTM assumes no responsibility for losses occurring as a result of a defeated seal whether the defeat is apparent or the seal is not suited for its application.

1.5 The values as stated in inch-pound units are to be regarded as the standard. The values in parentheses are given for information only.

1.6 The following safety hazards caveat pertains only to the test procedures portion, Section 6, of this practice. 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 and health practices and determine the applicability of regulatory limitations prior to use.
