ASTM F1158-94

Standard Guide for Inspection and Evaluation of Tampering of Security Seals

SCOPE
1.1 This guide covers procedures for the inspection and evaluation of tampering of security seals.
1.2 A security seal is a device intended to detect tampering or entry. Evaluate only single use locking devices under this guide. The following procedures shall serve as guidelines for detecting attempts at defeat and reapplication of a security seal.
1.3 This guide is not intended to be fully comprehensive; certain types of security seals, such as labels, have not been addressed to date. Further, it is the responsibility of users of this guide to interpret their specific security needs concerning the use 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.
