【国外标准】 Standard Practice for Classifying the Relative Performance of the Physical Properties of Security Seals

This practice covers methods for testing the physical properties of mechanical (passive) security seals. Where appropriate, the various tests include particular apparatus or procedural specifications required for different types of security seals. A security seal shall be evaluated in accordance with its classification into one of five general groups and its performance in the following six tests: pull (tensile) shear, bending, impact, low temperature impact, and high temperature pull (tensile). A security seal shall receive a grade designation based upon its measured performance in each of the required tests. The seals shall be classified according to groups: Group 1; Group 2; Group 3; Group 4; and Group 5. Pull test, shear test, bending test, impact test, and extreme temperature tests shall be performed to conform with the specified requirements.1.1 This practice covers methods for testing the physical properties of mechanical (passive) security seals. Where appropriate, the various tests include particular apparatus or procedural specifications required for different types of security seals. This practice does not address adhesive (tape or label style) or electronic types of security seals.1.2 This practice will serve as a basis for comparing the response of various security seals under different simulated modes of attack. The security seal to be evaluated shall first be classified into established groupings, and then tested in the manner designated as most suitable for that class of seal, in accordance with Classification F832.1.3 A mechanical security seal is a single use, passive device intended to detect tampering or entry into the sealed item. Removal of the security seal requires permanent and irreversible damage to the seal. The following procedures reflect the relative performance of security seals when subject to various destructive physical attacks. These tests simulate known and likely security seal implementation and attack methods.1.4 Security seals often contain unique identification markings for authentication purposes to discourage duplication and to prevent reapplication. This practice does not address unique identifiers or vulnerabilities of security seals.NOTE 1: See Guide F1158 for procedures on the inspection and evaluation of tampering of security seals. See also Guide F946.1.5 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.1.6 The values as stated in inch-pound units are to be regarded as the standard. The values in parentheses are given for information only.1.7 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.8 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.
