Significance And Use:

1. If a seal can be opened by any means and successfully reapplied without exhibiting signs indicative of prior attack, the integral quality of the seal is in serious question. This guide allows that any particular method of attempted defeat can be employed to defeat a seal, and concentrates not on the effectiveness of the seal to resist that attack, but rather on the nature of the individual seal to inhibit reapplication.

2. This standard presents guidelines for inspection to assist in determining whether an attempt to defeat a security seal, and to possibly reapply the seal, has been made. In all cases, the guidelines are meant to focus attention on signs of attack and reapplication.

Scope:

1 This guide covers procedures for the inspection and evaluation of tampering of security seals.

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.

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.

A security seal is a manufactured product that is used to indicate tampering or unauthorized opening of a container, door, or item. Mechanical security seals and label seals are usually designed for one-time use. All one-time use seals, some reusable and non-reusable barrier seals, and label seals are used for commercial applications. For the purposes of this guide, the term seal will be synonymous with the terms security seal, anti-tamper device, and tamper indicating device.

ROLE OF SEALS

A seal is a closure device that serves as a check against tampering or unauthorized opening. If designed and attached properly, a seal should be severed or mutilated before entry is possible.

Seals designed to delay intrusion are commonly constructed of solid steel or cable.

Seals can provide a psychological deterrent by ensuring that evidence of forced entry or tampering is clearly visible and that the crime can not be subsequently hidden or covered up.

Seals can be used for material control, accountability, and inventory by associating the seal identification number with the contents.

An intact seal applied within the context of a strong seal control program provides for an increased level of fidelity of cargo security. This reduces the number of personnel needed to control secured items and minimizes the potential of exposure to possible hazardous contents.

Seals are intended to be part of an integrated security program. Seals should not be used as stand-alone protection.

WHEN SEALS SHOULD BE USED

When there is a written requirement (see Section 5).

When there is concern about pilferage by in-house personnel or crime by outsiders. If the threat is from outsiders, seals with some level of forced entry protection should be selected.

If a damaged or broken seal can be discovered in a timely manner and appropriate countermeasures can be implemented to prevent further criminal activity.

As part of a comprehensive security program.

Seals should be used in conjunction with a seal control program that is part of an integrated security system. Security systems can consist of multiple components (intrusion detection, closed circuit television, access control, security personnel, lighting, barriers, etc.). Integration produces a system that will provide a high level of confidence and protection in depth (multiple layers of protection). If a security system component fails to function in an integrated system, the other components and layers will continue to provide some level of protection until the failed component is repaired or replaced. Seals and a seal control program are examples of components that can be important to an integrated security system by providing additional layers of protection.
