Terminology2.1 Definitions:2.1.1 security seala passive, one-time locking device todetect tampering or entry, and may be of substantial construc-tion. Seals require inspection to indicate whether tampering hasoccurred or entry has been attempted.2.1.

4、1.1 barrier type security sealsseals that are con-structed and manufactured of material such as steel or cablewith the intent to delay intrusion, and are generally removedwith quality bolt cutters or cable cutters.2.1.1.2 indicative type security sealsseals that are con-structed and manufactured of

5、material that can easily be brokenby hand or simple snipping tool or shear.3. Significance and Use3.1 This standard is intended to provide information oncurrently available commercial seals as a guide in theirselection for specific applications. This classification is notintended to inhibit innovati

6、on or development of new types ofseals.4. Basis of Classification4.1 Security seals in this standard are classified by theirconfiguration and the material from which they are made.5. Types of Seals5.1 WireWire seals consist of a length of wire secured ina loop by some type of seizing device. Example

7、s of this typeare crimp wire, fold wire, and cup wire.5.2 PadlockThe padlock type of seal consists of a lockingbody with a bail attached.

12、od or heavy gagewire of various diameters, which is inserted through thelocking fixture and twisted around itself by use of a tool.5.8 ScoredThis seal is a metal strip which is scoredperpendicular to the length of the strip. The strip is passedthrough the locking fixture and bent at the score mark.R

13、emoval of the seal requires bending at the score mark whichresults in breakage of the seal.5.9 LabelLabel seals are frangible seals consisting of apaper or plastic backing with adhesive.
