1、Designation: F832 90 (Reapproved 2016)Standard Classification forSecurity Seals1This standard is issued under the fixed designation F832; the number immediately following the designation indicates the year of originaladoption or, in the case of revision, the year of last revision. A number in parent

2、heses indicates the year of last reapproval. A superscriptepsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This classification covers categories of commerciallyavailable security seals. Special-purpose seals, such as fiberoptic and sophisticated electronic s

3、eals, are not covered by thisclassification.2. 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.2.1.1.1

4、 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 mat

5、erial 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 innovation

6、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. Examples o

7、f this typeare crimp wire, fold wire, and cup wire.5.2 PadlockThe padlock type of seal consists of a lockingbody with a bail attached. Examples of this type of seal are thewire shackle padlock (metal or plastic body), plastic padlock,and keyless padlock.5.3 StrapThe strap seal is a metal or plastic

8、strap which issecured to form a loop by inserting one end into or through alocking mechanism on the other end. Examples of this type arethe box and ball end seal.5.4 CableThe cable seal consists of a cable and a lockingmechanism. On a one-piece seal, the locking or seizingmechanism is permanently at

9、tached to one end of the cable. Atwo-piece cable seal has a separate locking mechanism whichslips onto the cable or prefabricated end.5.5 BoltThe bolt seal is a metal rod, threaded orunthreaded, with a formed head, and is secured with a separatelocking mechanism. Threaded bolts are usually bent afte

10、rinstallation to upset the threads and prevent undetected re-moval of the locking mechanism.5.6 Cinch or Pull-UpThe cinch or pull-up type is anindicative seal. It consists of a thin strip of material, serrated ornonserrated, with a locking mechanism attached to one end.The free end is pulled through

11、 a hole in the locking mechanismand drawn up to the necessary tightness. Cinch or pull-up typeseals may have multiple lock positions. These seals aregenerally made of synthetics such as nylon or plastic andshould not be compared to simple electrical ties.5.7 TwistTwist seals are made of steel rod or

12、 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.Remova

13、l 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. The combination ofbacking and adhesive are chosen to cause the seal to tear whenremoval is attempted.6. Keywords6.1 ba
