ASTM F967-03(R2018) pdf free download.Standard Practice for Security Engineering Symbols
1. Scope
1.1 This practice utilizes symbols to depict security systems and equipment requirements for architectural or engineering drawings that are produced either manually or by computer aided design (CAD). The symbols depicted include some symbols that have already been somewhat universally accepted or that have already been adopted by a standards-writing body, such as by the National Fire Protection Association. 1.2 It is not proposed that all of the symbols need to be utilized since the level of detail required for drawings is likely to vary. Generic symbols of a class of security device may be sufficient in some instances. Moreover, the need to provide a measure of security in the actual drawing may also suggest a need to utilize a generic symbol rather than to depict the exact device being installed. 1.3 In the event that a greater level of detail is required, it is possible to combine many of the symbols to create new symbols that achieve the desired level. While some combina- tions of symbols are shown, it would be impractical to attempt to depict every conceivable combination of symbols. It is also the intent of this practice that the symbols be capable of being continuously expanded and modified as the industry state ofthe art changes or as emphasis varies. For example, little attention is given to document security in the security symbols since such requirements are not generally fully met during construc- tion periods but are rather developed and provided for subse- quently. Since much of this equipment is not installed but is “placed,” such as furniture, there is only one symbol proposed (for example, for document shredders).1.4 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 appro- priate safety, health, and environmental practices and deter- mine the applicability ofregulatory limitations prior to use. 1.5 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
X1.1 This commentary provides a brief history and ratio- nale for a significant revision to this practice. This revision expanded the focus and intent of this standard beyond a practice for manual drafting to encompass computer aided design (CAD). This commentary also provides a technical source of reference for additional information related to, but beyond the scope of, this practice. X1.2 The original practice was developed with the intent of providing consistency in the engineering symbols used for depiction of security system layout and design on architectural and engineering drawings, as detailed in the scope. At the time of conception, manual generation of these drawings was the most commonly used method, and the community of large system designers that would have use for such standard symbols was relatively small. X1.3 Over time, advances in technology enabled effective generation of architectural and engineering drawings through CAD, as well as ancillary uses and linkages for the digitally stored symbols. As this capability and the security industry grew, numerous sets of new symbols were found on CAD drawings with considerable inconsistency.
