1.1 General:

1.1.1 This specification presents baseline performance requirements and additional optional capabilities for stationary point chemical vapor detectors (SPCVD) designed for continuous, 24 hours a day 7 days a week, monitoring of public, non-industrial facilities. This specification is one of several that describe chemical vapor detectors (for example, handheld and stationary) and chemical detection capabilities including: chemical vapor hazard detection, identification, and quantification. An SPCVD is capable of detecting and alarming when exposed to chemical vapors that pose a risk as defined by the Acute Exposure Guideline Levels for Selected Airborne Chemicals (AEGL). For example, chemical vapors of interest for homeland security applications, see Appendix X1. The SPCVD should not alarm to background chemical vapors and should provide low false positive alarm rates and no false negatives. Procurement agents and end users must identify the specific chemicals of interest and environmental requirements for the given facility.

1.1.1.1 An SPCVD samples air from immediate surroundings and is comprised of one or more detectors using one or more chemical detection technologies. An SPCVD also includes air sampling system(s), power system(s), computer(s), data storage, data network communication interface(s), and an enclosure, see Fig. 1

Vapor Detector (SPCVD). The SPCVD is a unit which samples air from
immediate surroundings and is comprised of one or more detectors using
one or more chemical detection technologies. An SPCVD also includes
air sampling system(s), power system(s), computer(s), data storage,
data network communication interface(s), and an enclosure.

An SPCVD also includes air sampling system(s), power system(s), computer(s), data storage, data network communication interface(s), and an enclosure.
. An SPCVD may be combined with other SPCVDs, other chemical, biological, radiological, nuclear, and explosive (CBRNE) detectors, and other monitoring devices such as video. A remote command center may monitor and control these devices and communicate information to the responsible authorities and responders, as depicted in Fig. 2.

1.1.2 This specification provides the SPCVD baseline requirements, including performance, system, environmental, and documentation requirements. This specification provides SPCVD designers, manufacturers, integrators, procurement personnel, end users/practitioners, and responsible authorities a common set of parameters to match capabilities and user needs.

1.1.3 This specification is not meant to provide for all uses. Manufacturers, purchasers, and end users will need to determine specific requirements based on the installation location and environment.

1.2 SPCVD Chemical Detection Capabilities—Manufacturers document and verify, through testing, the chemical detection capabilities of the SPCVD. Test methods for assessing chemical detection capabilities are available from the Department of Homeland Security and the Department of Defense and are listed in Appendix X2.

1.3 SPCVD System and Environmental Properties—Manufacturers document and verify, through testing, the system and environmental properties of the SPCVD. Example test methods for assessing the system and environmental properties are listed in Appendix X3.

1.4 Units—The values stated in SI units are to be regarded as standard. Vapor concentrations of the hazardous materials are presented in parts per million (ppm) as used in Acute Exposure Guideline Levels for Selected Airborne Chemicals, Vols 1-9 (see 2.2) and in mg/m3.

1.5 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 and health practices and determine the applicability of regulatory limitations prior to use.
