4.1 This practice sets forth the minimum requirements for calibration and functionality checks when conducting PDD examinations and related activities. For additional information see Practice E1954 and Guide E2000.

1.1 This practice provides guidelines for calibration and instrumentation (both analog and computerized systems) actively used in the psychophysiological detection of deception (verification of truth). As a minimum, such instrumentation shall simultaneously record an individual’s respiratory, exosomatic electrodermal, and cardiovascular activity.

1.2 Analog polygraphs shall be calibrated by the psychophysiological detection of deception (PDD) examiner, manufacturer, or factory-authorized individual.

1.3 Computerized instrumentation shall be calibrated by the manufacturer or factory-authorized individual.

1.4 The PDD examiner or factory-authorized individual shall perform functionality checks to ensure instrumentation is operating properly.

1.5 This practice does not prohibit additional components which may be offered as supplemental measurements of physiological change. Additional recording components (such as movement sensors) may be used in addition to, but not replace, the required minimum components and these additional components shall meet the manufacturer’s specifications for calibration.

1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
