摘要：

In Canada, during impaired driving investigations, peace officers can utilize an Approved Screening Device (ASD) as a tool to ascertain the presence of alcohol in a person's body. Reliability of breath test results obtained on an ASD require that quality assurance procedures are followed, including a regular calibration check of the device at least once every 31 days. The purpose of this study was to evaluate the calibration stability of the Alco-Sensor FST to ensure that a monthly calibration check schedule is scientifically appropriate. Calibration checks were conducted on five Alco-Sensor FSTs over a period of seven weeks. Over this period of time, all ASDs provided results within the acceptable range of 95 to 105 milligrams of alcohol in 100 millilitres of blood (mg%) when challenged with an alcohol standard with a target result of 100 mg%. None of the five ASDs required recalibration within the 7 week period. The results of this study demonstrate that the calibration of the Alco-Sensor FST is stable beyond the recommended calibration check interval.
