OAR 257-100-0055
Device Routine Maintenance and Calibration

(1) Prior to calibration the device and camera must be inspected at the vehicle for evidence of tampering or camera obstruction. Calibration ensures the device remains capable of accurately analyzing a breath sample. During calibration all the data collected on the device either from installation or last calibration of the device is uploaded to the manufacturer or manufacturer’s representative’s server or network. The calibration process and vehicle inspection must be performed at intervals not to exceed 67 days, calculated from the installation date or last calibration date. The device must give the individual at least a 7 day notification before calibration is required. The device must enter a lockout if the device has not been checked for calibration accuracy within 67 days after the last calibration.
(2) The device will enter into lockout if service is not performed within 7 days of a scheduled service date or violation as defined in ORS 813.599 (Definitions).
(3) If a device enters a lockout, a remote lockout override may be provided only by the manufacturer or manufacturer’s representative.
(4) A remote lockout override may not be performed unless OSP has approved the manufacturer or manufacturer’s representative’s lockout override procedure for the device model, in accordance with this rule.
(5) OSP shall approve the remote lockout override procedure for a device model if the device meets the following requirements:
(a) A remote lockout override may be performed on a device by entering a unique lockout override code into the device or by a manufacturer controlled remote connection procedure used to override a lockout condition.
(b) A remote lockout override may remain valid only for a period of 12 hours, after which the device must revert to a lockout.
(c) After a manufacturer, manufacturer’s representative, or individual performs a remote lockout override, the device must continue to operate as required in these rules OAR 257-100-0010 (Ignition Interlock Device Standards and Requirements), 257-100-0055 (Device Routine Maintenance and Calibration), and ORS 813.599 (Definitions).
(d) Each remote lockout override must be uniquely identified and recorded in the device’s data storage system.
(6) A device must be calibrated for accuracy by using a wet bath simulator or dry gas alcohol standard with an alcohol reference value between 0.020 grams per two hundred-ten liters (g/210L) and 0.050 g/210L. The calibration process must consist of the following procedures:
(a) An “as found” check to introduce the sample into the device without adjustment for accuracy. The test must be conducted prior to any adjustment for accuracy and the results must be recorded on the data logger. If the results of the “as found” check are within plus or minus (+/-) 0.005 g/210L of the adjusted reference value, then no adjustment is necessary.
(b) If the results of the “as found” check are not within +/- 0.005 g/210L of the adjusted reference value, the device shall be adjusted to restore accuracy before the device may be placed into service.
(7) A service center must remove from service any device that does not pass calibration after two adjustments. The manufacturer’s representative must maintain a record of the serial number of the device for proper record maintenance. A device removed from service for failing calibration may be returned to service only if the device is repaired by the manufacturer to meet the standards described in OAR 257-100-0010 (Ignition Interlock Device Standards and Requirements) and 257-100-0055 (Device Routine Maintenance and Calibration). All repairs to a device must be documented and kept in the manufacturer’s representative’s records.
(8) Wet bath simulators must be:
(a) Listed, or approved to be listed, on the 2012 NHTSA Conforming Products List of Calibrating Units for Breath Alcohol Testers. This list is available from OSP;
(b) Clean, with no noticeable stains, heavy soil build up, or algae.
(c) Properly calibrated within the last 12 months.
(d) Stored at room temperature and not subjected to temperatures greater than 30°Celsius (86°Fahrenheit) or less than 0°Celsius (32°Fahrenheit).
(e) Used to calibrate devices only when the device has reached the proper operating temperature of 34°Celsius +-.2 degrees (93.2° Fahrenheit).
(f) Properly sealed:
(A) Rubber seals are not cracked or out of tolerance; and
(B) Glass is not chipped.
(g) Used with tubing that is:
(A) Compatible with alcohol testing (Tygon or equivalent);
(B) No more than 6 inches long (outlet tube) to prevent condensation; and
(C) Sealed when not in use.
(4) Wet Bath calibration solutions must be:
(a) Accompanied by a COA;
(b) Five hundred (500) mL in volume; and
(c) Labeled with the lot or batch number, date of preparation, an expiration date that may not exceed one year from the date of preparation, and the value of the reference sample in g/210L.
(d) Changed a minimum of once per day or every twenty-five (25) tests as evidenced by a calibration log that must be maintained at the location of the simulator;
(e) Stored in a climate controlled environment (room temperature); and
(f) Prepared and tested in a laboratory such that their reference value is shown to be traceable to the National Institute of Standards and Technology.
(g) All repairs to the wet bath simulator must be performed the by simulator device manufacturer and only repaired with simulator device manufacturer certified parts.
(9) Dry gas alcohol standards are listed, or approved to be listed on the 2012 NHTSA Conforming Products List of Calibrating Units for Breath Alcohol Testers and certified to a known reference value and traceable to National Institute of Standards and Technology - NIST Traceable Reference Material (NIST-NTRM) ethanol standards. The reference value must be adjusted for the elevation at which the dry gas is being used. Dry gas alcohol standard tanks must be:
(a) Stored in an environment where the temperature range remains between 10° to 40°Celsius (50° to 104° Fahrenheit);
(b) Either labeled or have a COA, which contains the components and concentration of the reference value of the gas, an expiration date that may not exceed three (3) years from the date of preparation, and the lot or batch number;
(c) Taken out of service when the cylinder pressure drops below fifty (50) pounds per square inch (PSI);
(d) Protected from exposure to weather during transport; and
(e) Stored at room temperature for twenty-four (24) hours prior to use to ensure stability.
(10) Each service center using a dry gas alcohol standard must have tubing that is compatible with alcohol (Tygon or equivalent), and purged prior to each calibration unless the system is pressurized.
(11) Any existing manufacturer or manufacturer’s representative operating a device that is calibrated for accuracy using a wet bath simulator on or before December 31, 2019, may continue wet bath calibration through July 31, 2020. Calibrations using a wet bath simulator shall not be utilized by any new manufacturer or manufacturer’s representatives beginning January 1, 2020. Beginning August 1, 2020, no device shall be calibrated for accuracy using a wet bath simulator.
