APTA STANDARDS DEVEL OPMENT PROGRAM APTA RT-VIM-S-017-03 Rev 2 STANDARD First Published September 28, 2003 American Public Transportation Association First Revision November 2, 2006 (Reaffirmed) 1300 I Street NW, Suite 1200 Second Revision January 6, 2015 (Reaffirmed) Washington, DC, 20005 Rail Transit Standards Vehicle Inspection and Maintenance Working Group Calibration of Inspection and Maintenance Precision Measuring Devices and Tools Abstract: This Standard covers basic procedures for calibration of inspection and maintenance precision measuring devices and tools. Keywords: calibration, precision measuring device, tools Summary: This document establishes a standard for the calibration of precision measuring devices and tools used by vehicle maintenance departments within a rail transit system. Rail transit systems shall tailor this standard to accommodate their specific equipment and mode of operation. Scope and purpose: This standard, in combination with the ISO standard referenced, includes all essential periodic inspection and maintenance requirements for the calibration of precision measuring devices and tools used to inspect and maintain rail vehicles. This procedure covers all types of electronic test equipment, mechanical tools and measuring devices used to generate quantitative measurements and/or data. Calibration and certification is based on standards set by the National Institute of Science and Technology, original equipment manufacturers’ recommended calibration cycles, and a transit agency’s specifications. This standard is intended for use by the vehicle maintenance department within a rail transit system. It establishes procedures for the periodic calibration of inspection and maintenance of precision measuring devices and tools to ensure the accuracy of measurements obtained by these devices. This document represents a common viewpoint of those parties concerned with its provisions, namely operating/ planning agencies, manufacturers, consultants, engineers and general interest groups. The application of any standards, recommended practices or guidelines contained herein is voluntary. In some cases, federal and/or state regulations govern portions of a transit system’s operations. In those cases, the government regulations take precedence over this standard. The North American Transit Services Association (NATSA) and its parent organization APTA recognize that for certain applications, the standards or practices, as implemented by individual agencies, may be either more or less restrictive than those given in this document. © 2016 NATSA and its parent organization.

This Standard for the Calibration of Inspection and Maintenance Precision Measuring Devices and Tools for rail transit vehicles represents a common viewpoint of those parties concerned with its provisions, namely, transit operating/planning agencies, manufacturers, consultants, engineers and general interest groups. The application of any standards, practices or guidelines contained herein is voluntary. In some cases, federal and/or state regulations govern portions of a rail transit system’s operations. In those cases, the government regulations take precedence over this standard. APTA recognizes that for certain applications, the standards or practices, as implemented by individual rail transit systems, may be either more or less restrictive than those given in this document. This Standard describes the basic inspection and maintenance requirements for the calibration of rail transit precision measuring devices and tools. APTA recommends the use of this standard by individuals or organizations that use measuring devices and tools to make quantitative measurements to demonstrate compliance with a specified requirement. Note on alternate practices Individual rail transit systems may modify the practices in this standard to accommodate their specific equipment and mode of operation. APTA recognizes that some rail transit systems may have unique operating environments that make strict compliance with every provision of this standard impossible. As a result, certain rail transit systems may need to implement the standards and practices herein in ways that are more or less restrictive than this document prescribes. A rail transit system may develop alternates to APTA standards so long as the alternates are based on a safe operating history and are described and documented in the system’s safety program plan (or another document that is referenced in the system safety program plan). Documentation of alternate practices shall: identify the specific APTA rail transit safety standard requirements that cannot be met; state why each of these requirements cannot be met; describe the alternate methods used; and describe and substantiate how the alternate methods do not compromise safety and provide a level of safety equivalent to the practices in the APTA safety standard (operating histories or hazard analysis findings may be used to substantiate this claim). © 2016 American Public Transportation Association | iii APTA RT-VIM-S-017-03 Rev 2 Calibration of Inspection and Maintenance Precision Measuring Devices and Tools Calibration of Inspection and Maintenance Precision Measuring Devices and Tools 1. Frequency of conduct This section provides guidance to the rail transit system (RTS) to develop initial calibration and audit programs. In implementing this Standard, frequencies for individual tasks shall be established based on a number of factors, including but not limited to the following: operating environment/conditions OEM-recommended intervals performance requirements historical data failure analysis reliability-centered maintenance programs industry experience rail transit system’s testing and experience NOTE: In the absence of experience, recommendations or history, initial calibration and audit intervals shall be as specified below. 1.1 Calibration intervals Precision measuring devices and tools shall be inspected, repaired and calibrated at regular intervals for proper operation and accuracy. A periodic precision measuring device and tool recalibration program shall be developed based upon the measurement equipment’s stability, purpose, usage and environmental conditions. Table 1 establishes the initial calibration interval for equipment that has seen normal operating conditions.
