scope:

This standard specifies processes to identify, register and calibrate all IMTE. It is applicable when new IMTE is brought into use and to IMTE already in use. It is also applicable to IMTE obtained indirectly (e.g. as part of project works).

This standard is applicable to all functions within Network Rail that either directly or indirectly use IMTE on Network Rail infrastructure, including safety critical work.

Appendix A specifies categories of IMTE that require calibration or checking before use; the standard that each item shall be calibrated to; and/or, the checks that are made before each item is used.

Contractors that use IMTE on Network Rail infrastructure are not included within the scope of this standard. However, they are expected to have processes in place to control their IMTE

Purpose

This standard provides for the control and calibration of inspection, measuring and test equipment (IMTE) and specific tools. Examples of IMTE and specific tools are:

• Track Level Gauges

• Signalling measuring instruments

• Electrification & Plant Height and Stagger gauges

• Torque Wrenches
