Gauge Certification

Gage certification is the foundation of a railroad gauge surveillance program. Gage surveillance is simply an orderly system of keeping records on railroad gauge wear. PG&T supplies long form certification for new gauges and masters. Each receives a dedicated I.D. number.  An assigned PG&T number will be used if a number or other type of mark is not designated or requested at the time of purchase.

Long Form Certification

  • Long form certification certifies the actual measurement of all specific critical dimensions and critical characteristics for a particular railroad gauge.
  • One railroad gauge per long form certification. (See certification marking).
  • This certification also provides certification of N.I.S.T trace-ability

The certification document prepared for these items includes the following:

  • Name and address of organization providing the certification
  • Customer name (company and or person) and company address
  • Control number, unique to the railroad gauge
  • Description of the gauge
  • Description of measurement and test equipment used to perform calibration Certification date
  • Gage certification date
  • Calibration interval (If desired by customer)
  • Identification of calibration procedure/method used
  • Assigned certification value(s) and critical characteristics when applicable
  • Certification uncertainty or reference to specification, drawing, or other document specifying tolerance limits
  • Applicable corrections
  • Special use limitations or certifications status, when applicable
  • Identification of person performing calibration/certification
  • Identification of person authorized to review and approve validity of certification

Important Facts About Railroad Gauge Hardness

A railroad gauge that is softer than the part it gauges or measures, may fail.  After multiple applications a soft steel gauge may become nicked, distorted and worn out. For maximum wear life,  our railroad gauges are made from the highest quality materials. You’ll always have a greater payback with Precision Gage & Tool.
