Gage certification is the foundation of a gage surveillance program. Gage surveillance is simply an orderly system of keeping records on gages and gage wear. PG&T does supply long form certification for new gages and masters. It is necessary for the gage to be assigned a dedicated I.D. number. If a number or other type of mark is not designated or requested at the time of purchase, an assigned PG&T number will be used.
Re-CertificationWorn gages may be found out of tolerance. At that point the customer is notified, and if a gage can be corrected or repaired the customer is given the choice to purchase a new gage or have their existing gage corrected and then re-certified.
If the customer chooses not to repair their gage or their gage is deemed too costly to repair it is returned to them with an inspection report but it is not re-certified.

Important Facts About Gage Hardness
Just because a gage is made of steel is no guarantee that it is hard enough to withstand the rigors common to railroad gage usage. A gage that is softer than the part it gages may fail. After multiple applications a "too soft" steel gage may become nicked, distorted and worn out. For maximum wear life, PG&T gages are made from the highest quality materials. You’ll always have a greater payback with PG&T.
