Reference length with gauge blocks
Use individual gauge blocks or wrung combinations to establish reference lengths for setting and verifying dimensional measuring instruments.

Standards & Setting Gauges
Select Mahr reference standards and setting gauges for the dimensions your inspection process depends on. Compare gauge blocks, pin gauges and setting rings or plugs, then specify size, grade and documentation.
What can you measure?
Setting internal measurements
Use setting rings of a specified reference diameter to set compatible bore gauges and inside measuring instruments. Select the nominal size and calibration requirements.
Cylindrical reference dimensions
Use pin gauges or setting plugs to establish specified cylindrical reference sizes. Distinguish setting references from limit gauges used for component acceptance.

Models and measurement options
| Model / option | Range or configuration | Selection notes |
|---|---|---|
| Gauge blocks | Reference lengths | Select nominal lengths, set composition, material and grade. |
| Pin gauges | Cylindrical reference sizes | Select individual sizes or a set to suit the inspection plan. |
| Setting rings | Internal setting references | Match the nominal size and documentation to the bore-measurement setup. |
| Setting plugs and other standards | External or instrument-specific references | Confirm contact geometry, size and compatibility with the instrument. |
Ranges refer to specific variants or sets. Confirm the exact model, configuration and accessories with your quotation.
What to consider before choosing
Reference size
List the nominal sizes and tolerances; distinguish the reference from the component acceptance limit.
Material and grade
Specify the working environment, handling frequency and required reference quality.
Documentation
State certificate, traceability and recalibration requirements when requesting a quotation.
Frequently asked questions
Should I order individual standards or a complete set?
Choose individual standards when only a few fixed dimensions need to be set or checked. A set may be more useful when the inspection room handles several sizes. List the actual reference dimensions so unnecessary sizes can be avoided.
Which grade and calibration documentation should I request?
State how the standard will be used and the required measurement uncertainty or quality procedure. The grade, material and certificate requirements should follow that use; do not choose solely by nominal size.
What information is needed to order a setting ring or plug?
Provide the nominal diameter, required tolerance, instrument to be set and certificate requirements. Clarify whether it is a setting reference or a component acceptance gauge, because those purposes are different.
