Yes, it is important to calibrate feeler gauges to ensure accurate measurements. Calibration involves comparing the gauge readings to a known standard and adjusting as needed to minimize errors. Regular calibration helps maintain the accuracy and reliability of the feeler gauge for precise measurements.
Some common standards used in calibration include ISO 9000 series for quality management, ISO/IEC 17025 for testing and calibration laboratories, and NIST for calibration in the United States. These standards provide guidelines for ensuring accuracy, reliability, and consistency in measurement processes. Adhering to these standards helps to maintain traceability, document procedures, and ensure the reliability of measurement results.
In the light measurement industry calibration standards can refer to both precision light sources and detector based systems ( These are used to calibrate instruments for taking measurements in science and industry. Calibration standards are often traceable to the National Institute of Standards and Technology (NIST). An example of a calibration standard is the RS-12 calibration light source (http://www.gamma-sci.com/products/rs-12-calibration-light-source/). This serves as a white-light standard of spectral radiance and luminance. The TIA 3000 measurement systems are detector-based absolute standards for different high accuracy measurements. Standard calibrations are directly traceable to NIST

Propylparaben is used as a preservative in solutions for High Performance Liquid Chromatography (HPLC) calibration to prevent microbial growth and maintain stability of the calibration standards over time. Its use helps ensure the accuracy and reliability of the HPLC analysis results by preventing degradation of the calibration standards.
A feeler gauge is typically used to measure dynamic valve clearance in internal combustion engines. The gauge is inserted between the valve stem and the rocker arm to determine the correct clearance while the engine is running.

The correct temperature for gauge calibration typically depends on the specific type of gauge and the standards set by industry or regulatory bodies. However, a common reference temperature for many calibration processes is 20°C (68°F). It's important to refer to the gauge manufacturer's specifications and relevant calibration standards to ensure accuracy. Calibration should also be performed under controlled environmental conditions to minimize any potential deviations.

The important point in feer gauges ( also called thickness gages by some of the manufacturers ) is the thickness of the blades. Therefore in order to calibrate a feeler gauge you need to measure the thickness of the gauge at various locations along the length of the device. The standard used in the calibration should satisfy a TUR ( Test Uncertainty Ratio ) of at least 4:1 in order to limit the FAR ( False Accept Risk ) to nearly 2%. Such devices do not require periodic calibration. However, they should be standardized before every use by a standard in order to assure reliable measurements.
To calibrate a feeler gauge using a caliper, measure the thickness of the feeler gauge blades at multiple points along the length using the caliper. Check these measurements against the stated thickness of the blades to ensure accuracy. Make any necessary adjustments to the feeler gauge if the measurements deviate significantly.

A feeler gauge is actually a set of very fine strips of steel used to measure small gaps such as plug gap of an auto plug, or gaps in bearing surfaces.
The first generation of electronic ignition systems had a requirement to set the air gap between the reluctor and the pickup. It had to be set with a non ferrous metal gauge. That is why the brass blade in a feeler gauge set.

Adjusting the valves on a Caterpillar C 15 Engine is easy and does not take long at all. All you need is a wrench and a feeler gauge, You will then loosen up the bolt, place the feeler gauge in between the rocker arm and valve and then turn the wrench until the rocker arm touches the feeler gauge.
When was the last time you changed your spark plugs and wires? DO NOT USE A FEELER GAUGE ON THE PLUGS... THEY ARE PRESET AT THE FACTORY AND A FEELER GAUGE OR GAPPING TOOL WILL RUIN THE PLATINUM COATING.
