It is generally known that the precision of measuring systems plays a very important part in modern quality assurance, where products are required to meet ever stringent tolerances. The standard gauge block is commonly used for dimensional measuring tool calibration in almost every calibration lab. So, to make sure the calibration provider delivers their best service, the standard gauge block should not only have the right properties as specified in ISO 3650, but it must also allow the laboratory to reduce operation costs and time as well.
There are 3 types of standard gauge blocks used nowadays; steel, ceramic and carbide. Each of them has specific strong and weak points, which are as described below:
1. Mechanical properties: all 3 types of material demonstrate the same degree of flatness, parallelism and wring capability. Though we can see the thermal expansion coefficient of ceramic is less than others, as the calibration laboratory is strictly required to control the temperature, this thermal characteristic should not play an important role.
2. Usability: all 3 materials have different strong and weak points in themselves, so none of the materials are clearly better than the others.
3. Maintenance: the ceramic gauge clocks are totally corrosion free, thus requiring no protection. This helps the lab save both maintenance oil and time.
4. Cost: the standard gauge block made from ceramic is the most expensive.
In summary, we have found that the standard gauge block made from ceramic is the most attractive compared to the steel and carbide. However, it is still not widely used because of its high cost. If its cost is reduced to the same level as steel and carbide, the ceramic standard gauge block will be the most attractive one.
