The Importance of Temperature Calibrations to Quality Assurance in Manufacturing
April 13, 2022
The Importance of Temperature Calibrations
The variable nature of temperature, by definition, makes it one of the more challenging characteristics of the physical world to accurately measure and quantify. Yet, precise levels of heat and/or cold are necessary for certain manufacturing processes to be carried out successfully.
For this reason, temperature is a parameter that must be frequently measured during many industrial processes, not only for quality assurance but in some cases for regulatory compliance.
A Discipline of Precision
In order to assure consistent, reliable temperatures are present within a manufacturing facility and during specific phases of the product-rendering process, consistent accuracy is necessary.
The various mechanical sensors and electronic thermometers in use must be routinely tested and verified for baseline readings which can be compared to an officially recognized, national standard. When an instrument is being used, especially in more extreme temperatures, it can cause the reading to drift.
Since temperature calibrations involve highly-sensitive instruments, these require specialized testing conditions and specially trained technicians to perform the calibration.
This process, in essence, is the verification of sensor performance by comparison to a traceable measurement standard. To achieve this, the temperature measuring device being reviewed is tested in a controlled, stable environment. The device readings are recorded, compared to the “actual” temperature as determined by the standard, and the difference, if any, is noted.
Then, specific adjustments to the device being tested can be made according to procedural protocols based on the type of thermometer in question. It is important that equipment being used for testing and reference is more accurate than the equipment being measured.
A Common Denominator
Temperature calibrations are important to production and applications in a wide variety of industries. The process of manufacturing, depending on the product, can require multiple temperature-controlled phases, periods of extreme heat, cold storage and more.
Some of these industries include aerospace, nuclear power, food and beverage, pet food products, die casting, chemical processing, pharmaceutical, medical supplies, industrial hemp, plastics processing, automotive parts and accessories, rubber tires and components, printing, packaging, energy and power applications and semiconductors, among others.
A2LA stands for the American Association for Laboratory Accreditation. Recognized certification in this arena to the ISO17025 protocols means that our facilities and technicians are proficient in the foremost set of standards used by testing and calibration laboratories. These standards can be referenced by regulatory authorities and jurisdictions and industries which require compliance with specific quality standards. This level of accuracy and consistency allows organizations who work with our labs to provide their personnel with reasonable assurance of safety by minimizing risk through accurate temperature calibrations.
Appendix B Accreditations means that Constellation PowerLabs — an Approved Nuclear Supplier — is routinely audited by NUPIC (Nuclear Procurement Issues Corporation) and NIAC (Nuclear Industry Assessment Corporation). Protocols which satisfy the requirements of 10 CFR 50, Appendix B and 10 CFR 21. These outside agencies assure that Constellation PowerLabs team and facilities exhibit heightened safety and security measures and protocols due to their distinction within the nuclear power industry.
These accreditations instill the highest level of quality in Constellation PowerLabs services, which translates to client confidence in their manufacturing processes and, ultimately, to the consumer in the form of excellent products and services.
