How do I Make Sure My Equipment is Calibrated?

Avoiding Errors: How to Guarantee Your Equipment is Calibrated Properly


Calibration is the unsung hero in the world of precision, accuracy, and safety. Whether it’s in a high-tech laboratory, an industrial manufacturing plant, or a medical facility, the reliability of equipment hinges on its calibration. This process ensures that instruments measure within specified limits by comparing them against a standard known to be accurate. But why is calibration so critical, and how can one ensure their equipment remains faultlessly calibrated?

The consequences of uncalibrated or improperly calibrated equipment can range from minor inaccuracies to significant errors, potentially leading to safety hazards, quality control issues, and financial losses. In industries where precision is non-negotiable, such as healthcare, engineering, and research, calibration becomes a pivotal part of routine operations.

However, ensuring your equipment is calibrated correctly is not always straightforward. It involves understanding international standards, recognizing when and how often calibration should occur, and choosing the right service provider for the task. Oakrange wants to help you understand the calibration process, offering a step-by-step guide to maintaining the accuracy and reliability of your equipment. By adhering to best practices and maintaining a rigorous calibration schedule, you can avoid errors and ensure your operations run smoothly and safely.

Understanding Calibration Standards

The Foundation of Precision

Calibration standards serve as the benchmark for ensuring equipment accuracy across various industries. These standards are not arbitrary; they are developed through rigorous scientific research and industry consensus to ensure that instruments perform as expected, providing results that are both accurate and repeatable.

International and Industry-Specific Standards

At the international level, standards such as ISO/IEC 17025 provide guidelines for calibration and testing laboratories, ensuring competence and consistent operation. This standard is recognized globally, offering a framework for laboratories to demonstrate they operate competently and generate valid results, thereby promoting confidence in their calibration services.

Industry-specific standards also play a crucial role, catering to the unique requirements of sectors such as aerospace (AS9100), automotive (ISO/TS 16949), and healthcare (ISO 13485). These standards consider the specific needs and challenges of each industry, ensuring that calibration processes are tailored to meet those demands.

Certification Bodies and Importance of Adherence

Accreditation bodies, such as the American Association for Laboratory Accreditation (A2LA) in the United States or the United Kingdom Accreditation Service (UKAS) in the UK, assess laboratories against these standards to certify their competence. Holding accreditation from such bodies signifies a laboratory’s commitment to maintaining high standards of accuracy and reliability in calibration.

Adhering to these standards is not just about compliance; it’s about commitment to quality, safety, and efficiency. It ensures that equipment, regardless of where it’s used, meets a universally accepted level of performance, thereby safeguarding operations, products, and services against the risks of inaccuracies and inconsistencies.


Understanding and adhering to calibration standards is the first step in ensuring your equipment is calibrated correctly. By familiarizing yourself with the relevant standards and ensuring your service provider is accredited, you can maintain the precision and reliability of your equipment, ultimately avoiding costly errors and enhancing operational safety.
