At Envitest Laboratories, we understand the importance of maintaining high standards of accuracy and reliability in our testing and calibration processes. A key aspect of this is adhering to the stringent requirements of ISO/IEC 17025:2017, which focuses on the facilities and environmental conditions essential for ensuring that results are valid, accurate, and reliable.
Clause 6.3 addresses the environmental factors that can affect the quality of tests and calibrations. It specifies that laboratories must document, control, record, and maintain suitable environmental conditions, particularly where these conditions have a direct impact on the validity of results. At Envitest, we have implemented rigorous measures to ensure compliance with this standard, ensuring that our clients receive the most reliable results possible.
Key Environmental Conditions to Consider
Several critical environmental factors can influence the outcome of tests and calibrations. Below, we discuss these key conditions and how we manage them in line with the requirements of ISO/IEC 17025:2017.
- Importance: Maintaining a consistent temperature is crucial for preventing thermal degradation or alteration of samples and ensuring the proper functioning of instruments.
- Control Measures: At Envitest, we maintain a controlled temperature range, typically between 20°C and 25°C, to ensure the stability of samples and equipment during testing processes.
- Importance: Excessive humidity can affect materials and equipment, leading to unreliable results due to moisture-related effects.
- Control Measures: We monitor and controlrelative humidity levels within the range of 40% to 60% to minimize any potential moisture interference with testing and calibration activities.
- Importance: Adequate lighting is essential for precise visual inspections and accurate measurements, particularly when working with sensitive instruments or delicate samples.
- Control Measures: We ensure that our laboratory spaces have appropriate lighting intensity and spectrum to facilitate clear visual assessments and measurement accuracy.
- Importance: For reliable electrical measurements and uninterrupted operations of sensitive equipment, a stable electrical supply is essential.
- Control Measures: We maintain a steady 240V electrical supply with protective measures to prevent power fluctuations or interruptions that could disrupt tests and measurements.
- Importance: Contaminants such as dust or airborne chemicals can interfere with sensitive testing procedures, leading to contamination or inaccurate results.
- Control Measures: We ensure a clean air environment in our laboratories by using filtration systems and strict protocols for minimizing contaminants.
- Importance: Vibration can affect the precision of sensitive instruments and compromise the accuracy of measurements.
- Control Measures: Our laboratory facilities are equipped with anti-vibration mechanisms to minimize vibrations, particularly in areas where sensitive equipment is used.
- Importance: Excessive noise can interfere with acoustic measurements or affect concentration during critical testing processes.
- Control Measures: We control noise levels to ensure that our testing environments are conducive to accurate acoustic measurements and focused laboratory work.
- Importance: EMI can corrupt data and distort the results of electrical measurements, making it crucial to shield equipment from interference.
- Control Measures: At Envitest, we implement effective shielding and isolation techniques to protect sensitive instruments from EMI, ensuring the integrity of our data.
- Importance: Maintaining a clean laboratory environment is critical to preventing cross-contamination and ensuring the validity of test results.
- Control Measures: Our laboratories follow strict cleanliness protocols, including regular cleaning, the use of controlled environments, and careful handling of materials to prevent contamination.

Ensuring Compliance with ISO/IEC 17025:2017
To maintain compliance with ISO/IEC 17025:2017 Clause 6.3, we follow several key practices:
- We conduct thorough assessments to identify any environmental conditions that could affect the accuracy and reliability of our test and calibration processes. These factors are carefully monitored and controlled to mitigate any adverse impacts.
- All critical environmental conditions are continuously monitored and recorded using calibrated instruments. This includes tracking temperature, humidity, air quality, and other relevant factors to ensure consistency and compliance with established standards.
- We have detailed procedures in place for maintaining and calibrating our environmental control systems. Regular checks and calibrations ensure that our equipment and facilities continue to meet the stringent requirements of ISO/IEC 17025:2017.
