Frequently Asked Questions (FAQ)

The following is a list of Frequently Asked Questions about Maintenance and Calibration of Laboratory Equipment. If the information you need isn’t supplied here, we recommend contacting us and we’ll be happy to help you out.

What is the objective of Preventive Maintenance ?

The main objective of Preventive Maintenance is to prevent the failure of Equipment before it actually occurs. Preventive Maintenance is a schedule of planned Maintenance for cost-effective treatments to an existing System that preserves the System, delay future deterioration, and maintains or improves the functional condition of the System.

What is the goal of Preventive Maintenance ?

  • To avoid the consequences and high costs associated with untimely failure of Equipment
  • Preventive Maintenance is designed to preserve and enhance Equipment reliability by replacing worn components before they actually fail.

What are the benefits of Preventive Maintenance ?

  • Extend the life of Equipment
  • Minimize the breakdown time
  • Maximize the productivity
  • Keep the equipment operating within specification.
  • Improve System reliability

Quality Management System (QMS) requires an implementation of Preventive Maintenance Program.

What is Calibration ?

  • Equipment Calibration is purely an indication that the instrument was found to be performing within its specification at the time of Calibration, and only at the time of Calibration.  It proves that the Equipment is operating to the manufacturer’s Standards.
  • Calibration is a comparison between Measurements – one of known magnitude or correctness made or set with one device and another measurement made in as similar a way as possible with a second device.

How often do I need to calibrate my Equipment ?

  • Although there are exceptions to the rule, most Equipment should generally be calibrated half-yearly/annually or if you suspect that readings may be incorrect or out of specification.

What are the benefits of Calibration ?

  • For better precision and higher accuracy of test results
  • Traceability of Measurements and Calibrations to NIST-USA, NPL-UK, and/or to any recognized National or International Standards.
  • Ensure reliability by performing Calibrations in accordance with, strict compliance to ISO17025 requirements.

Why Lab Equipment should be Calibrated by an ISO 17025 Accredited Calibration Laboratory ?

  • Having your Lab Equipment Calibrated by an ISO 17025 Accredited Calibration Laboratory will provide assurance that they can supply with accurate and reliable results.
  • Calibration Certificate issued by an Accredited Calibration Laboratory will also satisfy Equipment Calibration requirements by an external Auditor or Assessor such as Certification Body – ISO 9001 and Accreditation Body – ISO 17025.
  • If you are planning for ISO 17025 Accreditation of your Lab, then your Lab Equipment should be Calibrated by an
    ISO 17025 Accredited Calibration Laboratory.

Why Calibration Laboratory should be Accredited to ISO 17025 ?

  • Laboratory Accreditation is a means of determining the technical competence of a Laboratory to perform Measurement and Calibration.
  • For the implementation of Quality Management System (QMS) as required by ISO 17025.
