AS9100 and Calibration: It's time to get real!

AS9100 standards are on schedule for 2016 revision publication.

MRO or Manufacturer: changes are coming.  Will you be prepared?

AS9110- It is critical that you support your airworthiness operations with a thorouhly vetted calibration prgram. What is your selection process for a calibration vendor? Do you require ISO17025 accreditation?world_quality_month_2015.jpg

AS9115- How are handling your calibration asset management? Document control? With the advent of more cloud based programs cybersecurity measures must be in place to ensure records integrity.

AS9120-Inspection is a crtical peice in the prevention of counterfeit parts. Is your current calibration schedule adequate? How are you determining calibration intervals?


The IAQG (International Areospace Quality Group) has an excellent synopsis of the changes that will be rolled out.

If you are not using an ISO 17025 accredited calibration company you may want to learn more about the difference between ISO9001 or ISO17025 accreditation.

The reality is not every ISO 17025 accredited calibration laboratory is capable and competent to perform your specific calibration.  A calibration laboratory's competence is stated in their Scope of Accreditation.

The Scope of Accreditation tells you what specialties (Disciplines) have been validated by an independent accreditation body and what is the best measurement they can provide.  These 2 pieces of information are critical when selecting a calibration provider.


Review the Scope of Accreditation and best measurement capability before issuing a purchase order.


Best Measurement 

An ISO 17025 accredited laboratory will have a stated measurement uncertainty for each discipline on its scope of accreditation.

This measurement uncertainty allows the end user to evaluate a calibration laboratory's best measurement capability. This really does make a difference. If you need a device calibrated that can measure 1 psi does it make sense to have it calibrated  by a laboratory that has its best measurement capability of +/- 5 psi?



Wouldn't it be nice if there was a checklist:

Laboratory Accreditation Bureau- LAB- an independent 3rd party accreditation body has developed a guide for the Purchasing and Evaluation of Calibration.  Appendix A and B in this document are checklists that will guide you in evaluating potential calibration suppliers.

How to get the BEST calibration quote

Think about how you use the item that is going to be calibrated.  Here is the information you need to provide your calibration provider:

  • A unique identifier for each item submitted for calibration.
  • Specific calibration points to checked or number of measurements across a range.
  • The calibration interval- how often it needs to be calibrated.
  • Any specific industry standards or procedures to be followed.
  • Calibration report to contain before and after data.
  • Calibration report to contain measurement uncertainty.

Some calibration companies charge extra for the above services and you need to specify this on your  RFQ to determine the total cost.
