Cirris Certifications

Cirris has achieved certain certifications to elevate practices that will help ensure the continued high quality and reliability of Cirris products. Our improvement initiatives prompted us to take this important step toward further meeting the needs of our customers. As always, our overall mission remains to provide the best ownership experience for all our valued customers.



    ISO 9001:2015

    In 1994, Cirris implemented ISO 9001 to maintain an organized and efficient business. This quality management system is used globally to ensure the highest standards of service. The 2015 version of ISO 9001 has a stronger focus on performance and processes suited to each organization’s needs. It also requires stronger accountability from upper management and more consideration of risk when implementing strategies.



    The AS9100D standard strives to hold companies accountable for the safety and quality of their products. This is especially crucial in the aerospace industry where safety is a top priority. Therefore, the standard doubled the number of requirements in ISO 9001:2015 to include important regulations that ensure safety such as ESD prevention and FOD control. Also included are cleanliness inspections and part accountability to ensure every piece of an aircraft will keep those aboard safe.

Cirris Compliances

Cirris has strived to remain compliant with standards related to our products. Compliance with these standards means we can work with customers to help keep their testers running smoothly.

Cirris Systems Cable Tester ManufacturingZ540 – Calibration

Cirris Systems is in compliance with both the MIL-STD-45662A and Z540-1 standards. While Cirris systems is not a calibration laboratory, we are the OEM (original equipment manufacturer) and have the rights, responsibility, and authority to calibrate our own manufactured test equipment. An OEM is not required to be certified as a calibration laboratory. All certificates of calibration issued by Cirris reflect this calibration status. Cirris’ quality procedures, including calibration, are continually reviewed by both internal Cirris auditors and the external auditors representing Intertek.

NIST – Traceability

When the NIST (National Institute of Standards & Technology) confirms the accuracy of a test instrument’s ability to measure a given unit, an NIST number is assigned to that instrument for that unit of measure. NIST numbers are sometimes displayed on calibration certificates to demonstrate some evidence of NIST traceability. In recent years some calibration laboratories have discontinued displaying NIST numbers on calibration certificates in order to reduce calibration costs.

At this time Cirris does not receive NIST numbers on certificates for instruments used in calibration, and therefore cannot provide NIST numbers on calibration certificates for Cirris test equipment. Please note there is nothing in MIL-STD-45662A, Z540-1 or ISO 10012-1 that requires NIST numbers be maintained for each successive calibration to demonstrate traceability.

Measurement Uncertainty

Cirris follows the guidance in ANSI/NCSL Z540-1-1994, paragraph 10.2(b). Any standard used to calibrate a tester must have at least four times more accuracy than the measurement specs of the Cirris tester being verified. Cirris’ Performance Check Kits are manufactured and verified to meet or exceed this 4:1 ratio requirement.
