Quality Air Service is pleased to announce that Phoenix Controls air stations, in addition to being NIST traceable, are now NIST accredited through The National Voluntary Laboratory Accreditation Program (NVLAP). NVLAP is a US government agency administered by the National Institute of Standards and Technology (NIST) and is chartered “to accredit public and private laboratories based on their technical qualifications and competence to carry out specific calibrations or tests”. This is an important achievement as Phoenix Controls is now the only air valve manufacturer with NIST accredited calibration procedures and equipment.
Many Venturi valve and terminal box manufacturers claim they are NIST traceable simply by showing their instruments were calibrated by other instruments that are traceable to a NIST Standard. NIST Accredited means that Phoenix Controls air stations passed a specific set of calibration standards per ISO/IEC 17025. The testing was performed by an independent lab, Colorado Experiment Engineering Station Inc. (CEESI), the only NIST Accredited lab for high flow volumetric airflow measurement. NIST Accreditation offers many benefits to the users of Phoenix valves including:
• Validity of test methods and valve calibration
• Peace of mind that the airflow rates delivered by Phoenix valves are accurate
• Increased safety in critical spaces
• Avoid expensive retesting
The Certificate of Valve Characterization has been updated to reflect that Phoenix Controls is now NVLAP Accredited. Additionally, if a copy of the NVLAP certificate is required, it can be requested at the time of order entry.
