Leak FAQ

A leak standard is a precision-calibrated device used to verify and validate the calibration of air leak and flow test systems. It provides a known, traceable flow rate that can be used to confirm the accuracy of testing equipment. 

Leak standards help ensure your leak and flow testing equipment remains accurate and reliable. Regular verification with a calibrated standard reduces measurement uncertainty and supports quality control requirements. 

Yes. CTS air flow leak standards are manufactured in an A2LA-accredited, ISO 17025 laboratory and are supplied with a calibration certificate that is traceable to NIST standards. 

A certificate of calibration will accompany any new or recertified leak standard. As well as a label affixed to the leak standard that lists the serial number, leak rate, pressure, and calibration date. 

CTS can provide leak and flow standards ranging from approximately 1×10⁻⁵atm-cc/sec up to 50,000scc/min, allowing users to verify a wide variety of leak and flow testing applications. 

Standard holders are available for pressures ranging from -14.7 to 250 psig (-1.0 to 17.2 bar). If application requires higher pressure, CTS offers solutions up to 3,000 psig (207 bar). Contact us for more information.

CTS offers a wide variety of connection styles, including FNPT, MNPT, Swagelok®,Staubli®, Colder CPC®, Festo®, metric threaded fittings, and other specialized configurations designed to integrate with existing test systems.

Yes. CTS offers numerous holder and connection options that are designed to integrate seamlessly into existing leak testers, test lines, manifolds, and calibration processes.

CTS leak standard certificates do not list an expiration date, but CTS suggests annual recertification to ensure leak standards are reading as they should. For CTS manufactured leak standards, if it is found out of tolerance during recertification, it is replaced with a new leak standard at no additional charge.
