Calibrated Leak Standards (Leak Orifice)

The common purpose of a Calibrated Leak Standard (leak orifice) is to calibrate a leak test program or simulate the characteristics of a “leaking or failed” part condition. At LeakMaster we manufacture and recertify thousands of air flow leak standards annually for a wide range of industries. Each leak standard is meticulously manufactured to a specific leak or flow rate at a predetermined pressure and can be adapted to a range of quick-connect or threaded fittings. Air Flow Leak Standard Specifications +/- 1.5% Uncertainty of stated flow rate or .1 sccm (whichever is greater) Pressure Ranges from -14 to 150 PSIG Flow Rates from 0.5 to 100,000 sccm Stainless Steel and Aluminum Construction LeakMaster is accredited to ISO/IEC 17025:2017 by the American Association for Laboratory Accreditation (A2LA) for the technical competence in the field of calibration. Leak Standard Recertification Manufacturers worldwide trust LeakMaster's calibrated leaks to gauge the quality and validity of their testing processes. Calibrated leaks provide confidence and peace of mind, giving the user a repeatable, accredited leak standard to teach or challenge the leak testing or flow testing process. Need a leak recertification for one of your existing leaks that was not manufactured by LeakMaster? No problem, we also re-certify other manufacturers calibrated leaks with our modern calibration equipment. For precision-engineered leak testing solutions and calibrated leaks, you can trust LeakMaster.

We’ve partnered with the world’s largest medical manufacturers to provide leading-edge technology including turnkey leak testing systems and instrumentation such as our UltraFlow V3, Guardian, Defender, and Stealth leak testers. Our vast experience in the assembly and testing of medical devices provides a unique advantage, allowing us to successfully guide our customers to select the correct leak tester for their application, the first time. Several leak testing methods are employed for medical device leak testing, including water immersion, pressure or vacuum decay and mass-flow air testing, and tracer gas. LeakMaster manufactures all air testing methods, and focuses on air leak testing solutions due to their lower cost, ease of use and testing accuracy including: Pressure Decay -This popular air leak test method involves pressurizing the medical device with a specified air pressure. After a stabilization period, the instrument monitors for any decrease in air pressure over time, indicating a leak. Vacuum Decay - Operating opposite to pressure decay, with vacuum decay the part is evacuated and monitored for a pressure rise (loss of vacuum) indicating a leak. A secondary method for sealed components places the medical device in a sealed chamber and extracts surrounding air. An increase in chamber pressure suggests a leak in the test part. For peace of mind, all LeakMaster leak testers can perform a pressure decay test and most can be optioned to perform a vacuum decay leak test as well. From our budget friendly pressure decay Defender to our configurable, flagship Guardian , LeakMaster provides excellent value and a range of test possibilities within one instrument. Mass Flow - The mass-flow technique measures the rate at which air flows through a medical device or test piece. With this technique the device is pressurized. Once the pressure is relatively stable, the mass-flow sensor measures the amount of air mass needed to maintain internal device pressure. Continuous air flow into the medical device indicates a leak. A higher air requirement indicates a larger leak. Our Guardian and UltraFlow leak testers can be configured as pressure decay and mass-flow combination units, providing exceptional value and a range of test options within the same instrument.
