Pressure Decay Test Method Guide

There are many different types of leak testing, so when you must test for leaks in the factory or the field, it pays to know which leak test is best for the task. Pressure decay testing is one of the most popular forms of leak testing because it is accurate and relatively easy. Read More

Overview of Mass Flow Testing

When testing parts, if your part-to-part volume differs by more than 5-10% or if you are testing a device that needs to accommodate fluid or air passing through it, chances are you need mass flow testing. Mass flow testing defines the rate of flow through a part or device and is typically conducted ... Read More

Convert Dunk Testing from Bubbles to Measurable Leak Testing

The simplest and least expensive type of leak rate test is dunk testing for bubbles. Even if you know nothing about leak testing, you have probably used a bucket of water to find a leak in an inner tube by looking for bubbles. The principle is always the same—immerse the part and look for bubbles ... Read More

7 Factors Affecting Your Leak Test

If you know anything about leak testing, then you understand that everything leaks. The question is: How much leakage is considered acceptable? For accurate leak testing—and more importantly, accurate leak measurement—you need a repeatable test that gives you an accurate baseline. Read More

5 simple ways to improve your leak test

Leak testing is a common requirement on the production line. It is an important test that ensures the proper functioning of a part or assembly in the field. Due to the importance of this test, it is essential to make sure your test system is always functioning and performing at its best. There is ... Read More

6 things you didn’t know you could do with the Sentinel I28

Cincinnati Test Systems’ Sentinel I28 is a popular instrument for use by our customers because it is one of the most advanced multi-functional test instruments on the market. It is a flexible instrument, configurable for a variety of pressure decay and mass flow testing requirements. Read More

Optical device leak testing: Ensuring military-grade devices stand up to harsh environmental conditions

Military-grade optical sighting devices are an excellent example of how determining the right leak test for the job isn’t just a matter of desired test cycle time and target leak rate. We must always consider the application for the device and the environmental extremes in which it will be used. ... Read More

What is a differential pressure decay leak test and when is it used?

Pressure decay leak testing is sensitive to very small leaks, economical, and reasonably simple to implement. But to ensure a reliable and repeatable test result, it must be calibrated to an accurate leak standard, defined by volumetric flow, test pressure, and the test volume of the part. Read More

Optimizing your leak test station: The importance of plumbing and fixturing

A leak test that is reliable, repeatable, and fast enough to keep pace with production begins with how the test part is connected to the test instrument.  Let’s start with the obvious – the primary cause of misleading test results is leaking seals and fittings. Choosing an ideal seal The best seals ... Read More

Ideal methods for IP67 device and sealed component leak testing

In our previous post, we discussed the use and parameters of IP67 (and IPxx) ratings. In this post, we will discuss ideal methods for IP67 device and sealed component leak testing. The ideal approach for leak testing to the IP67 standard is to test with air, using a volumetric fill test with ... Read More
