InterTech Launches New Universal Leak Detector That Eliminates Part Volume Concerns – Universal Audit Tester

Posted by:

Now, one leak tester from InterTech does the job of many specialized instruments and is ideal for quality control in the lab: the new M1075-121y Universal Audit Tester.

The difference between this test instrument and others in the industry is a design breakthrough that eliminates the need for part volume matching as required in pressure decay methods.

“This is a transformative development in leak testing applications that require quick changeover and flexibility,” said InterTech President, Mr. Jacques Hoffmann. “It changes fundamental issues. We eliminate the need for specialized leak testing instruments in the lab. Now, the same instrument can be used for a large engine casting or a small solenoid – just change the part and go.”

Until development of the M1075-121y Universal Audit Tester, “small” parts required instruments with a “small” built-in reservoir, and “large” parts had to be tested on different instruments with correspondingly bigger reservoirs.

Specialized instruments are still best where application speed is paramount, according to Mr. Hoffmann, but he points out that as the instrument’s name suggests (Universal Audit Tester), this new & superior instrument is for labs and quality engineers.

“Whether it is incoming inspection, product development or supplier development, this is how to control costs and stay flexible, and more elegant compared to custom instrumentation dictated by part size or material properties,” said Mr. Hoffmann. “Now, with one leak test instrument from InterTech, quality engineers have more flexibility than they’ve ever had.”

Leak gaging with the M1075-121y covers a much wider range than other models. It handles an amazing array of volumes from 5 to 800 sccm. A bar code scanner interface, simplified calibration and touch screen menus make operation easy and intuitive.

Leak testing 101 – Part 2

Posted by:

In part one of this series, we considered the pros and cons of pressure-decay testing. In part two, we’ll take a close look at a leak-testing method called “differential pressure decay.”

This method is similar to simple pressure-decay testing discussed in part one.A more accurate variant of the pressure-decay method, differential pressure testing involves pressurizing a reference volume along with a test part. The pressure differential between the non-leaking reference volume and the test item is then measured by a transducer over time, as shown in figure 1. This method requires measuring pressure at two points in time to obtain a pressure change reading. It is an indirect method of measuring leakage rate because the time and pressure data must be converted into leakage rate. This method allows you to use a higher-resolution pressure transducer.

Differential Pressure Decay Method of Leak Testing

Differential Pressure Decay

Figure 1: With valves 1 and 2 open, the test item and reference volume are pressurized and then isolated by closing valve 1. The reference volume is then isolated from the test item by closing valve 2. The transducer reads the pressure differential between the reference volume and test item twice over time.

A down side to this method is that the larger the volume, the smaller the change in pressure for a given leak rate, resulting in longer test times as test volume increases. All temperature effects are the same as for pressure decay.

Differential pressure-decay testing is widely used. Unfortunately, in many instances it is the default choice of manufacturing and quality engineers who don’t understand the true cost of this type of testing. They could eliminate these hidden costs by using mass-flow leak detectors, another dry air-leak testing method that will be discussed in part three.

Moreover, the indirect nature of the test process and the time needed to track pressure changes and take two measurements create inherently longer testing times. This means a greater probability of measurement error exists than for methods that require only one measurement. The probability of measurement error is directly related to the interval length between the two measurements. These factors are what lead many technicians to use mass-flow leak testing.

That said, it should be noted that for many applications at pressures in excess of 150 psig, differential pressure-decay leak testing remains the method of choice. Granted, test cycle times are slower than with single-measurement leak test methods, however, this drawback is outweighed by the lower costs for instrumentation. Basically, choosing between pressure decay or differential pressure-decay test methods involves a trade-off between cycle time and instrument cost.

In part three of “Leak Testing 101,” we will discuss the mass-flow leak testing method: how it works, and the pros and cons vis-à-vis helium and pressure-decay testing. I’ll explain how to implement this technique to get accurate gauge repeatability and reproducibility (R&R).

Leak testing 101 – Part 1

Posted by:

Not too long ago, when you wanted a product to be leak-proof, you simply put it under water, made sure it didn’t bubble, and thereby concluded there were no leaks. Such “bubble testing” takes time and depends on the operator’s ability, making it totally inappropriate for the modern production environment. Also, it doesn’t generate the quantitative measurements that are the lifeblood of quality assurance engineering.

Dry-air leak testing methods—some of which can detect leaks as small as 0.01 standard cubic centimeters per minute (sccm)—are the methods most commonly used today by a wide range of industries—from medical devices, to automotive, to appliances, and aerospace, among others. These dry air methods enable quality managers to define leaks quantitatively.

“No leaks allowed” standards are concepts of the past. There are a variety of dry air leak test methods and best-practice techniques for each type of method, which will enable compliance to ISO 9001 and comparable quality management standards to be achieved. Generally speaking, these dry air leak test methods include;

  • Pressure testing
  • Differential pressure-decay testing
  • Mass flow leak testing

In addition, tracer gas testing and especially helium mass spectrometer leak testing, are used in more demanding applications where leaks as small as 10-5 standard cubic centimeters per second (sccs) must be detected in a production environment. If one truly understands leak testing application requirements and best practice techniques for these various leak test methods, the selection of which type of testing to perform is a rather straightforward matter.

The first step in designing a leak testing solution is to correctly define what the leak limits are. Leak testing applications laboratories begin with an engineering analyses of a specific application to determine and quantify how much a product or component can leak. Often, correlation studies are performed to verify if it is possible to use dry-air test methods instead of hydraulic fluids. Sample parts are tested as part of an initial engineering analysis. These determine the production requirements and leak standards to be achieved so that quality engineering of test solutions can begin. The first step in this process is to select the leak testing method that is the best match to application requirements.

In this “Leak Testing 101” series we will discuss the various dry air leak testing methods and the issues and techniques that affect testing costs and gauge repeatability and reproducibility (GR&R).

First, let’s take a look at the pros and cons of pressure-decay testing.

The big plus of pressure-decay testing—or at least the thought behind it—is that the leak detectors for pressure-decay leak testing have the lowest upfront cost. It is probably for this reason that the method is still in use, although in many applications the real costs of pressure-decay testing are actually much higher than many realize.

In the pressure-decay method for leak testing (see figure 1), a part is pressurized, the test circuit is isolated, and the pressure drop associated with a leak is measured. A transducer reads the pressure change. Calculations then convert these time/pressure readings into a measure of leakage rate. The higher costs of pressure-decay testing stem from the difficulties inherent in the test methodology. Pressure-decay leak testing is relatively difficult because measurements are highly vulnerable to changes in testing conditions such as drafts or temperature and there are often difficulties in determining the volume of test parts and test circuits, which must be known in order to calculate results.

Pressure Decay Method of Dry Air Leak Testing

Pressure Decay Method

Also, pressure-decay leak testing requires two measurements of pressure with sufficient elapsed time between measurements. When speed of testing is an issue, this built-in delay makes the pressure-decay method less desirable. More important, the two measurements and the time lapse significantly increase the potential for measurement error. The amount of time you need to wait between measurements varies. Sometimes, long intervals between measurements can make for extreme accuracy, but these long wait times are typically not practical. The larger the part volume, the longer it takes to measure the pressure drop. Moreover, very large flows are also impractical with pressure decay, because when pressure drops very fast, it will probably not be measured accurately.

Thus, although pressure-decay leak testing instruments have a relatively low upfront cost, the extra time it takes to perform testing (if the results are reliable enough for the given application) is another expense that needs to be factored in to overall cost. It can still be the best leak test method for a specific application, but the trend lines are in the other direction. Most applications now require tighter GR&R even for very low leak rates, often with large volume parts, and with a desire to keep test cycle times to the bare minimum to cut overall testing costs.When you factor all these considerations in, it often leads one to use other leak test methods instead.

In the upcoming issues of this “Leak Testing 101” series I will discuss differential pressure-decay testing, mass-flow leak testing, temperature compensation issues, and many other topics. By the conclusion of Leak Testing 101, my goal is to bring all quality managers up to speed on the real factors that affect leak testing cycle times, costs, and reproducibility.
