Leak Test Simplified: Standardized Vacuum Testing with Model M
How perform leak tests in seconds without relying on a complex system?
Many companies perform leak integrity tests on packages or containers…
But often using systems that generate variable results, depend heavily on the operator, or introduce unnecessary complexity.
In this article, we’ll explain a much more practical way to perform leak testing according to ASTM D3078. And how to determine when a simplified vacuum system is the right solution for your process.
In this tutorial, you’ll learn:
- The easiest way to perform reliable, repeatable and affordable tests.
- How to decide when this type of system is appropriate?
Standards mentioned
ASTM D3078 – Standard Test Method for Determination of Leaks in Flexible Packaging by Bubble Emission.
ASTM D6653 – Standard Test Methods for Determining the Effects of High Altitude on Packaging Systems by Vacuum Method.
ASTM E515 – Standard Test Methods for Leak Using Bubble Emission Techniques.
The problem with many leak testing systems
In practice, many companies struggle with:
❌ Inconsistent vacuum levels
❌ Operator-dependent results
❌ Complex interfaces or configurations
❌ Difficult standardization across multiple test stations
These issues directly affect repeatability and reliability, which are critical in ASTM-compliant testing.
Imagine being able to perform leak tests in seconds—no menus, no configurations, no dependence on a complex system.
That’s exactly what this system enables. Direct control, where every action is immediate… without sacrificing consistency in the results.
The Model M is a control system compatible with any CDV Vacuum Chamber.
That means you can choose the chamber size you need… and use the same control module.
This translates into something very concrete:
A standardized system—even if your facility has vacuum chambers of different sizes.
One single operating logic across your entire site.
And above all, an accessible solution that lets you start with a controlled investment, without giving up process reliability.
This is where many people make a mistake:
They assume that a simple system means losing control or precision. In reality, this module is designed to deliver repeatable and reliable results in every test.
The vacuum level is adjusted using a manual valve, with a direct reading on the vacuum gauge.
But it also integrates an air bleed system that allows the test vacuum level to be set repetitively.
This system is preset to the value you need… and locked with a locknut, preventing accidental adjustments. To change it, a tool is required.
In practice, this allows you to achieve the same vacuum level every time, regardless of the operator.
The operator simply actuates the valve… and the system does the rest. Consistent results, without complexity.
Digital vacuum gauge
This system includes a digital vacuum gauge. We know there are more affordable analog options, but their readings can be less reliable and more susceptible to damage.
Here, the reading is clear, direct, and unambiguous. You see the exact vacuum value at all times.
This system allows you to perform leak tests in accordance with standards such as ASTM D3078, as well as other methods that require testing in a vacuum chamber.
Is this system appropriate for your processes?
You can run dry tests or immersion tests, identifying leaks visually. It also allows you to simulate atmospheric pressure variations, replicating real transportation or storage conditions.
This type of system is ideal when you’re looking for a practical, reliable solution aligned with your current budget.
But if your process requires automation, traceability, or data management… then you will need a more advanced system.
You don’t have to decide everything from the start. You can begin with this module… and evolve later without changing your chamber. You simply replace the control system.
If you’re wondering whether this system is sufficient for your application… That’s exactly the conversation we should have.
