ASTM F2095 + ASTM F2054: How We Turned a Special Testing Requirement into a Combined Test Solution
Can your package pass an internal pressurization test and a burst test in a single protocol?
In this post, we explain how ASTM F2095 and ASTM F2054 can be combined into a single protocol to evaluate both leak integrity and burst strength in flexible packages.
Standards mentioned
ASTM F2095 – Standard test method for detecting leaks in packages by internal pressurization and pressure decay
ASTM F2054 – Standard test method for burst testing flexible packages using internal pressurization with restraining plates
ASTM F2096 – Standard test method for detecting gross leaks in packages by bubble emission
ASTM D3078 – Standard test method for determination of leaks in flexible packages by bubble emission
How We Turned a Special Testing Requirement into a Combined Test Solution
During a laboratory test, a flexible package exploded with such force that it damaged part of the equipment we were using. It was not an accident. It was part of the process. We were developing a special application that led us to combine two ASTM methods into a single test protocol: a leak integrity test and a burst test for flexible packages.
ASTM F2095
Leak detection by internal pressurization and pressure decay
ASTM F2054
Burst testing with restraining plates
The objective was clear: pressurize the package to verify its leak integrity and then increase the pressure in a controlled way to evaluate whether the seal could withstand the conditions defined by the customer.
A Protocol with Two Critical Stages
The proposed test was divided into two main phases.The proposed test was divided into two main phases.The proposed test was divided into two main phases:
First, the package had to be pressurized to 5 PSI for a defined period of time to detect possible leaks through pressure decay.
Then, the pressure increased at 1 PSI per second until reaching 25 PSI to evaluate seal strength.
Although the principle seemed straightforward, the system development presented important challenges. At that time, DVACI did not officially offer this application. Our equipment was mainly used for tests such as ASTM F2096 or ASTM D3078, but internally we were already exploring how to adapt our technology for this type of combined test.
During development, early solutions showed mechanical limits, so we tested above 50 PSI to understand the system’s real behavior and operating limits.
These tests allowed us to adjust the design, improve the configuration, and develop a more reliable solution for applications where internal pressure and seal strength are critical factors.
The Final Solution CDV4 with Model P control System
After the development process, we implemented a solution based on a CDV4 equipped with a Model P control system, specifically adapted for this application.
This project was carried out in collaboration with our U.S. distributor, Thwing Albert, and allowed us to integrate leak integrity and seal strength evaluation into a single testing approach.
This project reminded us of something fundamental: many innovations begin with a simple question from a customer.
A specific need can become the starting point for developing new applications, adapting existing technologies, and creating more complete solutions for package validation.
At DVACI, we work with manufacturers, laboratories, and quality teams that need to evaluate leaks, airtightness, seal integrity, and package behavior under pressure.
