Le ampoule three-point bending test is a critical procedure in the pharmaceutical and medical device industries, used to assess the breaking strength of ampoules. This test determines the force required to break an ampoule at its predetermined breaking point, ensuring that ampoules are robust enough to handle various handling conditions during transportation, storage, and use. In this article, we’ll explore the core aspects of the ampoule three-point bending test, ISO 9187 standards, and how specialized testers, like the Vial Ampoule Bottle Breaking Force Tester et Ampoule Breaking Strength Tester, help achieve accurate results.

What is the Ampoule Three-Point Bending Test?
Le ampoule three-point bending test involves applying a force to the ampoule’s constricted neck or stem to determine the breaking force required to rupture the glass. The test is designed to simulate the stress that the ampoule might experience during transportation or handling. Typically, a tensile testing machine equipped with specific fixtures is used to apply a force at a controlled rate to assess the breaking strength.
The ampoule is placed on a testing apparatus with two support points placed equidistant from the center. A force is applied from the middle of the ampoule to rupture it cleanly at the predetermined breaking point, often indicated by a ceramic ring or other notches.
ISO 9187: Standard for Ampoule Testing
Le ISO 9187 standard is crucial for ampoule testing, particularly for ISO 9187-1:2010 et ISO 9187-2:2010. These standards outline the requirements for testing ampoules’ force de rupture, annealing qualityet hydrolytic resistance. The standard ensures that ampoules meet specific criteria for breakage force, ensuring safety and reliability for injectable solutions.
ISO 9187-1:2010 specifies the testing process for ampoules, including details on the test machine’s setup, test speed, and force measurement accuracy. The standard stipulates the use of a tensile testing machine capable of applying a constant speed of 10 mm/min, with a force measuring range of 200 N.
ISO 9187 Break Force Tester
Le ISO 9187 break force tester is designed to perform the required tests to measure the force necessary to break an ampoule at its weakest point. The tester applies a controlled force to the ampoule until it fractures, recording the breaking force value.
This tester is essential for verifying whether the ampoule’s breaking strength falls within the specified limits of ISO 9187-1. Compliance with these standards is crucial for ensuring that the ampoule can withstand handling and transportation conditions without risk of premature breakage.
Vial Ampoule Bottle Breaking Force Tester
Le Vial Ampoule Bottle Breaking Force Tester is another specialized instrument designed for testing the breaking force of ampoules. It uses a similar methodology to the ampoule three-point bending test, but is specifically designed to test the strength of vials and ampoules used in pharmaceutical packaging.
This tester allows manufacturers to measure the force de rupture of ampoules, providing valuable data to ensure that the glass containers are durable enough for the safe storage and delivery of injectable medicines. The results of these tests help in determining the appropriate handling requirements for ampoules and minimizing the risks associated with glass breakage.
Key Steps in Conducting the Ampoule Three-Point Bending Test
- Préparation de l'échantillon: The ampoules are randomly selected and conditioned at a temperature of 20°C ± 5°C, ensuring consistency in testing conditions.
- Configuration du test: The ampoule is positioned on a tensile testing machine with two fixed points and the central force application point. The force is applied perpendicular to the axis of the ampoule.
- Application de la force: The testing machine applies the force at a controlled rate (10 mm/min), gradually increasing until the ampoule breaks. The force at which the ampoule fractures is recorded as the force de rupture.
- Results: The breaking force is compared to the specifications provided in ISO 9187 to ensure that the ampoule meets the required standards for strength and safety.
Benefits of the Ampoule Breaking Strength Tester
- Accurate Results: The Ampoule Breaking Strength Tester ensures that the force required to break the ampoule is measured precisely, providing reliable data for quality control.
- Standard Compliance: The tester helps manufacturers comply with ISO 9187 standards, which is essential for regulatory approvals in the pharmaceutical industry.
- Enhanced Safety: By testing ampoules for breaking strength, manufacturers can prevent issues related to breakage during handling or transportation, ensuring that injectable medications remain safe.
Conclusion
Le ampoule three-point bending test is a vital procedure for ensuring that ampoules used in the pharmaceutical industry are robust enough to withstand physical stress without breaking prematurely. By utilizing advanced testing equipment like the ISO 9187 break force tester et Vial Ampoule Bottle Breaking Force Tester, manufacturers can verify that their products meet essential standards for safety and performance. Adhering to ISO 9187 helps guarantee that ampoules maintain the required strength and reliability, providing a safe and effective solution for storing injectable medicines.
