ISO 9187
En ISO 9187 prueba de resistencia a la rotura de la ampolla is designed to measure the fuerza de rotura of glass ampoules with predetermined breaking points. By applying a controlled mechanical force and recording the value required to achieve fracture, manufacturers can verify whether ampoules provide a safe and reliable opening experience.
Ampoule Break Strength Testing
Glass ampoules are widely used in pharmaceutical packaging because they provide excellent protection for sterile injectable products. However, the opening performance of an ampoule directly affects user safety, dosage integrity, and contamination prevention. ISO 9187 provides standardized requirements for evaluating ampoule opening characteristics, especially the force required to separate the ampoule stem from the body.
For pharmaceutical companies, packaging manufacturers, and quality control laboratories, accurate break-force measurement helps ensure that ampoules are neither too difficult to open nor too fragile during handling and transportation.

Why ISO 9187 Ampoule Break Strength Testing Is Important for Pharmaceutical Packaging
The performance of a glass ampoule neck is a critical quality parameter. An ampoule must maintain sufficient mechanical strength during storage, transportation, and sterilization, while still allowing healthcare professionals to open it safely.
A properly controlled prueba de resistencia a la rotura de la ampolla helps manufacturers evaluate:
- Opening force consistency between production batches
- Risk of excessive force causing hand injuries
- Possibility of glass fragments entering the medication
- Stability of the predetermined breaking point
- Compliance with pharmaceutical packaging requirements
According to ISO 9187, the test determines the force needed to separate the ampoule stem from the body and evaluates whether a clean break occurs. The standard focuses on measurable mechanical performance rather than subjective opening evaluation.
Ampoule Break Strength Test and 3 Point Bending Test Principle
En Prueba de flexión en 3 puntos is a commonly applied mechanical method for evaluating the fracture behavior of glass ampoules. During the test, the ampoule is positioned with suitable supports, and a controlled force is applied at a specific location near the constriction area.
The basic principle includes:
- Positioning the ampoule correctly using suitable fixtures.
- Applying force perpendicular to the ampoule axis.
- Increasing the load until the neck breaks.
- Recording the maximum force required for fracture.
The measured value represents the fuerza de rotura, which indicates the mechanical resistance of the ampoule neck.
ISO 9187 specifies that the test should use controlled conditions, including appropriate equipment accuracy, sample conditioning, and test speed. A tensile testing machine or equivalent mechanical testing system can be used, with a recommended test speed of 10 mm/min and a suitable force measurement range.
The test is suitable for ampoules with predetermined breaking points, such as ceramic rings or other designed fracture areas.
Ampoule Break Strength Test and 3 Point Bending Test Principle
En ISO 9187 ampoule break strength test is mainly applied to glass ampoules used for injectable pharmaceutical products. Typical applications include:
Pharmaceutical ampoules
Used for sterile liquid medicines, vaccines, and injectable formulations where packaging reliability is essential.
Glass container manufacturers
Used during product development and production quality control to verify neck design and fracture performance.
Laboratorios de control de calidad farmacéutica
Used for incoming inspection, batch verification, and regulatory compliance testing.
Packaging development departments
Used to optimize glass thickness, scoring design, and opening characteristics.
The test is especially valuable because small changes in glass forming processes or breaking-point design can significantly affect opening force.
Cell Instruments BST-01 for ISO 9187 Ampoule Breaking Force Testing
To perform reliable ISO 9187 ampoule break strength testing, laboratories require equipment that provides accurate force measurement and stable mechanical control. The Cell Instruments BST-01 Ampoule Breaking Tester is designed specifically for quantitative evaluation of ampoule breaking force.
The BST-01 measures the force required to break the ampoule neck and supports quality evaluation of pharmaceutical glass packaging. It provides a test range of 0–200 N, adjustable testing speed, and high-resolution force measurement for repeatable results.
The instrument follows the ISO 9187 testing concept by applying controlled force until fracture and recording the peak breaking value. Its test process includes selecting suitable fixtures, mounting ampoules, setting test speed, and recording maximum breaking force data.
Key advantages include:
- High-precision load measurement for accurate breaking force evaluation
- Adjustable testing speed to support different ampoule requirements
- Interchangeable fixtures suitable for multiple ampoule capacities
- Protective structure to improve operator safety during glass fracture testing
- Digital data display and reporting capability for quality control management
The BST-01 supports ampoules from different capacities and helps pharmaceutical manufacturers improve consistency in packaging verification.
FAQs
Q1: What is the purpose of the ISO 9187 ampoule break strength test?
En ISO 9187 ampoule break strength test evaluates the force required to separate the stem from the body of a glass ampoule with a predetermined breaking point. The test helps pharmaceutical manufacturers confirm that ampoules can be opened safely while maintaining sufficient mechanical strength during storage and transportation.
Q2: What type of ampoules can be tested according to ISO 9187?
ISO 9187 applies mainly to glass ampoules used for pharmaceutical packaging, especially ampoules with designed breaking points, such as ceramic ring-marked ampoules. These containers are commonly used for sterile injectable products and other liquid pharmaceutical formulations.
Q3: What is measured during an ISO 9187 test?
The main parameter measured is the fuerza de rotura, which represents the maximum force required to fracture the ampoule neck and separate the ampoule stem from the body. The test also helps evaluate whether the ampoule produces a clean break after fracture.
Q4: Is ISO 9187 testing the same as a 3 point bending test?
Q5: What test conditions are required for ISO 9187?
According to ISO 9187, samples should be conditioned at approximately 20 °C ± 5 °C before testing. The testing equipment should provide controlled force application, with a recommended test speed of 10 mm/min and suitable force measurement capability.A5: By providing precise break force measurements aligned with pharmacopoeia standards, it helps manufacturers meet regulatory approval requirements.
