Norma NF T54-116
Film Pendulum Impact Testing
Impact resistance is one of the most important performance metrics for flexible plastic films used in packaging, medical devices, and industrial applications. The film pendulum impact tester plays a crucial role in evaluating how well a film withstands sudden mechanical force. The Norma NF T54-116 standard, a widely adopted French norm, provides a detailed method—often referred to as the perforamètre method—to quantify the pendulum impact resistance of plastic film through controlled testing.
This article will guide you through the essentials of Norma NF T54-116, explore its relationship with international ASTM standards for impact testing of plastics, and recommend the advanced Probador de impacto de péndulo PIT-01 de Instrumentos celulares, a reliable solution for quality assurance teams and R&D labs worldwide.
Key Test Standards
El Norma NF T54-116 standard specifies a test method that determines the film impact resistance by measuring the energy required to puncture a plastic sheet using a pendulum arm fitted with a hemispherical impact head. It’s comparable to the globally recognized ASTM D3420 standard, which evaluates the pendulum impact resistance of plastic film using similar principles. The Spencer impact test is another related method used widely in North America and serves as a benchmark for spencer impact testing equipment.
While each standard varies slightly in specimen preparation, energy scales, and clamping mechanisms, they all aim to quantify the impact resistance of plastic film in repeatable and precise ways.
The Principle Behind NF T54-116
El pendulum shock test described in NF T54-116 involves:
A plastic film specimen (typically 100×100 mm or Ø100 mm) clamped firmly using a pneumatic system.
A pendulum with a hemispherical impactor (commonly Ø38.1 mm) swings from a fixed angle.
Upon striking the specimen, the pendulum’s residual energy is measured and subtracted from the initial potential energy.
El absorbed energy (in joules) is recorded, representing the film’s resistance to puncture or tear.
Energy values are then normalized to the sample’s thickness to ensure consistency across material types.
This method is especially useful for testing flexible packaging films, laminates, barrier materials, and even medical pouches, where puncture failure is a critical concern.
Aplicaciones y beneficios
Understanding the pendulum impact resistance test is essential in sectors such as:
Embalaje: Prevents packaging failures during handling and transport.
Farmacéutico: Ensures drug pouches and blister films remain intact.
Alimentos y bebidas: Verifies the robustness of vacuum and sealable films.
Dispositivos médicos: Validates sterile barrier integrity under stress.
Benefits of this method include:
Quantitative comparison of materials during product development.
Rapid quality checks during mass production.
Compliance with astm standards for impact testing of plastics and global norms.
How to Conduct a Film Impact Resistance Test
1. Prepare the Specimens
Cut ten specimens to the required size (100×100 mm) and condition them at 23°C ± 2°C for at least 2 hours.
2. Select Test Parameters
Choose an appropriate impact head and counterweight based on material strength. Ensure that energy absorption falls within 10–80% of the full scale.
3. Perform the Test
Secure the specimen using pneumatic clamps. Release the pendulum, allowing it to strike the center of the sample.
4. Record Results
Read absorbed energy from the dial. Note whether the specimen exhibits brittle or ductile failure.
5. Report Findings
Include energy values (J), normalized by specimen thickness (µm), average, standard deviation, and qualitative observations like perforation appearance.
