Labthink FIT-01 Film Pendulum Impact Tester

Overview

The Labthink FIT-01 Film Pendulum Impact Tester is a precision-engineered instrument designed to quantify the energy absorption capacity of thin, flexible polymeric and metallic sheet materials under controlled dynamic loading conditions. Operating on the principle of pendulum impact mechanics—where a calibrated hemispherical striker, released from a defined height, strikes a horizontally clamped specimen—the system measures the residual kinetic energy after penetration. The difference between initial potential energy and post-impact residual energy yields the absorbed impact energy (in joules), providing a quantitative metric of film toughness, ductility, and resistance to brittle fracture. This method aligns with classical Charpy-style impact testing adapted for low-mass, high-flexibility substrates, making it essential for quality control in packaging R&D, medical device barrier layer validation, and functional film development.

Key Features

• Three selectable nominal impact energies (1 J, 2 J, 3 J) achieved via interchangeable calibrated pendulum masses and optimized lift-height calibration—ensuring traceable energy delivery per ISO 179-1 and ASTM D3420 Annex A.
• Modular hemispherical impactor set (Φ25.4 mm, Φ19 mm, Φ12.7 mm) enables standardized and application-specific probe geometry selection, supporting both regulatory compliance and material differentiation studies.
• Pneumatically actuated specimen clamping (0.6 MPa required) eliminates manual torque variability; combined with motor-assisted pendulum release and automated horizontal alignment verification, it minimizes operator-induced measurement uncertainty.
• High-resolution load cell (0.001 J resolution) integrated into the pendulum shaft delivers direct energy measurement without reliance on angular displacement interpolation—enhancing repeatability across laboratories.
• Microprocessor-based control architecture with backlit LCD interface, tactile PVC membrane keypad, and intuitive menu navigation ensures rapid setup and real-time test monitoring without external software dependency.
• Integrated thermal-printed report output and RS232 serial interface support immediate documentation and seamless integration into LIMS or enterprise QA databases.

Sample Compatibility & Compliance

The FIT-01 accommodates planar specimens up to 100 mm × 100 mm or Ø100 mm, including plastic films (LDPE, PET, BOPP), metallized laminates, aluminum foils, coated paperboard, and multilayer barrier composites. Dual-diameter anvil fixtures (Ø89 mm and Ø60 mm) permit adaptation to varying stiffness ranges while maintaining consistent boundary constraints. The instrument conforms to GB/T 8809–1988 (Chinese national standard for plastic film impact resistance), ASTM D3420–2013 (Standard Test Method for Impact Resistance of Plastic Film by Pendulum Method), and NF T54-116 (French standard for flexible packaging impact performance). Its mechanical design and energy calibration protocol support GLP-compliant operation when paired with documented calibration certificates and audit-trail-enabled software modules.

Software & Data Management

The base system includes embedded firmware for automatic data acquisition, statistical calculation (mean, SD, CV%), and on-screen result visualization. Optional Lystem™ Laboratory Data Sharing System enables centralized storage, role-based access control, electronic signature capability, and 21 CFR Part 11–compliant audit trails—including user action logs, parameter change history, and raw sensor timestamping. Export formats include CSV, PDF, and XML for traceability in GMP-regulated environments. All firmware updates are delivered via secure HTTPS channel with cryptographic integrity verification.

Applications

• Quality assurance of food, pharmaceutical, and medical packaging films during incoming inspection and process validation.
• Comparative evaluation of impact resistance across resin grades, additive formulations (e.g., impact modifiers), and coextrusion layer architectures.
• Accelerated aging studies—measuring embrittlement onset after UV exposure, thermal cycling, or humidity conditioning.
• Regulatory submission support for FDA 510(k) dossiers requiring mechanical durability evidence of pouch seal integrity.
• R&D screening of nanocomposite films, biodegradable substrates, and ultra-thin barrier coatings where traditional tensile or puncture tests lack sensitivity.

FAQ

What standards does the FIT-01 comply with?

The instrument meets GB/T 8809–1988, ASTM D3420–2013, and NF T54-116 requirements for pendulum impact testing of flexible sheet materials.
Is calibration certification included with shipment?

Yes—each unit ships with a factory-issued calibration certificate traceable to NIM (National Institute of Metrology, China), covering energy scale, impactor geometry, and sensor linearity.
Can the FIT-01 be integrated into a networked laboratory environment?

Absolutely—via RS232 or optional Ethernet module, it supports bidirectional communication with Lystem™, LabWare LIMS, or custom MES platforms using ASCII/Modbus RTU protocols.
What pneumatic supply specifications are required?

A clean, dry compressed air source at 0.6 MPa ±0.05 MPa, connected via Ø6 mm polyurethane tubing, is mandatory. An inline filter-regulator-lubricator (FRL) unit is recommended for long-term sensor protection.
Are non-standard impactor geometries available?

Yes—custom hemispherical or flat-tipped impactors (e.g., Ø6 mm, Ø10 mm, conical profiles) can be fabricated and certified upon request, subject to mechanical compatibility verification.
