The charpy izod impact tester (BT-PIT Series) manufactured by Bayerteq is an advanced pendulum impact testing instrument designed to evaluate the dynamic fracture toughness, impact resilience, and notch sensitivity of rigid thermoplastics, engineering polymers, and pipe materials. Engineered in full compliance with international standards including ISO 179, ISO 180, ASTM D256, and ASTM D6110, this instrument delivers high-repeatability shock characterization for raw resin producers, compounding facilities, and quality control laboratories.
Polymeric components in automotive, aerospace, piping, and consumer applications must resist rapid physical shocks without catastrophic shattering. The Bayerteq charpy izod impact tester subjects standardized notched and unnotched test specimens (80 × 10 × 4 mm) to high-speed dynamic bending strikes, accurately quantifying the exact energy absorbed during specimen rupture.
Charpy Izod Impact Tester Configurations & Energy Classes
The BT-PIT series integrates versatile clamping fixtures and interchangeable calibrated hammers to accommodate standard and high-impact polymers:
- Dual Charpy & Izod Testing Modes: Rapidly switch between 3-point beam Charpy bending support anvils and vertical cantilever Izod clamping vices using precision quick-positioning alignment fixtures.
- Multi-Tier Calibrated Pendulums: Standard configurations feature 1.0 J, 2.75 J, and 5.5 J hammer heads, with heavy-duty extended configurations (Model BT-CH-50) delivering high-energy capacities of 11.0 J, 22.0 J, 25.0 J, and 50.0 J for reinforced composites and tough polyolefins.
- Photoelectric Non-Contact Angle Encoder: Delivers ±0.1% measurement accuracy with 0.001 J display resolution, capturing real-time pendulum release and follow-through rebound angles without mechanical drag.
- Automated Energy Loss Compensation: Proprietary firmware automatically measures and subtracts aerodynamic air resistance and bearing friction losses (1.0 J: 2%, 2.75 J: 1%, 5.5 J: 0.5%), guaranteeing pure net specimen rupture energy calculations.
- Integrated Touchscreen & Data Management: An industrial touchscreen computer guides operators through standardized test sequences, automatically calculates impact strength in kJ/m² or J/m, and exports data via USB.
Every Bayerteq charpy izod impact tester features a heavy cast-iron vibration-damped base, transparent interlocked protective safety shields, and CE compliance for maximum laboratory protection.
