BRT-JZ50 Digital Pendulum Impact Tester

The BRT-JZ50 Digital Pendulum Impact Tester is a heavy-duty laboratory testing system engineered strictly in accordance with ISO 179, ISO 180, ISO 9854, ASTM D256, and GB/T 1043 standards. Designed for quality inspection laboratories, pipe manufacturing plants, university research centers, and polymer R&D institutes, it provides precise, highly repeatable evaluations of impact resistance, fracture toughness, and energy absorption across non-metallic materials, including rigid thermoplastics, reinforced nylon, glass-fiber composites, ceramics, and electrical insulation components.

Built with a high-rigidity steel frame structure that suppresses operational vibration, this dual-mode Pendulum Impact Tester supports both Charpy (simply supported beam) and Izod (cantilever beam) testing protocols. Guided by a digital control system and a high-resolution optical angle encoder, the BRT-JZ50 features a 3.8 m/s impact velocity, a standard 15J pendulum energy capacity (with interchangeable options), and an intuitive 7-inch LCD touchscreen interface that automatically calculates loss energy and displays impact strength in real time.

System Architecture & Applications of Pendulum Impact Tester

Standardized Testing Workflow:

1. Prepare notched or unnotched test specimens according to the specified standard (e.g., ISO 179 or ISO 180).
2. Install the appropriate Charpy anvils or Izod vise clamp onto the rigid machine base and secure the specimen.
3. Input the specimen dimensions (width, thickness, residual depth) into the 7-inch touchscreen controller.
4. Release the pendulum from its pre-set position; the hammer strikes the specimen at a standardized 3.8 m/s velocity.
5. The optical encoder measures the maximum rise angle on the swing-through, automatically calculates windage correction, and displays the net absorbed impact energy and impact strength.

Target Customer Applications:

• PVC-U, PE, PP, and composite pipe manufacturing plants and quality assurance labs.
• Engineering plastic compounding, reinforced nylon, and resin production facilities.
• Electrical insulation, ceramic component, and cast stone material testing labs.
• University polymer science departments, mechanical testing labs, and third-party inspection institutes.

Pendulum Impact Tester FAQ

Q1: Can the BRT-JZ50 perform both Charpy and Izod tests on the same machine?

A: Yes. The system control unit and frame architecture comply with both ISO 179/ISO 9854 (Charpy) and ISO 180/ASTM D256 (Izod) standards, allowing simple anvil and pendulum swaps for either test method.

Q2: What materials and specimen forms can be evaluated with this equipment?

A: It tests rigid plastic specimens, plastic pipes (PVC, PE, PP), engineering polymers, reinforced nylon, glass-fiber-reinforced composites, structural ceramics, cast stone, and electrical insulation products.

Q3: How does the digital optical encoder enhance test accuracy compared to dial gauges?

A: Dial gauges introduce mechanical drag and parallax reading errors. The digital optical encoder measures swing angle electronically without friction, allowing automatic subtraction of windage losses and instant calculation of precise energy absorption values.
