Jiubin JB-121C Tire Puncture Strength Tester

Overview

The Jiubin JB-121C Tire Puncture Strength Tester is an electromechanical universal testing machine engineered for standardized puncture energy evaluation of pneumatic tires in accordance with GB/T 4502 (Chinese National Standard for Tire Resistance to Puncture), ISO 10191 (Road Vehicles — Tyres — Test Methods for Puncture Resistance), and related regional specifications. It operates on the principle of controlled-force axial penetration using a calibrated plunger—typically 6 mm, 8 mm, or 12.7 mm in diameter—driven at a constant crosshead speed (e.g., 100 ± 10 mm/min) into the crown center of a mounted tire specimen. The system records real-time load vs. displacement data to calculate puncture energy (in joules), defined as the area under the force–displacement curve up to the point of complete penetration. Beyond tire-specific applications, the JB-121C complies with ASTM E4, ISO 7500-1, and JJG 475 calibration standards for general-purpose mechanical testing, supporting tensile, compression, flexural, shear, peel, and tear evaluations across metallic, polymeric, elastomeric, and composite substrates.

Key Features

• Electromechanical servo-controlled actuation with high-resolution load cell (±0.5% FS accuracy) and encoder-based displacement measurement (resolution ≤ 0.001 mm)
• Modular plunger kit accommodating standardized diameters (6 mm, 8 mm, 12.7 mm) for compliance with GB/T 4502, ISO 10191, and JIS D 4230 test protocols
• Adjustable crosshead speed range: 0.001–500 mm/min, programmable in 0.001 mm/min increments for precise strain-rate control
• Integrated safety interlocks including emergency stop, overload cutoff, and mechanical limit switches compliant with ISO 13857
• Stainless-steel test frame with 10 kN maximum load capacity and ≥ 800 mm vertical travel clearance for full-size passenger and light-truck tires
• Fully customizable test sequence logic and result reporting via embedded Windows-based control software

Sample Compatibility & Compliance

The JB-121C accommodates tire specimens ranging from motorcycle (10–12 inch rim diameter) to light-duty truck (up to 22.5 inch rim diameter), secured using adjustable clamping fixtures with pneumatic or manual locking. Non-tire applications include ASTM D638 (tensile), D790 (flexural), D1876 (peel), D624 (tear), and ISO 6892-1 (metal tensile) test configurations. All hardware and firmware meet CE marking requirements per Machinery Directive 2006/42/EC and EMC Directive 2014/30/EU. Calibration traceability is provided to CNAS-accredited national metrology institutes (e.g., SIMT, SGS Shanghai), with optional factory calibration certificates issued per ISO/IEC 17025.

Software & Data Management

The proprietary Jiubin TestMaster™ software—developed in-house by Jiubin’s certified software engineering team—is built on Microsoft .NET Framework and runs natively on Windows 10/11. Source code access is granted to end users under bilateral NDA, enabling full customization of test methods, pass/fail criteria, report templates (PDF/Excel), and data export formats (CSV, XML, JSON). The software supports audit trail logging per FDA 21 CFR Part 11 requirements (user authentication, electronic signatures, immutable event history), GLP/GMP-compliant data archiving, and seamless integration with LIMS platforms via OPC UA or RESTful API. Real-time graphing, statistical analysis (mean, SD, CV%), and multi-curve overlay are standard.

Applications

• Tire puncture resistance validation for OEMs and Tier-1 suppliers during R&D and production QA
• Material-level evaluation of tread compound toughness, carcass cord adhesion, and belt package integrity
• Comparative assessment of retreaded vs. new tire performance under standardized penetration conditions
• Mechanical property characterization of rubber compounds, thermoplastic elastomers, vulcanized composites, and reinforced polymers
• Quality conformance testing per customer-specific specifications (e.g., Ford WSS-M15P25-A, GMW14872, Toyota TSD1300G)
• Academic research in polymer mechanics, viscoelastic fracture, and dynamic impact response modeling

FAQ

Does the JB-121C comply with international tire puncture standards such as ISO 10191?
Yes—the system implements the prescribed plunger geometry, loading rate, and data acquisition resolution required by ISO 10191, GB/T 4502, and JIS D 4230.
Can the software be modified to support non-standard test methods?
Yes—source code access is included, allowing qualified personnel to develop custom test modules without licensing fees or vendor dependency.
Is calibration documentation provided with shipment?
Each unit ships with a factory calibration certificate traceable to national standards; optional ISO/IEC 17025-certified calibration is available upon request.
What is the maximum tire size the machine can accommodate?
The test chamber supports tires with rim diameters up to 22.5 inches and overall heights ≤ 1,100 mm when mounted on standard fixtures.
Does the system support automated reporting for regulatory submissions?
Yes—TestMaster™ generates 21 CFR Part 11-compliant reports with electronic signatures, version-controlled templates, and tamper-evident audit logs.
