Overview
The ZHENHUAFENXI SKZ-1000B Digital Flexural Strength Tester is a precision-engineered universal bending testing system designed specifically for the mechanical characterization of brittle and quasi-brittle ceramic materials. It operates on the three-point or four-point bending principle—where a rectangular specimen is supported at two points and loaded centrally (or at two symmetric points)—to determine flexural strength (modulus of rupture) and load-deflection behavior in accordance with standardized test protocols. The instrument employs a motor-driven loading actuator with closed-loop force control to ensure consistent, linearly increasing load application across the full specified range. Its structural rigidity, calibrated load cell integration, and low-drift signal conditioning enable high reproducibility in measurements required for quality assurance, R&D validation, and regulatory compliance in ceramic manufacturing and construction material laboratories.
Key Features
- Motorized, programmable loading mechanism delivering precise force application from 5 to 700 N/s, fully adjustable via front-panel controls or optional PC interface
- Dual-range high-accuracy load cell options (1 kN, 5 kN, 10 kN, 20 kN) with traceable calibration certificates compliant with ISO 7500-1 Class 1 requirements
- Modular support and loading fixture system enabling rapid reconfiguration for diverse specimen geometries—from small laboratory tiles (50 × 60 mm) to large-format architectural ceramics (up to 1200 × 1200 mm)
- Integrated digital display unit providing simultaneous real-time readouts of applied load (kN), peak load (kN), and current loading rate (N/s)
- Onboard data logging with automatic peak capture, timestamping, and export-ready output compatible with CSV and Excel formats
- Robust steel frame architecture with precision-ground support rollers and hardened steel loading anvils to minimize deformation under high-load conditions
Sample Compatibility & Compliance
The SKZ-1000B is validated for use with a broad spectrum of rigid, non-metallic building and industrial ceramics—including glazed and unglazed ceramic tiles, porcelain stoneware, roof tiles, concrete roofing units, asbestos-cement corrugated sheets, natural stone slabs, fiber-cement panels, and gypsum board. It satisfies the mechanical testing requirements of multiple international and national standards: GB/T 3810.4–2016 (equivalent to EN ISO 10545-4) for ceramic tile flexural strength; GB/T 36584–2018 (roof tile flexure); JC 746–2007 (concrete tile load-bearing capacity); GB/T 9772–1996 (asbestos-cement roofing); GB/T 9966.1–2001 (natural stone flexure); GB/T 7019–1997 (fiber-cement products); and GB/T 9775–1999 (gypsum board). All test configurations adhere to standard span-to-depth ratios and support conditions defined in respective normative annexes.
Software & Data Management
While the SKZ-1000B operates as a standalone instrument with embedded firmware, it supports optional USB or RS-232 connectivity for integration with Windows-based data acquisition software. This software enables user-defined test sequences, real-time graphical plotting of load vs. time/deflection curves, statistical analysis of batch results (mean, SD, CV%), and generation of audit-ready reports compliant with GLP and ISO/IEC 17025 documentation requirements. Raw data files include metadata such as operator ID, calibration date, environmental temperature (if external sensor enabled), and test standard reference—facilitating traceability during internal audits or third-party certification assessments.
Applications
- Quality control of ceramic tile production lines per ISO 10545-4 and GB/T 3810 series
- Evaluation of flexural performance of roofing systems under static and simulated wind-load conditions
- Comparative assessment of reinforcement efficacy in fiber-cement composites
- Mechanical screening of new glaze formulations and firing schedules for fracture resistance
- Validation of dimensional stability and structural integrity of large-format porcelain slabs used in façade applications
- Research into moisture-induced strength degradation in clay-based masonry units
FAQ
What standards does the SKZ-1000B directly support without hardware modification?
It natively complies with GB/T 3810.4–2016, EN ISO 10545-4, GB/T 36584–2018, and JC 746–2007 using standard three-point bending fixtures.
Can the instrument perform compression tests?
No—it is optimized for flexural testing only; compressive strength evaluation requires dedicated compression testing machines meeting ASTM C109 or ISO 7500-1 requirements.
Is the loading rate programmable in closed-loop mode?
Yes—rate control is achieved via feedback from the load cell and motor encoder, ensuring linearity within ±2% of setpoint across the 5–700 N/s range.
Does the system meet FDA 21 CFR Part 11 requirements?
The base configuration does not include electronic signature or audit trail functionality; however, the optional PC software package can be configured for Part 11 compliance upon customer specification and validation support.
What maintenance intervals are recommended for long-term accuracy?
Annual recalibration of the load cell and verification of roller alignment are advised; daily visual inspection of anvil surfaces and periodic lubrication of drive components are included in the operator manual.
