Overview
The Yuelian YL-D25 Universal Testing Machine is an electromechanical static mechanical testing system engineered for high-reproducibility tensile, compression, flexural, shear, peel, tear, and adhesion evaluation of metallic, polymeric, composite, ceramic, textile, paper, and elastomeric materials. Based on closed-loop servo-controlled displacement and load regulation, the system implements a dual-feedback architecture—simultaneously monitoring load cell output and crosshead position—to ensure traceable force application and displacement fidelity across its full operational range. Designed in accordance with international metrological standards including ISO 7500-1 (Class 0.5) and ASTM E4 (Class I), the YL-D25 supports both routine quality assurance workflows and advanced material characterization under GLP-compliant environments.
Key Features
- High-precision load measurement with ±0.3% accuracy and 1/500,000 internal resolution, calibrated per ISO 7500-1 and traceable to national standards
- Programmable test speed from 0.01 to 1000 mm/min, enabling quasi-static to high-rate deformation studies without hardware modification
- Robust mechanical architecture featuring a preloaded precision ball screw, rigid C-frame construction, and low-backlash synchronous belt transmission
- Full PC-based control via proprietary software with real-time data acquisition at ≥1 kHz sampling rate and synchronized multi-channel analog input support
- Integrated safety logic including overload cutoff, emergency stop circuitry, specimen fracture auto-stop, and user-defined upper/lower displacement limits
- Dual-capacity load cell configuration option for extended dynamic range—e.g., simultaneous 500 N / 5 kN sensing without recalibration
- Comprehensive post-test analysis suite supporting ASTM/ISO/GB-defined parameters: tensile strength, yield strength (0.2% offset), Young’s modulus, elongation at break, flexural modulus, bending strength, peel strength, and tear resistance
Sample Compatibility & Compliance
The YL-D25 accommodates specimens ranging from thin films (≥0.05 mm thick) to structural metal coupons (up to 420 mm wide × 1200 mm travel). Standardized fixtures include wedge-action tensile grips, compression platens, three-point and four-point bend assemblies, 90° peel fixtures, and trouser-tear clamps—all conforming to dimensional tolerances specified in ASTM D638, ISO 527, ASTM D790, ASTM D6109, and GB/T 9341. The system meets regulatory requirements for instrument qualification under ISO/IEC 17025, supports 21 CFR Part 11-compliant electronic signatures when paired with validated software configurations, and provides full audit trail logging for GLP/GMP-aligned laboratories.
Software & Data Management
The embedded Windows-compatible software delivers ISO 17025-aligned data integrity through timestamped, user-authenticated test records stored in encrypted MS-ACCESS databases. Functions include automated standard selection (GB, ASTM, ISO, JIS, DIN), customizable report templates with embedded calibration certificates, real-time stress–strain curve overlay, batch statistical summaries (mean, SD, CV%), and export to CSV, PDF, or XML formats. All raw data—including load, displacement, time, and auxiliary sensor inputs—is retained with metadata (operator ID, environmental conditions, calibration date, fixture ID) to satisfy FDA and CNAS traceability mandates.
Applications
This system serves as a foundational platform for mechanical property validation across R&D, QC, and incoming inspection workflows. Typical use cases include: tensile characterization of aerospace aluminum alloys per AMS 4027; flexural testing of thermoset composites per ASTM D7264; peel strength assessment of pressure-sensitive adhesives per ASTM D3330; tear propagation resistance of rubber compounds per ISO 34-1; compressive yield behavior of biomedical polymers per ISO 604; and interlaminar shear strength of CFRP laminates per ASTM D2344. Its modular design allows seamless integration into automated test lines via digital I/O and Ethernet/IP protocols.
FAQ
Does the YL-D25 comply with ISO 17025 method validation requirements?
Yes—the system supports documented IQ/OQ/PQ protocols, includes built-in calibration verification routines, and retains full traceability logs for all critical parameters.
Can the software generate CFR Part 11-compliant reports?
When deployed with validated installation packages and role-based access controls, the software meets electronic record and signature requirements under 21 CFR Part 11.
Is third-party calibration certification available?
Certified calibration services with NIST-traceable documentation are offered through authorized Yuelian service centers in APAC and EU regions.
