Overview
The Yuelian YL-1161 High-Low Temperature Universal Testing Machine is an electromechanical static materials testing system engineered for precision mechanical property characterization across extreme thermal conditions. It operates on a dual-actuator servo-controlled architecture, integrating a high-rigidity load frame with a certified environmental chamber capable of stable operation from –70 °C to +300 °C. The system implements force-controlled, displacement-controlled, and strain-controlled test modes in accordance with standardized quasi-static loading protocols defined in ASTM E4 (load verification), ASTM E8/E21 (tensile and elevated-temperature testing), ISO 6892-1 (metallic materials tensile testing at ambient temperature), and ISO 7500-1 (static calibration of force-measuring systems). Its modular design supports interchangeable load cells (ranging from 100 N to 50 kN full scale), extensometers (contact and non-contact), and gripping solutions—enabling reproducible measurement of tensile strength, yield point, elongation at break, modulus of elasticity, compressive yield stress, flexural modulus, peel adhesion, and fatigue initiation thresholds under thermally constrained conditions.
Key Features
- Integrated high-fidelity environmental chamber with independent PID-controlled refrigeration and heating circuits, achieving ±0.5 °C temperature uniformity over 150 mm × 150 mm × 200 mm test volume
- Servo-motor-driven crosshead with 0.001 mm positioning resolution and closed-loop feedback via linear encoder
- Load cell accuracy compliant with ISO 7500-1 Class 0.5 (±0.5% of reading from 1% to 100% FS)
- Modular grip interface supporting wedge-action, pneumatic, hydraulic, and custom fixtures—including low-temperature cryo-grips rated to –70 °C
- Real-time data acquisition at up to 10 kHz sampling rate, synchronized with thermal chamber telemetry (temperature, ramp rate, dwell stability)
- Frame stiffness ≥ 250 kN/mm to minimize compliance error during high-force compression and creep testing
Sample Compatibility & Compliance
The YL-1161 accommodates standard and non-standard specimens per ASTM D638 (plastics), ASTM D3039 (composites), ISO 527-2 (thermoplastics), ISO 178 (flexural testing), and ISO 1133 (melt flow index correlation studies). Specimen geometries include dog-bone, straight-bar, disc, film, fiber bundles, and adhesive lap joints. All test configurations are traceable to national metrology institutes (NIM, CNAS-accredited labs) and support GLP/GMP documentation workflows. The system meets mechanical safety requirements per ISO 12100 and electrical safety per IEC 61000-6-2/6-3. Optional audit trail modules enable 21 CFR Part 11–compliant electronic records for regulated pharmaceutical and biomedical material qualification.
Software & Data Management
Control and analysis are executed via Yuelian TestSuite v4.2—a Windows-based platform supporting multi-channel real-time plotting, automatic test sequence scripting (ASTM/ISO pre-sets), and post-test parameter extraction (e.g., offset yield, tangent modulus, fracture energy). Raw data exports in .csv, .xlsx, and universal .tdms formats; metadata embedding includes operator ID, calibration certificate IDs, environmental chamber log headers, and instrument firmware version stamps. The software integrates with LIMS environments through OPC UA and supports automated report generation aligned with ISO/IEC 17025 technical record requirements.

FAQ
Does the YL-1161 comply with ISO 17025 calibration requirements?
Yes—the system’s load cell, displacement transducer, and temperature sensor chains are supplied with factory calibration certificates traceable to NIM, and third-party verification services are available for ISO/IEC 17025 accreditation.
Can the machine perform constant strain-rate tests per ASTM D638?
Yes—it supports user-defined strain-rate profiles (e.g., 1 mm/min to 500 mm/min) with real-time feedback compensation for thermal expansion-induced dimensional drift.
Is remote monitoring supported during extended temperature dwell tests?
Yes—via Ethernet-connected embedded controller with HTTPS-enabled web interface for live status, alarm logging, and emergency stop initiation.
What extensometer options are compatible with sub-zero testing?
Contact-type clip-on extensometers with Invar arms and cryo-rated strain gauges (–70 °C to +150 °C), as well as non-contact digital image correlation (DIC) systems with heated lens housings, are validated for integration.
How is mechanical alignment verified after chamber installation?
The system includes a laser collimation kit and alignment verification procedure per ASTM E1012, ensuring axial misalignment remains below 0.02 mm/m prior to certification testing.
