Yuelian YL-1163 Environmental Chamber-Integrated Tensile Testing Machine

Overview

The Yuelian YL-1163 Environmental Chamber-Integrated Tensile Testing Machine is an electromechanical universal testing system engineered for high-fidelity mechanical property evaluation under precisely controlled climatic conditions. Unlike conventional tensile testers limited to ambient environments, the YL-1163 integrates a fully programmable temperature-humidity chamber—designed and validated per ISO 23718 and ASTM D4329—directly into the load frame architecture. This enables real-time, synchronized application of uniaxial tensile, compressive, flexural, shear, tear, peel, and delamination loads while maintaining stable thermal-hygrometric profiles across −70°C to +150°C and 20–98% RH. The system operates on a closed-loop servo-controlled drive train with precision ball screw transmission, delivering sub-micron positional repeatability and force linearity compliant with ISO 7500-1 Class 0.5 accuracy requirements. Its modular chamber design allows rapid detachment for standalone high-speed mechanical testing (up to 500 mm/min), optimizing lab space utilization without compromising environmental test integrity.

Key Features

• Modular dual-mode operation: Integrated environmental chamber for climate-dependent testing; removable chamber for high-throughput ambient-mode mechanical characterization.
• Programmable environmental control via YL-C201 controller: Supports 120 stored test profiles, 1200-segment ramp/soak sequences, up to 999 total cycles, and nested loop structures with independent time and setpoint resolution (0.1°C / 0.1% RH).
• High-resolution force measurement: 1/250,000 internal resolution with ≤±0.5% full-scale accuracy traceable to NIST-traceable calibration standards.
• Adaptive PID temperature/humidity regulation: Fan-forced air circulation, surface-evaporation humidification with dry-run protection, refrigerant-based dehumidification (eco-friendly R134a), and SUS304-sheathed heating elements ensure thermal stability within ±1°C and humidity stability within ±2.5% RH.
• Comprehensive safety architecture: Dual-stage thermal cutoffs (heater, humidifier, compressor), ground-fault circuit interruption, overload tripping, emergency stop with hardware interlock, and automatic specimen rupture halt with position hold.
• Full PC-based test management: Windows-compatible software with MS Access database backend, multi-sensor synchronization (load, displacement, temperature, humidity), real-time curve overlay, ASTM/ISO-compliant report generation, and audit-ready data export (CSV, PDF, XML).

Sample Compatibility & Compliance

The YL-1163 accommodates standard and custom specimens—including films, fibers, elastomers, composites, adhesives, packaging laminates, biomedical polymers, and textile substrates—within its 600 mm wide × 1200 mm stroke envelope (chamber removed) or 40×80×40 cm conditioned volume (chamber installed). It supports standardized test fixtures per ASTM D882 (thin plastics), ASTM D638 (tensile bars), ASTM D1876 (peel), ISO 1133 (melt flow index correlation), and ISO 527 (tensile properties of plastics). All electronic subsystems comply with IEC 61000-4 electromagnetic compatibility directives; mechanical load frame construction adheres to ISO 7500-1 static calibration protocols. Software functionality meets FDA 21 CFR Part 11 requirements for electronic records and signatures when configured with user access controls, audit trail logging, and electronic signature workflows.

Software & Data Management

The embedded YL-TS2020 test control software provides a deterministic real-time acquisition layer interfacing directly with the system’s 24-bit ADC and motion controller. It supports concurrent sampling of force, displacement, chamber temperature, and relative humidity at ≥1 kHz rates, with timestamped metadata embedding environmental setpoints and deviations. Data is stored in encrypted binary format with optional MS Access relational database integration for cross-test statistical analysis (e.g., ANOVA of modulus vs. RH level). Reporting modules generate ISO/IEC 17025-aligned certificates—including uncertainty budgets per GUM (Guide to the Expression of Uncertainty in Measurement)—and support GLP/GMP-compliant audit trails with immutable event logs (user login/logout, parameter changes, calibration events, test start/stop). Remote monitoring and programming are enabled via Ethernet TCP/IP interface with secure SSH tunneling options.

Applications

• Evaluation of hygrothermal aging effects on polymer tensile strength and elongation-at-break (e.g., PET film dimensional stability at 85°C/85% RH).
• Peel adhesion testing of pressure-sensitive tapes under low-temperature conditions (−40°C) to simulate automotive winter performance.
• Compression modulus mapping of hydrogels across physiological humidity gradients (37°C, 95% RH).
• Shear strength validation of structural adhesives used in aerospace composite bonding per Boeing BSS 7260.
• Dynamic mechanical analysis (DMA)-correlative tensile testing for viscoelastic transition identification in thermoplastic elastomers.
• Quality control of medical device packaging integrity (ASTM F88 seal strength) under accelerated aging protocols (ICH Q1A).

FAQ

Can the environmental chamber be customized for non-standard internal dimensions?
Yes—Yuelian offers OEM chamber modifications including extended depth (up to 120 cm), reinforced viewing windows, and inert gas purge ports (N₂ or Ar) upon request.
Is third-party calibration certification included with delivery?
Factory calibration is performed per ISO/IEC 17025-accredited procedures; NIST-traceable calibration certificates (force, temperature, humidity) are available as optional add-ons.
Does the system support automated fixture alignment verification?
The software includes a pre-test alignment routine that verifies parallelism between upper/lower grips using integrated displacement sensors and prompts corrective action if deviation exceeds ±0.02 mm.
What is the maximum allowable specimen thickness when the chamber is installed?
With chamber mounted, maximum specimen thickness is constrained by the 40 cm chamber height and standard grip geometry; typical limit is 150 mm—custom low-profile grips can extend this to 250 mm.
How is humidity uniformity validated inside the chamber during operation?
Uniformity is verified per ISO 16710 Annex B using three calibrated hygrometers placed at geometric center and opposing corners; all units demonstrate ≤±1.5% RH spatial deviation at steady state.
