Yuelian PW-YT1-80 Environmental Universal Testing Machine with Integrated Temperature Chamber

Overview

The Yuelian PW-YT1-80 Environmental Universal Testing Machine integrates a high-performance electromechanical universal testing system with a fully independent, vertically configurable temperature chamber—enabling precise mechanical property evaluation of materials under controlled thermal conditions. Engineered for ISO 527, ASTM D638, ASTM D882, ASTM D903, ISO 8510-2, and GB/T 2792 tensile, peel, shear, tear, compression, and flexural testing protocols, this dual-module platform supports both ambient and extreme-temperature mechanical characterization across polymers, adhesives, films, composites, elastomers, and biomedical packaging. Unlike conventional ambient-only testers, the PW-YT1-80 employs a thermally isolated chamber design: the environmental chamber can be physically detached from the load frame for rapid reconfiguration to standard room-temperature operation—maximizing lab flexibility without hardware duplication. Its force measurement architecture complies with ISO 7500-1 Class 0.5 accuracy requirements, while the integrated PID-controlled thermal subsystem maintains uniformity within ±1 °C across the full 40 L test volume per IEC 60068-3-5.

Key Features

• Modular architecture: Removable temperature chamber (400 × 400 × 800 mm internal volume) enables seamless transition between environmental and ambient-mode testing
• High-fidelity force measurement: 250,000-count resolution load cell with ≤ ±0.5% full-scale accuracy, traceable to national metrology standards
• Precision motion control: Servo-driven crosshead with ball-screw transmission delivers repeatable displacement resolution of 0.005 mm and programmable speed range from 0.5 to 500 mm/min
• Thermal performance: Dual-zone climate control system featuring SUS304 finned heating elements, high-COP compressor cooling (R404A), and forced-air circulation ensures ±1 °C uniformity at any setpoint from −70 °C to +150 °C
• Comprehensive safety suite: Redundant protection layers including thermal runaway cutoff, compressor overload relay, emergency stop circuit, specimen failure-triggered halt, and software-enforced travel limits
• Structural integrity: Rigid M12 bolted base frame with reinforced upright columns; total mass of 420 kg minimizes vibration-induced noise during dynamic loading

Sample Compatibility & Compliance

The PW-YT1-80 accommodates specimens conforming to standard geometries defined in ISO 527-2 (dog-bone tensile bars), ASTM D882 (thin films), ISO 8510-2 (peel test strips), and ASTM D1876 (T-peel configurations). Its Ø140 mm test width and 650 mm stroke support multi-layer laminates, pressure-sensitive adhesives (PSAs), battery separator membranes, and thermoformed medical pouches. All thermal and mechanical subsystems comply with CE machinery directive 2006/42/EC, electromagnetic compatibility (EMC) directive 2014/30/EU, and RoHS 2011/65/EU. The controller firmware implements audit-trail logging per FDA 21 CFR Part 11 requirements when paired with validated Windows OS configurations and digital signature-enabled software deployment.

Software & Data Management

The embedded PC-based control software (Windows 10/11 compatible) provides real-time acquisition of force, displacement, temperature, and time data at up to 1 kHz sampling rate. It supports automated calculation of tensile strength, elongation at break, Young’s modulus, peel adhesion energy (J/m²), 180° peel average force (N/mm), and yield point identification using ASTM E111 tangent offset methods. Raw data is stored in encrypted MS-ACCESS databases with timestamped metadata—including operator ID, calibration certificate ID, environmental chamber log, and test parameter version history. Graphical post-processing includes stress–strain overlay, comparative curve alignment, statistical batch reporting (mean ± SD, CV%), and export to CSV, PDF, or XML for LIMS integration. Optional validation packages include IQ/OQ documentation templates aligned with GLP and GMP Annex 11 expectations.

Applications

• Temperature-dependent tensile analysis of polyolefin films used in pharmaceutical blister packaging (−20 °C to 40 °C)
• Low-temperature peel adhesion assessment of medical device PSA tapes per ISO 25537
• High-temperature creep resistance evaluation of automotive under-hood elastomers (120 °C sustained load)
• Thermal cycling fatigue testing of flexible printed circuit board (FPCB) laminates
• Validation of battery electrode binder cohesion across charge/discharge thermal profiles
• Quality control of food-grade laminated pouch seal integrity at sterilization temperatures (121 °C)

FAQ

Can the temperature chamber be operated independently of the mechanical tester?
Yes—the chamber is mechanically and electrically decoupled and may be powered and controlled separately for standalone thermal aging or conditioning applications.
Is the system compliant with ASTM D1002 for adhesive lap-shear testing?
Yes, when equipped with appropriate rigid grip fixtures and calibrated per ASTM E4, the system meets all dimensional, alignment, and rate-control requirements specified in D1002.
What calibration documentation is supplied with delivery?
Each unit ships with factory calibration certificates for load cell (traceable to CNAS-accredited lab), displacement encoder, and temperature sensors—all valid for 12 months from shipment date.
Does the software support multi-user role-based access control?
Yes—administrator, operator, and reviewer roles are enforced with password-protected login, session timeout, and electronic signature capture for critical actions such as method modification or report approval.
Are custom grips or environmental chamber modifications available?
Yes—Yuelian offers OEM engineering services for application-specific fixtures (e.g., pneumatic side-action clamps, cryogenic submersible grips) and chamber extensions (e.g., extended height for vertical cable testing).
