Generic Desktop Tensile Testing Machine – Model DT-500 Series

Overview

The Generic Desktop Tensile Testing Machine – Model DT-500 Series is an electromechanical universal testing system engineered for precision uniaxial tensile, peel, shear, and elongation measurements in R&D laboratories and quality control environments. It operates on the fundamental principle of controlled displacement-driven force measurement, utilizing a high-fidelity servo-controlled actuation system to apply defined strain rates while continuously acquiring load and extension data. Designed for benchtop deployment, the system delivers laboratory-grade repeatability without requiring floor-mounted infrastructure or dedicated environmental enclosures. Its architecture adheres to ISO 7500-1 Class 1 calibration requirements for force measurement systems and supports traceable verification per GB/T 16491 — China’s national standard equivalent to ISO 7500-1 and ASTM E4. The machine is routinely deployed in polymer science labs, packaging validation units, textile QA facilities, and medical device component testing centers where standardized mechanical property characterization under ambient conditions is required.

Key Features

• Panasonic AC servo motor with closed-loop feedback control ensures consistent speed accuracy across the full range (0.001–500 mm/min), minimizing velocity drift during extended creep or stress-relaxation protocols.
• High-precision preloaded ball screw transmission combined with linear motion guide rails enables smooth, low-noise axial movement with minimal backlash (< 2 µm) and long-term positional stability.
• Explosion-proof S-type load cell with automatic thermal compensation delivers ±0.03% full-scale accuracy, <0.01% zero drift over 8 hours, and transient overload tolerance up to 150% FS without recalibration.
• Dual-stage hardware and software travel limit protection prevents mechanical overtravel and safeguards the load cell from impact damage during specimen rupture or operator error.
• Real-time data acquisition at 1 kHz sampling rate with 24-bit ADC resolution provides high-fidelity stress–strain curve reconstruction, including precise yield point, modulus, elongation at break, and peak load detection.
• Integrated upper-limit load alarm function triggers immediate motor stop and visual alert when preset force thresholds are exceeded—critical for preserving sensor integrity during high-strength composite or metal foil testing.

Sample Compatibility & Compliance

The DT-500 accommodates specimens ranging from ultra-thin films (≥10 µm thickness) to rigid polymer rods (up to Ø12 mm), textiles (woven/nonwoven), elastomeric strips, adhesive tapes, biomedical sutures, and laminated packaging structures. Standardized grips include pneumatic film clamps, wedge-action tensile jaws, 90°/180° peel fixtures, and shear test platens—all compliant with dimensional tolerances specified in GB/T 2790, GB/T 2792, and GB/T 3923.1. All test methods implemented via software align with mandatory Chinese national standards (GB/T series), and the system’s measurement uncertainty budget satisfies GLP documentation requirements for internal QC reporting. While not certified to ISO/IEC 17025, the platform supports audit-ready calibration records and traceable certificate generation for metrological compliance in regulated manufacturing settings.

Software & Data Management

The proprietary Windows-based control and analysis software provides ISO/IEC 17025-aligned test method configuration, real-time curve overlay, multi-curve statistical comparison (mean ± SD), and automated report generation in PDF/Excel formats. Each test file embeds metadata including operator ID, timestamp, environmental temperature/humidity (if external sensors are connected), calibration status, and instrument serial number. Audit trail functionality logs all parameter modifications, test start/stop events, and data export actions—meeting FDA 21 CFR Part 11 requirements for electronic records when deployed with user authentication and electronic signature modules. Raw data export supports CSV and ASCII formats for third-party statistical analysis (e.g., JMP, Minitab) or integration into LIMS platforms via ODBC drivers.

Applications

• Mechanical characterization of thermoplastics and thermosets per GB/T 1040 (tensile properties) and GB/T 528 (vulcanized rubber).
• Peel strength evaluation of pressure-sensitive adhesives using 90° and 180° configurations per GB/T 2790 and GB/T 2792.
• Seal strength testing of flexible packaging materials (e.g., pouches, laminates) in accordance with GB/T 8808.
• Elongation and breaking strength assessment of nonwovens, woven fabrics, and geotextiles per GB/T 3923.1.
• Shear resistance quantification of structural adhesives and composite interlayers per GB/T 7124 and GB/T 20310.
• Quality conformance testing for automotive interior trim, medical tubing, and consumer electronics encapsulants under GB/T 16825 and GB/T 2611.

FAQ

Does this system support ASTM or ISO test methods?

Yes — while calibrated and validated against GB/T standards, the machine’s force and displacement metrology meet the performance criteria of ASTM E4 and ISO 7500-1. Users may configure custom test protocols aligned with ASTM D638, D882, D903, or ISO 527, provided specimen geometry and fixture compatibility are verified.

Is the load cell factory-calibrated and NIST-traceable?

Each unit ships with a manufacturer-issued calibration certificate referencing a national metrology institute (NIM, China). Optional NIST-traceable recalibration services are available through authorized service partners upon request.

Can the software generate GLP-compliant test reports?

Yes — when configured with role-based access control and electronic signature modules, the software generates fully auditable reports containing instrument ID, calibration due date, operator credentials, raw data checksums, and revision history — satisfying basic GLP documentation requirements.

What is the maximum specimen length supported?

The effective test stroke is 800 mm; with standard grips, maximum specimen gauge length is 500 mm. Extended travel options (up to 1,200 mm) are available as configurable accessories.

Is technical support available outside mainland China?

Yes — global distributor networks provide installation supervision, operator training, preventive maintenance scheduling, and remote diagnostics via secure TeamViewer sessions with English-speaking application engineers.
