Overview
The Drick WDW Series Electronic Universal Testing Machine is a precision-engineered electromechanical system designed for static mechanical property evaluation of metallic and non-metallic materials under controlled uniaxial loading conditions. Based on servo-controlled ball-screw actuation and high-fidelity load cell transduction, the system implements standardized force-displacement measurement principles aligned with ISO 6892-1 (tensile testing of metals), ASTM D638 (plastics), ASTM D412 (rubber), ASTM D882 (thin plastic films), and IEC 60811 (electric cables). Unlike hydraulic systems, the WDW series employs brushless AC servo motors and precision ground ball screws to deliver repeatable, low-noise motion control — essential for high-resolution modulus determination, yield point identification, and elongation-at-break quantification in wire-and-cable insulation, conductor stranding, jacketing polymers, and composite reinforcement fibers.
Key Features
- Modular electromechanical architecture with dual-column rigid frame construction, engineered for torsional stability and minimal deflection during high-load compression or tensile tests.
- High-accuracy load measurement using S-type or cantilever beam load cells calibrated to ISO 376 Class 0.5 or better; factory-certified traceability to national metrology institutes.
- Real-time closed-loop speed and position control via digital servo driver, supporting programmable multi-step test profiles (e.g., pre-load → ramp → hold → return) compliant with ISO 527-1 and ASTM D790.
- Integrated safety interlocks including hardware-based upper/lower limit switches, emergency stop circuitry, and software-enforced overload cutoff (configurable threshold).
- Front-accessible crosshead adjustment with quick-release mechanism for rapid specimen alignment and gauge length setup — optimized for routine QC testing of insulated conductors and sheathed cables per UL 1581 or EN 50363.
- Robust structural design meeting CE Machinery Directive 2006/42/EC requirements; vibration-damped base plate minimizes environmental interference during low-force measurements (≤0.1 kN).
Sample Compatibility & Compliance
The WDW platform accommodates standardized specimens defined in IEC 60227, IEC 60245, GB/T 2951, and ASTM B33 for copper/aluminum conductors, PVC/NBR/EPR insulation layers, LSZH jackets, and braided shielding tapes. Fixture options include pneumatic wedge grips (for wires ≥0.5 mm diameter), roller-type clamps (for flat ribbons), and custom-designed cable-end anchoring fixtures that prevent slippage during high-strain elongation. All mechanical test protocols support audit-ready documentation per GLP and ISO/IEC 17025 requirements, with optional calibration certificate packages including uncertainty budgets per ISO/IEC 17025:2017 Annex A.3.
Software & Data Management
The system operates under Windows OS (Windows 10 64-bit compatible) with proprietary VB.NET-based test control software featuring dual-mode operation: guided wizard mode for routine cable tensile qualification (e.g., “IEC 60227-2 Pull Test”) and advanced script mode for user-defined test sequences. Software modules include real-time curve overlay (load vs. displacement, stress vs. strain), automatic yield strength calculation (0.2% offset method), modulus extraction (secant/tangent), and statistical batch reporting (mean, SD, CV%, min/max). Raw data export supports CSV, XML, and PDF formats; optional 21 CFR Part 11 compliance package provides electronic signature capability, audit trail logging, and role-based access control.
Applications
- Tensile strength and elongation testing of stranded copper conductors (annealed/hard-drawn) per IEC 60228.
- Insulation adhesion strength assessment between conductor and PVC/XLPE layers using peel or shear fixtures.
- Compression resilience evaluation of cable bedding compounds and filler gels under sustained load.
- Bending fatigue simulation via cyclic flexing fixtures (optional add-on) for evaluating jacket integrity after 10,000+ cycles.
- Quality conformance verification for UL-listed cable assemblies, including jacket thickness correlation with tensile performance.
- R&D validation of halogen-free flame-retardant (HFFR) compounds under combined thermal-mechanical stress protocols.
FAQ
What standards does the WDW series comply with for wire-and-cable testing?
It supports full implementation of IEC 60227, IEC 60245, EN 50363, UL 1581, GB/T 2951, and ASTM D1238 (melt flow index correlation via tensile creep modules).
Can the system perform creep or stress-relaxation tests?
Yes — with optional time-dependent test modules and extended dwell control, enabling ISO 899-1 creep compliance up to 10,000 hours at constant load.
Is third-party calibration certification available?
Yes — NIST-traceable calibration certificates with expanded uncertainty statements are provided upon request, conforming to ISO/IEC 17025 requirements.
What is the minimum resolvable force for the 0.01 kN configuration?
The system achieves ≤0.0005 kN resolution (0.5 N) with 24-bit ADC sampling and digital noise filtering algorithms.
Does the software support automated report generation for ISO/IEC 17025 accredited labs?
Yes — templates include mandatory metadata fields (operator ID, equipment ID, environmental conditions, calibration dates) and auto-populated pass/fail flags against specification limits.
