Overview
The Drick DRKWL-500 is a horizontally configured electromechanical tensile testing machine engineered for precision mechanical property evaluation of low-force, flexible sheet and film materials. It operates on the principle of controlled uniaxial tension—applying calibrated axial force via a stepper motor-driven ball screw actuator while simultaneously measuring load (via high-accuracy load cell) and displacement (via optical encoder-based linear measurement). Designed to meet rigorous international metrological standards—including ISO 7500-1 (static calibration of force-proving instruments), ASTM E4 (verification of force-measuring systems), and ISO 527-2 (tensile testing of plastics)—the DRKWL-500 delivers traceable, repeatable results in compliance with GLP and GMP-aligned laboratory practices. Its horizontal architecture minimizes gravitational influence on specimen alignment and eliminates sag-related error—critical for thin films, coated papers, and laminated structures where self-weight may distort deformation behavior.
Key Features
- High-stiffness dual-linear-rail guidance system paired with preloaded ball screw transmission ensures minimal lateral deviation (<0.02 mm/m) and exceptional motion repeatability across full stroke.
- Stepper motor drive enables smooth, silent operation with programmable speed profiles (1–500 mm/min, infinitely variable), supporting both constant-rate and multi-segment test protocols.
- 24-bit high-resolution analog-to-digital converter (ADC) provides effective resolution up to 1 part in 10,000,000, enabling detection of sub-millinewton force changes during initial loading or creep phases.
- 7-inch capacitive touchscreen interface with bilingual (English/Chinese) GUI supports real-time visualization of force–time, force–displacement, and force–strain curves; local data storage (≥10,000 test records) and USB export capability included.
- Integrated thermal line printer outputs calibrated test reports directly—displaying mean values, standard deviation, coefficient of variation, and pass/fail status against user-defined limits.
- Automatic safety functions include overload cutoff (at 110% F.S.), emergency stop, end-of-travel limit sensing, and auto-return-to-initial-position post-test.
Sample Compatibility & Compliance
The DRKWL-500 is optimized for specimens with nominal widths of 15 mm (standard pneumatic or manual wedge grips supplied); optional grip sets accommodate widths from 5 mm to 50 mm and thicknesses up to 3 mm. It supports standardized tests per ASTM D882 (thin plastic sheeting), ASTM D638 (plastics tensile properties), ISO 527-2 (Type 1B specimens), GB/T 1040.3 (plastics—film and sheet), GB/T 4850 (peel adhesion), GB/T 2790 (adhesive peel strength), and QB/T 2358 (heat seal strength). All mechanical and electrical subsystems conform to IEC 61000-4 electromagnetic compatibility requirements, and force calibration traceability is maintained to national metrology institutes via annual verification per ISO/IEC 17025-accredited service providers.
Software & Data Management
Firmware v3.2 includes built-in statistical analysis modules compliant with ISO 5725 (accuracy and precision of measurement methods) and supports configurable report templates aligned with internal QA documentation workflows. Raw data export (CSV, TXT) preserves timestamped force/displacement arrays at ≥100 Hz sampling rate. Optional PC-based software (DRK-TestSuite Pro) adds advanced curve fitting (e.g., Young’s modulus calculation via ISO 527-1 secant method), batch reporting, audit trail logging per FDA 21 CFR Part 11 requirements (with electronic signature support), and networked instrument fleet management.
Applications
Primary applications include tensile strength, elongation at break, elastic modulus, yield point, and energy-to-break determination for paperboard, BOPP/CPP/PE films, aluminum foil laminates, medical packaging pouches, label stocks, and textile nonwovens. Secondary test modes enabled by interchangeable fixtures include 180° peel adhesion (ASTM D903), heat seal strength (ASTM F88), tear resistance (ASTM D1938), and puncture resistance (ASTM F1306). The 500 mm stroke allows full extension testing of high-elongation elastomeric films without specimen repositioning.
FAQ
What is the maximum specimen length supported for uninterrupted testing?
The effective test zone accommodates specimens up to 500 mm long; however, usable gauge length depends on fixture spacing and must be defined per ASTM D882 (minimum 50 mm) or ISO 527-2 (minimum 50 mm for Type 1B).
Can the DRKWL-500 be integrated into an LIMS environment?
Yes—via optional RS-232 or Ethernet interface, the instrument supports ASTM E1382-compliant data streaming and SCADA-compatible OPC UA drivers for seamless LIMS connectivity.
Is third-party calibration certification available?
Drick provides ISO/IEC 17025-accredited calibration certificates (traceable to NIM, China) upon request; annual recalibration is recommended per ISO/IEC 17025 Clause 6.5.2.
Does the system comply with FDA 21 CFR Part 11 for electronic records?
The base firmware does not include Part 11 functionality; however, the optional DRK-TestSuite Pro software implements role-based access control, electronic signatures, and immutable audit trails required for regulated pharmaceutical and medical device labs.
