Drick DRK505 Ball Impact Tester for Plastic Sheets ≤2 mm Thickness

Overview

The Drick DRK505 Ball Impact Tester is a precision-engineered mechanical impact testing system designed specifically for evaluating the impact resistance of thin plastic sheets with nominal thicknesses up to 2 mm. It operates on the principle of free-fall impact testing in accordance with standardized drop-ball methodologies—where a calibrated steel sphere is electromagnetically released from a defined vertical height onto the center of a horizontally clamped specimen. The resulting damage (e.g., cracking, puncture, or complete penetration) is visually assessed and statistically quantified across multiple replicates to determine failure probability or pass/fail compliance against pharmaceutical packaging, medical device, and industrial film specifications. Unlike generalized impact testers, the DRK505 integrates height repeatability, pneumatic clamping stability, and electromagnetic release timing to minimize operator-induced variability—ensuring high reproducibility required for QC/QA environments under GLP-aligned workflows.

Key Features

• Pneumatic specimen clamping system ensures consistent, uniform pressure distribution across the test area—eliminating edge slippage and localized stress concentration during impact.
• Electromagnetic ball suspension and release mechanism guarantees precise temporal control (<±5 ms timing resolution), removing manual release inconsistencies inherent in mechanical triggers.
• Adjustable drop height range from 300 mm to 600 mm (with extended option up to 2000 mm) enables method flexibility across diverse material stiffness profiles and regulatory requirements.
• Interchangeable steel ball set (23 mm, 25 mm, 28.6 mm, 38.1 mm, 50.8 mm diameters) supports multi-standard testing—including ISO 7765-1, ASTM D1709 (for film), and Chinese YBB pharmacopoeial standards.
• Integrated optical centering guide and laser-assisted alignment aid ensure repeatable impact positioning within ±0.5 mm tolerance relative to specimen centroid—critical for statistical validity in low-thickness substrates.
• Foot-operated start switch allows hands-free initiation, improving operator ergonomics and reducing procedural interruption during high-throughput laboratory sessions.

Sample Compatibility & Compliance

The DRK505 is validated for rigid and semi-rigid thermoplastic sheets including PET, PVC, PP, PS, and laminated co-extrusions used in blister packaging, diagnostic device housings, and sterile barrier systems. Its design conforms to the geometric and procedural constraints specified in YBB00212005–2015 (plastic infusion bottles), YBB00222005–2015 (plastic ampoules), YBB00232005–2015 (plastic syringes), and YBB00242002–2015 (plastic caps). While not certified to ISO/IEC 17025, the instrument’s mechanical traceability, height calibration protocol (using NIST-traceable digital calipers), and documented maintenance log support audit readiness for FDA 21 CFR Part 11–aligned quality systems when paired with controlled electronic data capture.

Software & Data Management

The DRK505 operates as a standalone hardware platform without embedded firmware or proprietary software. All test parameters—including drop height, ball diameter, specimen ID, and pass/fail outcome—are manually recorded per test sequence using laboratory notebooks or LIMS-integrated spreadsheets. For laboratories requiring electronic records, the system is compatible with third-party data acquisition modules (e.g., National Instruments DAQ systems) via TTL-triggered I/O ports for synchronized event logging. Audit trails, user access logs, and electronic signature functionality must be implemented externally through validated LIMS or ELN platforms compliant with 21 CFR Part 11 Annex 11 requirements.

Applications

• Pharmaceutical packaging validation: Determining puncture resistance of blister lidding foils and cold-forming aluminum-plastic composites.
• Medical device component qualification: Assessing impact survivability of thin polymer housings for disposable diagnostics and wearable sensors.
• Automotive interior film screening: Evaluating scratch-and-impact synergy in decorative overlays under simulated mechanical abuse conditions.
• Recycled polymer film certification: Supporting ASTM D790/D747 comparative analysis for mechanical integrity retention after reprocessing cycles.
• Regulatory submission support: Generating raw data packages for ANDA, DMF, and CE Technical Documentation dossiers where YBB or equivalent national standards apply.

FAQ

What standards does the DRK505 explicitly support?
The DRK505 is configured and validated for YBB00212005–2015, YBB00222005–2015, YBB00232005–2015, and YBB00242002–2015. It also accommodates test protocols aligned with ISO 7765-1 and ASTM D1709 when appropriate ball masses and heights are selected.
Can the DRK505 test specimens thicker than 2 mm?
No—the mechanical fixture geometry, clamping force profile, and energy transfer dynamics are optimized exclusively for specimens ≤2 mm. Testing thicker materials may compromise alignment accuracy and invalidate compliance claims.
Is calibration documentation included with shipment?
Yes—a factory calibration certificate verifying drop height linearity (±0.5 mm tolerance over full range) and pneumatic clamp pressure consistency (±2 psi) is supplied with each unit. Users are advised to perform periodic verification using traceable gauge blocks and pressure calibrators.
Does the system meet electromagnetic compatibility (EMC) requirements for EU deployment?
The DRK505 complies with IEC 61326-1:2013 Class A emission limits and basic immunity per EN 61326-2-1. CE marking is provided upon request with applicable technical construction file (TCF) documentation.
Are replacement steel balls and pneumatic components available as spare parts?
Yes—Drick maintains an inventory of certified AISI 52100 hardened steel balls (HRC 60–65), pneumatic cylinder seals, solenoid valves, and foot-switch assemblies. Lead time for custom-diameter balls is typically 4–6 weeks.
