Overview
The Labthink C670M Dart Impact Tester is a precision-engineered instrument designed to quantify the impact resistance of flexible packaging films and thin plastic sheets under controlled free-fall conditions. It operates on the principle of standardized dart drop impact testing—where a weighted dart is released from a defined height onto a horizontally clamped specimen, and the energy required to cause failure (penetration or rupture) is determined either via the ASTM D1709 “up-and-down” method or the GB 9639 single-height threshold method. This test directly correlates with real-world performance during filling, handling, stacking, and distribution—where sudden mechanical shocks may compromise package integrity and lead to product leakage, contamination, or spoilage. The C670M delivers high reproducibility in impact energy measurement across a broad range of film structures—including mono-layer PE, BOPP, PET, CPP, aluminum-laminates, and metallized substrates—making it indispensable for QC laboratories in packaging manufacturing, food & pharma packaging R&D, and contract testing facilities.
Key Features
- Compliant dual-mode operation: Supports both Method A (single-height, pass/fail threshold) per GB 9639 and Method B (variable-height, statistical median impact energy) per ASTM D1709 and JIS K7124.
- Motorized height adjustment with digital encoder feedback ensures ±1 mm positional accuracy over the 0–1500 mm vertical travel range.
- Interchangeable darts (50 g, 100 g, 200 g, 500 g) with precision-machined hemispherical tips (R = 1.6 mm per ASTM D1709), calibrated traceable to NIST-equivalent national standards.
- Robust clamping system with pneumatic actuation and adjustable clamping force (0–200 N) ensures consistent specimen tension without edge deformation or slippage.
- Integrated optical sensor array detects dart impact and specimen failure in <10 ms, eliminating operator subjectivity and enabling unattended batch testing.
- Self-diagnostic firmware with real-time error logging and calibration status monitoring supports ISO/IEC 17025-compliant laboratory workflows.
Sample Compatibility & Compliance
The C670M accommodates specimens up to 150 mm × 150 mm with thicknesses ranging from 20 µm to 500 µm. It is validated for use with polyolefin-based films (LDPE, HDPE, PP), polyester (PET), polyamide (PA), cellulose derivatives, and multilayer laminates including foil- and barrier-coated structures. All test procedures align with internationally recognized standards: GB 9639–2008 (China), ASTM D1709–22 (USA), JIS K7124:2017 (Japan), and ISO 7765-1:2022 (Plastics — Film and sheeting — Determination of impact resistance — Part 1: Free falling dart method). Instrument design and documentation support GLP/GMP environments, including audit-ready calibration records, user access control logs, and electronic signature capability compliant with FDA 21 CFR Part 11 when integrated with Labthink’s proprietary TS21 software platform.
Software & Data Management
The C670M interfaces seamlessly with Labthink’s TS21 TestSuite™ v3.2—a validated Windows-based application supporting automated test sequencing, real-time force/displacement curve visualization, statistical analysis (mean, SD, CV%, confidence intervals), and customizable report generation (PDF, Excel, XML). Raw data files are stored with embedded metadata (operator ID, timestamp, environmental conditions, calibration certificate ID), ensuring full traceability. Audit trail functionality records all user actions—including method edits, result overrides, and calibration events—with immutable timestamps. Data export complies with LIMS integration protocols (ASTM E1469, HL7) and supports CSV/ODS formats for third-party statistical packages such as JMP or Minitab.
Applications
- Quality assurance of shrink sleeves and stand-up pouches subjected to high-speed vertical form-fill-seal (VFFS) operations.
- Evaluation of seal integrity in peelable lidding films used in medical device packaging under simulated transit shock.
- Comparative assessment of impact resistance between virgin and recycled polymer blends in sustainable packaging development.
- Stability screening of barrier films exposed to accelerated aging (40°C/75% RH) to detect embrittlement-induced impact sensitivity shifts.
- Regulatory submission support for FDA 510(k) or EU MDR packaging validation dossiers requiring mechanical robustness evidence.
FAQ
What standards does the C670M comply with?
The instrument meets GB 9639–2008, ASTM D1709–22, JIS K7124:2017, and ISO 7765-1:2022 for free-falling dart impact testing.
Can the C670M be used for non-plastic materials such as paperboard or aluminum foil?
It is optimized for flexible films and thin sheets (≤500 µm); rigid substrates exceeding 300 µm thickness or exhibiting low ductility may yield non-representative results and are not recommended.
Is calibration certification included with shipment?
Yes—each unit ships with a factory calibration certificate traceable to CNAS-accredited reference standards, valid for 12 months under normal operating conditions.
Does the system support IQ/OQ/PQ documentation for regulated industries?
Full qualification documentation packages—including Installation Qualification (IQ), Operational Qualification (OQ), and Performance Qualification (PQ) protocols—are available upon request and aligned with ISO 13485 and ICH Q5E requirements.
How often does the dart tip require replacement?
Dart tips must be inspected before each test series; replacement is mandatory after 500 impacts or if visible wear, chipping, or radius deviation (>±0.1 mm) is observed.
