Overview
The Labthink CYZ-6S Constant Load Adhesion Tester is an engineered solution for quantifying the holding power (creep resistance) of pressure-sensitive adhesive materials under sustained vertical loading. It operates on the principle of static shear adhesion: a standardized test specimen—comprising adhesive-coated substrate bonded to a stainless steel or aluminum test plate—is mounted vertically and subjected to a precisely defined dead load. The instrument measures either the time required for complete detachment or the displacement (slippage) of the specimen after a predetermined duration. This methodology directly reflects real-world performance scenarios where adhesive tapes, transdermal patches, protective films, and labeling materials are exposed to constant gravitational stress over extended periods. Designed in strict accordance with internationally recognized test protocols—including GB/T 4851 (China), ASTM D3654 (USA), and JIS Z0237 (Japan)—the CYZ-6S delivers repeatable, traceable, and auditable results suitable for QC release testing, R&D formulation validation, and regulatory submission support.
Key Features
- Six independent test stations enable parallel evaluation of multiple specimens, significantly improving throughput and statistical robustness without cross-contamination or mechanical interference.
- Microprocessor-controlled timing system with automatic start/stop logic and digital lock-in functionality ensures precise exposure duration, eliminating operator-dependent variability.
- Integrated LCD display and tactile PVC membrane keypad provide intuitive local operation and real-time status monitoring—no external PC required for basic test execution.
- Calibrated stainless steel test plates (60 mm × 40 mm × 1.5 mm) and certified loading masses (1000 g ± 10 g, inclusive of loading plate) meet dimensional and mass tolerances specified in ASTM D3654 and GB/T 4851.
- Standardized 2000 g ± 50 g rubber roller ensures uniform contact pressure during specimen preparation, critical for reproducible bond formation prior to vertical loading.
- Universal dual-voltage power supply (220 VAC 50 Hz / 120 VAC 60 Hz) supports deployment across global laboratory environments without hardware modification.
Sample Compatibility & Compliance
The CYZ-6S accommodates a broad spectrum of pressure-sensitive adhesive products, including but not limited to BOPP packaging tapes, aluminum foil tapes, medical transdermal patches, silicone-based surgical tapes, acrylic and rubber-based labels, and PET/PE protective films. All test configurations comply with the geometric, material, and procedural requirements outlined in GB/T 4851–2022 (revised edition), ASTM D3654–18, and JIS Z0237:2021. For pharmaceutical applications, the instrument supports documentation workflows aligned with GLP and GMP principles; raw timing data and detachment events are timestamped and stored locally, enabling retrospective audit trails when integrated into validated laboratory information management systems (LIMS).
Software & Data Management
While the CYZ-6S functions autonomously via its embedded controller, optional RS-232 or USB serial interface allows direct data export to external PCs for automated reporting and long-term archival. Exported records include test station ID, start/stop timestamps, observed slippage distance (if measured manually post-test), and pass/fail flags based on user-defined acceptance criteria. When deployed in regulated environments, the device supports integration with electronic lab notebooks (ELN) and complies with metadata retention expectations under FDA 21 CFR Part 11 when paired with appropriate access controls and electronic signature protocols.
Applications
- Quality control of industrial packaging tapes for logistics durability assessment.
- Formulation screening of hot-melt and solvent-based PSAs for extended service life prediction.
- Stability testing of medical adhesives under accelerated aging conditions (e.g., 40 °C/75% RH).
- Comparative evaluation of backing substrate influence (e.g., cloth vs. film) on creep resistance.
- Supporting USP and Ph. Eur. 2.9.38 compliance for topical patch adhesion validation.
- Root cause analysis of field failures related to adhesive cold flow or interfacial delamination.
FAQ
What standards does the CYZ-6S directly support?
GB/T 4851, ASTM D3654, and JIS Z0237—each implemented with hardware-level adherence to specimen geometry, load mass tolerance, and environmental conditioning requirements.
Can test results be exported for regulatory submission?
Yes—via serial interface to CSV or TXT formats; full audit trail capability requires integration with compliant LIMS or ELN platforms.
Is calibration certification included with shipment?
A factory-issued calibration report verifying load mass and timer accuracy is provided; third-party ISO/IEC 17025 calibration is available upon request.
How is specimen alignment ensured across all six stations?
Each station features machined locating pins and recessed plate seating to guarantee consistent vertical orientation and load vector alignment per standard specifications.
Does the instrument require periodic maintenance?
No consumables or lubrication are required; routine verification of load mass integrity and timer drift every 6 months is recommended for ISO-compliant operation.
