Overview
The Labthink CZY-6S Constant-Temperature Pressure-Sensitive Adhesive Tape Holding Power Tester is an engineered solution for quantifying the resistance of pressure-sensitive adhesives (PSAs) to shear stress under static load conditions. Based on the fundamental principle of vertical hanging shear testing—where a standardized test specimen is affixed to a polished stainless-steel plate, vertically suspended, and subjected to a defined deadweight—the instrument measures either the displacement of the specimen over time or the elapsed time until complete detachment. This methodology directly reflects real-world performance of PSAs used in medical transdermal patches, protective films, labeling systems, and industrial masking tapes, where long-term bond integrity under gravitational or low-shear forces is critical. The device operates at ambient laboratory temperature (23 ±2 °C, per ISO 291 conditioning requirements), ensuring repeatability across routine QC environments without thermal regulation complexity.
Key Features
- Six independent test stations enable parallel evaluation of multiple specimens—significantly improving throughput for batch release testing and comparative formulation studies.
- Microprocessor-based control system with PVC membrane keypad and LCD display provides intuitive operation, real-time status feedback, and precise timing resolution down to 1 second.
- All mechanical components—including test plates, loading plates, and standard weights—are manufactured to exact dimensional and mass tolerances specified in GB/T 4851, ASTM D3654, and JIS Z0237, eliminating inter-laboratory variability due to hardware deviation.
- Automatic timing initiation upon weight application and auto-lock functionality prevent operator-induced timing errors and ensure data traceability.
- Robust steel frame construction with vibration-dampening base ensures mechanical stability during extended tests (up to 10,000 hours), minimizing false detachments caused by environmental micro-vibrations.
Sample Compatibility & Compliance
The CZY-6S accommodates a broad range of pressure-sensitive materials, including acrylic, rubber-based, and silicone adhesives applied to backing substrates such as PET, PE, paper, nonwovens, and aluminum foil. It supports testing of medical-grade adhesive patches (e.g., ECG electrodes, drug delivery systems), surface protection films for electronics and automotive components, self-adhesive labels per ISO 10999, and industrial transfer tapes. All test procedures align with internationally recognized standards: GB/T 4851 (China), ASTM D3654-22 (Standard Test Method for Holding Power of Pressure-Sensitive Tapes), and JIS Z0237:2021 (Adhesive Tapes — Test Methods). The instrument’s design facilitates full audit readiness for GLP and GMP-regulated environments, supporting documented calibration records and user-accessible maintenance logs.
Software & Data Management
While the base CZY-6S operates via embedded firmware without PC connectivity, optional RS-232 or USB interface modules allow integration with Labthink’s proprietary data acquisition software (v3.2+). This software enables automated timestamped logging of detachment events per station, export of raw timing data in CSV format, and generation of compliant test reports aligned with FDA 21 CFR Part 11 requirements—including electronic signatures, audit trails, and user permission levels. All measurement data are stored with metadata: operator ID, sample ID, test date/time, environmental temperature/humidity (when linked to external sensors), and calibration certificate references.
Applications
- Quality control of PSA-coated products prior to packaging and distribution.
- Formulation development support—comparing holding power across adhesive chemistries, crosslinking densities, or coating weights.
- Stability assessment of aged or accelerated-weathered tape samples per ISO 11341.
- Regulatory submission testing for Class I/II medical devices requiring ISO 10993-5 cytotoxicity-coupled adhesion validation.
- Supplier qualification protocols where contractual holding power thresholds (e.g., ≥10,000 min at 23 °C) must be verified across production lots.
FAQ
What standards does the CZY-6S comply with?
GB/T 4851, ASTM D3654-22, and JIS Z0237:2021.
Can the instrument be calibrated internally?
Yes—test plate flatness, weight mass, and timing accuracy are verifiable using NIST-traceable reference standards; calibration certificates are issued per ISO/IEC 17025-accredited procedures.
Is temperature control available as an option?
No—the CZY-6S is designed strictly for ambient-temperature testing per standard methodology; for elevated-temperature holding power evaluation, Labthink’s HT-6 model is recommended.
How is specimen preparation standardized?
Per GB/T 4851: specimens are cut to 25 mm width × 100 mm length, applied to the test plate using a 2000 g ±50 g roller at 300 mm/min under 10 N load, then conditioned for 20 min before loading.
Does the system support LIMS integration?
Yes—via optional API-enabled software module compatible with major Laboratory Information Management Systems using HL7 or ASTM E1384 protocols.
