Overview
The ChemInstruments S-RT-30 Room Temperature 30-Bank Shear Adhesion Tester is an engineered solution for standardized evaluation of holding power and shear resistance of pressure-sensitive adhesives (PSAs) under ambient conditions. Designed in strict accordance with established international test methodologies—including ASTM D3654 (Procedure A), PSTC-7 (Procedure A), PSTC-14, and TLMI Test No. 7—the instrument implements a gravity-driven constant-load shear configuration to quantify adhesive creep deformation over time. Its 30-position parallel testing architecture enables statistically robust data collection across replicate specimens or multi-formulation screening, minimizing inter-test variability while maintaining full compliance with GLP-aligned laboratory workflows.
Key Features
- 30 independent shear test stations arranged in dual-tier configuration for high-throughput, concurrent evaluation
- Adjustable specimen mounting platform with precision leveling mechanism to ensure consistent 90° or user-defined angular orientation (down to 0°) relative to the vertical load axis
- Dual standard mass options: 100 g and 1000 g stainless steel weights, calibrated per NIST-traceable protocols for force accuracy
- Integrated battery-powered digital timer with 0.1-minute resolution and auto-stop functionality upon specimen failure
- Standardized stainless-steel test plates (50 mm × 75 mm; 2″ × 3″), manufactured to PSTC-specified surface finish and dimensional tolerances
- Self-contained 120 V AC / 60 Hz power system with internal surge protection—no external power conditioning required
- Modular accessory compatibility with ChemInstruments’ STA series: includes TP-23 test plates, STC-100 suspension clamps, and precision sample preparation tools
Sample Compatibility & Compliance
The S-RT-30 accommodates standard PSA-coated tapes, labels, and laminates mounted on rigid substrates including fiberboard (per PSTC-14), stainless steel, and aluminum. Specimen width is constrained by the 50 mm plate dimension, while length is governed by industry-standard 25 mm (1″) overlap requirements. All mechanical dimensions—including 115 mm standard weight drop height—conform precisely to ASTM D3654 and PSTC-7 geometric specifications. The system supports both static shear (holding power) and angular shear (e.g., 90° peel-to-shear transition) configurations, enabling correlation studies between adhesion geometry and long-term creep behavior. Documentation packages include calibration certificates traceable to ISO/IEC 17025-accredited laboratories, and the unit is routinely validated for use in FDA-regulated environments where ASTM-compliant PSA qualification is required under 21 CFR Part 11–aligned data integrity frameworks.
Software & Data Management
While the S-RT-30 operates as a stand-alone mechanical tester, its timed failure events are designed for seamless integration into LIMS and ELN platforms via optional RS-232 or USB-to-serial interface modules (sold separately). Time-to-failure values can be exported in CSV format for statistical analysis in JMP, Minitab, or Python-based reliability modeling suites. Audit trails—including operator ID, test date/time, weight selection, and angular setting—are manually recorded per GLP practice; optional barcode-scanned test plate IDs support traceability in GMP manufacturing validation protocols. Firmware updates (when applicable) comply with IEC 62304 software lifecycle standards.
Applications
- Quality control of medical device tapes, transdermal patches, and wound care dressings per ISO 20417 and USP
- Formulation development of acrylic, rubber, and silicone PSAs for packaging, automotive trim, and electronics assembly
- Regulatory submission testing for FDA 510(k) and CE Marking dossiers requiring PSTC-7 or ASTM D3654 evidence
- Accelerated aging correlation studies when paired with environmental chambers (e.g., 40°C/75% RH preconditioning per ASTM D1000)
- Supplier qualification audits where multi-lot shear consistency must be demonstrated across ≥30 replicates
FAQ
Does the S-RT-30 meet ASTM D3654 Procedure A requirements?
Yes—the instrument’s geometry, weight specifications, plate dimensions, and timing resolution fully satisfy all physical and procedural criteria outlined in ASTM D3654-22 Procedure A.
Can it perform tests at angles other than 90°?
Yes—its adjustable tilt mechanism supports angular shear testing from 0° to 90° in 5° increments, facilitating comparative analysis of directional adhesion dependence.
Is calibration documentation provided with shipment?
Each unit ships with a factory calibration report referencing NIST-traceable mass standards and certified timer accuracy; annual recalibration services are available through ChemInstruments’ ISO/IEC 17025-certified service centers.
What maintenance is required for long-term operational stability?
Routine cleaning of test plates and weight contact surfaces with isopropyl alcohol; biannual inspection of suspension clamp spring tension and leveling screw integrity is recommended.
Are replacement parts and accessories available globally?
Yes—TP-23 plates, STC-100 clamps, and calibrated weights are stocked in regional distribution hubs across North America, EMEA, and APAC, with lead times under 5 business days for standard items.
