SMS Stable Micro Systems TA.XTplus Texture Analyser for Leather Tensile and Tear Strength Testing

Overview

The SMS Stable Micro Systems TA.XTplus Texture Analyser is a high-precision, universal force measurement system engineered for mechanical property characterization of soft solids and viscoelastic materials. Designed around the fundamental principles of uniaxial compression, tension, and shear deformation under controlled displacement or force modes, the TA.XTplus delivers repeatable, traceable, and ISO 17025-aligned mechanical response data. In leather testing applications, it quantifies critical performance parameters—including tensile strength, tear resistance (e.g., ASTM D1894, ISO 3377-2), elongation at break, modulus, and stress relaxation—by applying programmable load profiles to standardized specimens using calibrated load cells (ranging from 5 N to 5000 N full scale) and precision crosshead movement (0.001 mm resolution). Its rigid frame architecture, low-inertia drive system, and real-time closed-loop feedback control ensure minimal thermal drift and high reproducibility across extended test sequences—essential for QC labs operating under GLP or ISO/IEC 17025 accreditation requirements.

Key Features

• Modular fixture ecosystem supporting ASTM D2209 (tear resistance), ISO 13934-1 (tensile strength), and ISO 2419 (leather tensile properties) compliant sample configurations
• Motorized crosshead with ±0.001 mm positional accuracy and programmable speed range from 0.01 to 2000 mm/min
• Integrated barcode scanning interface enabling one-touch recall of validated test methods—eliminating manual protocol selection errors
• Remote operation capability via iOS/Android mobile devices or tablets through secure HTTPS-based Exponent Connect software interface
• Automated post-test workflow: raw force–distance curves, derived metrics (peak load, energy to break, % elongation), and PDF reports auto-sent to preconfigured email addresses
• Compliance-ready audit trail: full electronic record retention including user ID, timestamp, instrument ID, calibration status, and method version—aligned with FDA 21 CFR Part 11 and EU Annex 11 expectations

Sample Compatibility & Compliance

The TA.XTplus accommodates standard leather specimens per ISO 2419 (dog-bone and strip geometries), as well as custom-cut samples for automotive upholstery, footwear, and glove-grade materials. Fixture options include pneumatic tensile grips, trouser-tear jigs, and oscillating bend testers for flex resistance assessment. All mechanical tests adhere to internationally recognized standards including ASTM D751 (coated fabrics), ISO 13934-1/2 (tensile properties), ISO 3377-1/2 (tear propagation), and EN 15987 (leather durability). Instrument calibration follows UKAS-accredited procedures traceable to NPL (National Physical Laboratory) reference standards; routine verification is supported by certified reference weights and dimensional gauges included in the SMS Calibration Kit.

Software & Data Management

Exponent Software v6.1.10 provides full method development, execution, and analysis functionality. Users may define multi-stage protocols (pre-test equilibration, ramp-to-load, hold, return, relaxation) with conditional logic (e.g., “stop on 95% force decay”). Raw data is stored in proprietary .exp format with embedded metadata (operator, date/time, environmental conditions, calibration certificate ID). Export options include CSV, Excel, and XML for LIMS integration. Over 400 peer-reviewed application notes—including leather-specific studies published in Journal of the American Leather Chemists Association and Textile Research Journal—are embedded within the software help system. All software updates, firmware patches, and validation documentation are distributed exclusively through SMS’s secure customer portal, accessible only to registered instrument owners.

Applications

• Quantification of tensile strength and elongation of bovine, ovine, and synthetic leathers during tanning process optimization
• Comparative tear resistance evaluation of finished leathers subjected to wet-state conditioning (ISO 2418)
• Assessment of fatigue-induced stiffness changes in automotive seat leathers after 50,000+ flex cycles
• Correlation of instrumental texture parameters (hardness, springiness, cohesiveness) with sensory panel scores in luxury goods QA
• Validation of adhesive bond integrity in laminated leather composites using peel and shear fixtures
• Stress relaxation profiling for predicting long-term dimensional stability in footwear uppers

FAQ

Is the TA.XTplus compliant with ISO/IEC 17025 requirements for accredited testing laboratories?
Yes—the system supports full traceability of measurements, includes documented calibration certificates traceable to NPL, and enables electronic signature-enabled report generation meeting ILAC-G8 and EURACHEM guidelines.
Can existing leather test methods from older SMS instruments be migrated to the TA.XTplus?
All legacy .exp files from TA.HDplus and TA.XT2i systems are fully backward-compatible with Exponent v6.x without conversion.
Does SMS provide on-site IQ/OQ/PQ documentation support for regulated environments?
Yes—qualified validation engineers supply GMP-compliant installation qualification (IQ), operational qualification (OQ), and performance qualification (PQ) packages upon request, including risk assessments and URS alignment.
How frequently must the load cell be recalibrated?
Annual recalibration is recommended; however, daily verification using the included 100 g and 1 kg traceable weights satisfies most internal QA protocols between formal calibrations.
