NYX HY-703-1 Cut Resistance Tester for Gloves, Shoe Uppers, and Protective Fabrics

Overview

The NYX HY-703-1 Cut Resistance Tester is an electromechanically controlled instrument engineered for standardized evaluation of cut resistance in personal protective equipment (PPE) materials—including knitted and woven gloves, shoe uppers, technical textiles, laminated composites, and elastomeric substrates. It operates on the principle of linear blade traversal under controlled normal force, conforming to the constant-load methodology defined in ISO 13997 (Method A) and ASTM F2992. Unlike pendulum-based systems (e.g., EN 388:2016’s TDM test), the HY-703-1 applies a precisely regulated vertical load while advancing a standardized tungsten-carbide blade across the specimen at a fixed velocity. This enables direct quantification of the force (in newtons) required to sever the material—yielding objective, traceable data essential for compliance reporting, material benchmarking, and QC release testing in PPE manufacturing and third-party certification laboratories.

Key Features

• Microprocessor-controlled actuation system ensuring ±1% repeatability in applied load (up to 100 N) and blade speed (150 mm/min, with fine-tuning capability)
• Integrated load cell with real-time force feedback and digital display for immediate verification of test parameters
• Modular blade holder accommodating standard ISO 13997-compliant tungsten-carbide blades (Type C, 25 mm length, 0.5 mm thickness)
• Adjustable specimen clamping mechanism with parallel jaw alignment to eliminate shear-induced artifacts during cutting
• Stainless-steel test chamber and corrosion-resistant structural frame for long-term stability in industrial lab environments
• Compliance-ready design: All mechanical and control components meet CE marking requirements for laboratory instrumentation (2014/30/EU EMC Directive and 2014/35/EU LVD)

Sample Compatibility & Compliance

The HY-703-1 accommodates flat specimens up to 100 mm × 100 mm and thicknesses from 0.2 mm to 6 mm—including coated fabrics, aramid-reinforced composites, nitrile-dipped gloves, leather uppers, and multi-layer cut-resistant laminates. Its test protocol satisfies mandatory requirements for classification under EN 388:2016 (Cut Level X, where X = 1–5, derived from ISO 13997 force thresholds), GB 24541–2009 (Chinese national standard for hand protection), and GA 633–2005 (Chinese public security industry standard for police gloves). The instrument supports full audit trails when operated in conjunction with compliant laboratory information management systems (LIMS), enabling adherence to GLP principles and facilitating FDA 21 CFR Part 11–aligned electronic record workflows where validated software interfaces are deployed.

Software & Data Management

While the base HY-703-1 operates via standalone front-panel controls, optional USB- or RS-232–enabled data logging modules allow seamless export of force-vs.-displacement curves, peak cut-through force (N), and blade travel distance (mm) to CSV or Excel-compatible formats. Raw data files include timestamp, operator ID, sample ID, and calibration certificate reference—supporting traceability per ISO/IEC 17025:2017 clause 7.7. For regulated environments, NYX provides documentation packages (IQ/OQ protocols, calibration certificates traceable to NIM China, and uncertainty budgets) upon request. Firmware updates maintain alignment with evolving revisions of ASTM F2992M and ISO 13997 Annex B guidance on blade wear compensation.

Applications

• Pre-certification screening of glove prototypes against EN 388 Cut Level 4 and 5 performance targets
• Comparative analysis of edge-cutting durability across competing fiber architectures (e.g., HPPE vs. stainless steel filament blends)
• Quality assurance testing of shoe upper materials subjected to abrasion and lateral blade contact in occupational footwear
• Root-cause investigation of cut failure modes in composite PPE—correlating force profiles with SEM imaging of blade–fiber interaction zones
• Supporting technical documentation for CE marking dossiers and ANSI/ISEA 105–2016 compliance submissions

FAQ

Does the HY-703-1 comply with the latest revision of ISO 13997?

Yes—the instrument implements Method A (constant load) as specified in ISO 13997:2015 and includes provisions for blade replacement verification per Clause 6.3.

Can it be used for testing non-woven medical gowns?

Yes, provided specimens meet minimum dimensional and tensile stability requirements; users must validate clamping pressure to prevent slippage during traversal.

Is calibration traceable to national standards?

All factory calibrations are performed using force standards certified by the National Institute of Metrology (NIM), China, with full uncertainty statements provided in the Certificate of Calibration.

What maintenance is required for long-term accuracy?

Biannual verification of load cell linearity and blade alignment is recommended; NYX supplies alignment jigs and certified reference weights for in-house checks.

Are consumables such as blades available through authorized distributors?

Yes—NYX-certified ISO 13997 Type C tungsten-carbide blades (batch-tested for hardness and edge geometry) are supplied with full lot traceability and CoA documentation.
