Cut Susceptibility Tester

The Cut Susceptibility Tester is designed to evaluate the resistance of photovoltaic module backsheets and surface materials to cutting, scratching, and abrasion under controlled mechanical loading. The system simulates long-term mechanical wear caused by installation, environmental movement, and external contact, providing quantitative assessment of backsheet durability and safety performance in accordance with photovoltaic module safety standards.

Application

(1) Cut susceptibility testing of photovoltaic module backsheets

(2) Abrasion resistance evaluation of PV polymer films and composite laminates

(3) Safety qualification testing for PV module rear-side insulation layers

(4) Durability comparison of different backsheet materials and coatings

(5) Quality control testing during PV module production

(6) Failure analysis and material research in photovoltaic laboratories

Standards

(1) IEC 61730-2 – Photovoltaic (PV) Module Safety Qualification – Requirements for Testing

(2) UL 1703 – Flat-Plate Photovoltaic Modules and Panels

(3) CE Certification (Conformité Européenne)

Features

(1) Multi-Directional Traction Design: Allows cut and scratch testing from any direction to reflect real installation and service conditions.

(2) Stable Mechanical Drive System: Ensures smooth and repeatable traction motion during long-duration abrasion tests.

(3) Closed-Loop Force Control: Maintains constant cutting force throughout the entire scratch path.

(4) Rigid Test Platform: Aluminum alloy tabletop minimizes deformation and improves result repeatability.

(5) Operator Safety Protection: Integrated emergency stop and force-limiting logic reduce operational risk.

(6) Automated Test Execution: Predefined test sequences reduce operator influence and improve test consistency.

Parameters

Accessories

(1) Indenters: 5× diamond indenters (10–50 μm tip radius)

(2) Sample Fixtures: 10× adjustable backsheet clamps (1–10 mm thickness)

(3) Consumables: Calibration-grade abrasion paper and replacement cutting blades

(4) Safety Equipment: Cut-resistant gloves (EN 388 Level 5), eye protection shield

(5) Software: ScratchTest Pro software license (Windows/macOS)

(6) Documentation: Multilingual quick-start guide and IEC/UL compliance certificates

Test Procedures

(1) Secure the backsheet or test specimen onto the test table using appropriate clamps.

(2) Install the cutting blade or diamond indenter and set the required traction force.

(3) Define scratch speed, travel direction, and test length via the touchscreen interface.

(4) Start the test and monitor real-time force and motion status.

(5) After completion, inspect the specimen and record cut depth or failure characteristics.

Maintenance Information

(1) Inspect cutting blades and indenters regularly and replace when worn.

(2) Clean the test table and traction mechanism after each test series.

(3) Verify force sensor calibration at scheduled intervals.

(4) Check drive belts, pulleys, and guide rails for smooth operation.

(5) Store the equipment in a dry, dust-free environment to maintain accuracy and service life.
