Manual Tear Strength Tester

• 

I. Product Overview

TheManual Tear Strength Testeris a precision instrument designed to measure the tear resistance of materials using standardized methods such as the Elmendorf or tongue tear test. It evaluates the force required to propagate a tear in textiles, plastics, rubber, and composites, ensuring compliance with international quality standards.

• Type: Mechanical pendulum tear tester
• Test Standards: ASTM D1424 (Elmendorf), ISO 34 (Tongue method)
• Tear Modes:
  • Elmendorf:Single-edge tear propagation
  • Tongue:Central slit expansion
• Capacity: 50–5000 mN (adjustable via pendulum weights)
• Sample Size: 63×127mm (Elmendorf) / 50×200mm (Tongue)

II. Technical Specifications

III. Key Features

• Dual Test Modes:
  • Elmendorf Test:High-speed single-edge tear
  • Tongue Test:Simulates real-world stress cracks
• Advanced Features:
  • Digital force gauge (0.1N resolution)
  • Auto-zero calibration system
  • Anti-slip clamping jaws
• Manual Operation:
  • Cranks for pendulum lifting (no electricity required)
  • Ratchet safety lock
  • Modular weights for customization

IV. Compliance Standards

• ASTM D1424 (Textile tear resistance)
• ISO 34 (Plastics and rubber tear methods)
• EN ISO 6383-2 (Rubber tear strength)
• GB/T 3917.1 (Chinese textile standard)

V. Applications

1. Textiles:Evaluating fabric abrasion and tear resistance
2. Plastics:Testing film and sheet material durability
3. Rubber:Measuring tire tread and industrial hose strength
4. Forensic Analysis:Documenting material failure causes

Standard Operation Workflow:

1. Sample Preparation: Cut to specified dimensions
2. Clamping: Secure sample in vise with 50N force
3. Calibration: Zero-force adjustment via digital gauge
4. Testing: Release pendulum and record peak force
5. Analysis: Calculate tear energy (J/m²) or force (N)

Safety Precautions:

• Wear gloves when handling sharp-edged samples
• Avoid loose clothing near moving pendulum
• Secure weights to prevent slippage
