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
| Parameter | Specifications |
|---|---|
| Pendulum Range | 160–640 g (9 different weights) |
| Clamping Force | 50±5 N (adjustable via screw mechanism) |
| Tear Speed | 1.2±0.2 m/s (controlled by pendulum drop height) |
| Measurement Accuracy | ±1% FS (ISO 376 standard) |
| Dimensions | 800×400×1200mm (L×W×H) |
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
- Textiles:Evaluating fabric abrasion and tear resistance
- Plastics:Testing film and sheet material durability
- Rubber:Measuring tire tread and industrial hose strength
- Forensic Analysis:Documenting material failure causes
Standard Operation Workflow:
- Sample Preparation: Cut to specified dimensions
- Clamping: Secure sample in vise with 50N force
- Calibration: Zero-force adjustment via digital gauge
- Testing: Release pendulum and record peak force
- 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
