Mastering the correct peel test procedure helps ensure that all results are dependable and comparable across various production and testing environments.
This comprehensive guide explains the complete peel strength testing process, outlines key elements of ISO 8510 and ASTM D1876 standards, and offers insights on selecting the right equipment, including peel strength tester price and finding a reliable peel strength tester manufacturer.
What Is Peel Strength Testing?
Peel strength testing evaluates the adhesive force between two bonded materials, such as plastic films, laminates, flexible packaging, metal foils, or textiles. The test determines the force required to separate these materials by peeling one layer from another at a specific angle and speed.
Two common types of peel tests are:
- T-Peel Test (ASTM D1876): Measures the force required to peel two flexible materials from each other in a “T” configuration.
- 180-Degree Peel Test (ISO 8510): Evaluates the adhesive bond strength by pulling one material away from the other at a 180-degree angle.
Overview of ISO 8510 and ASTM D1876 Standards
ISO 8510: Peel Test Standard for Adhesives
The ISO 8510 standard outlines a method for determining the peel strength of bonded assemblies, particularly for flexible materials. It specifies parameters like:
- Specimen preparation
- Test angle (commonly 180 degrees)
- Rate of testing
- Environmental conditions
- Test evaluation method
Key applications include:
- Bond strength in automotive interiors
- Laminated packaging films
- Surface-treated composite materials
ASTM D1876: Standard Test Method for T-Peel
ASTM D1876 is widely used in packaging and film industries. This test is ideal for evaluating the bond between two flexible adherends. Unlike ISO 8510, which often uses a 180-degree angle, ASTM D1876 involves a T-peel configuration, where both legs of the sample are flexible and pulled apart vertically.
Main considerations in ASTM D1876:
- Uniform adhesive bonding
- Standard width and length of test specimens
- Load applied through a universal testing machine
- Test speed typically set at 300 mm/min
Equipment Required for Peel Strength Testing
To perform reliable tests as per these standards, industries rely on precision-built peel strength tester. Pacorr’s peel strength tester is engineered with high-quality load cells, adjustable grips, and programmable speed control to meet all global testing norms.
Features to look for in a peel strength tester include:
- High-accuracy load cell with overload protection
- Digital display or computer interface for data analysis
- Variable speed settings to match ISO and ASTM conditions
- Adjustable fixtures and grips for flexible sample handling
- Auto-calibration and test history storage
Whether you're testing flexible laminates, coated materials, or medical packaging, a reliable peel strength tester manufacturer like Pacorr provides complete testing solutions that align with ISO 8510 and ASTM D1876.
Step-by-Step Peel Test Procedure (ISO 8510 and ASTM D1876)
Step 1: Sample Preparation
- Cut specimens as per standard: 25 mm wide and at least 150 mm long for ASTM D1876.
- For ISO 8510, the width and bonded area may vary but are generally within similar dimensions.
- Ensure the adhesive area is free from contamination (dust, oils, etc.).
- Bond the two materials using standard adhesive curing time and pressure.
Step 2: Equipment Calibration
- Calibrate the peel strength tester before testing.
- Verify the load cell and grip alignment.
- Set the required peel angle: 180 degrees for ISO 8510 or T-configuration for ASTM D1876.
Step 3: Mounting the Specimen
- Secure both ends of the specimen in upper and lower grips.
- Ensure the bonded area aligns with the centerline of the load path.
- Set the gauge length typically at 100 mm (or as specified).
Step 4: Test Execution
- Set crosshead speed to 300 mm/min for ASTM D1876 and 100–300 mm/min for ISO 8510.
- Begin the test and record force vs. elongation graph.
- Maintain uniform peel rate and angle throughout the process.
Step 5: Result Analysis
- Determine average peel strength over a specified length of peel.
- For ASTM D1876, use the arithmetic mean of forces over the unbonded section.
- For ISO 8510, calculate force per unit width (N/mm).
Benefits of Complying with ISO 8510 and ASTM D1876
1. Consistency in Results
Standardized procedures ensure test repeatability and eliminate variability across different testing environments.
2. Global Acceptance
Test reports based on ISO and ASTM standards are universally recognized, aiding export quality control and certification processes.
3. Enhanced Product Development
Insight into bonding strength allows R&D teams to optimize adhesives and materials for better performance.
4. Risk Mitigation
Weak bonds can lead to product failure. Peel strength testing helps eliminate potential adhesive-related issues in production.
