Specialized Fixtures and Grips for Tear, Peel, and Puncture Testing

These specialized grips and fixtures handle tear, peel, puncture, pull-through, buckle, and other non-standard mechanical tests where conventional tensile or compression grips are not suitable. They are configured to match specific material behaviors and specimen shapes.

They extend a testing machine to tests that standard grips cannot perform. To match a set to your work, request a personal quote.

Peel testing setups include 90-degree peel fixtures and climbing drum peel fixtures for evaluating bond strength in adhesives, laminates, tapes, and layered assemblies. A peel test reports the average force per unit width needed to separate the bonded layers.

This is how adhesive and laminate bond quality is quantified. See our standards and certification.

Tear, peel, puncture, and pull-through tests apply load in specific directions and geometries that flat jaws or platens cannot reproduce. The specialized fixtures create the exact motion and support each test needs.

Using the right fixture is what makes these results valid and repeatable. To discuss your test, talk to our team.

Tear testing grips are used for plastic films, fabrics, and other flexible sheet materials to study tear propagation. They hold the specimen so a starting tear can be driven through it in a controlled way.

Tear resistance is a key property for packaging and textile films. Explore the full grips and fixtures range.

Yes. Alongside the standard tear, peel, and puncture setups, custom configurations are available for tests that fall outside conventional methods, matched to your specimen and how it is loaded.

This lets a lab test parts that do not fit off-the-shelf grips. To discuss a custom fixture, talk to our team.

Puncture fixtures include systems for geomembranes under ASTM D4833 and ball burst devices for textiles under ASTM D3787. A puncture or ball-burst test measures the force needed to push a probe through the material until it fails.

This characterizes how well a sheet resists penetration. See our standards and certification.

They cover several dedicated methods, including:

• ASTM D4833 for geomembrane puncture
• ASTM D3787 for textile ball burst
• ASTM D4501 for adhesive lap shear

Each fixture is matched to its specific method. See our standards and certification.

Custom shear fixtures include adhesive lap joint setups following ASTM D4501, which measure the shear strength of a bonded overlap. These are tailored to the joint and material being evaluated.

Lap shear is a standard way to compare adhesives. See our standards and certification.

Eyelet pull-through grips are used to test how well an eyelet, grommet, or similar feature resists being pulled out of the material. The fixture applies axial force to the feature to measure its pull-through resistance.

This matters for straps, tarpaulins, and reinforced fabrics. To set up a pull-through test, request a personal quote.

Buckle testing fixtures evaluate how buckles and similar closures perform under load, holding the component so force can be applied the way it is used. This measures the strength and reliability of the closure.

It is common in webbing, harness, and consumer product work. Explore the full grips and fixtures range.

They suit adhesives, laminates, tapes, plastic films, fabrics, geomembranes, textiles, and bonded assemblies. These are the materials whose tear, peel, and puncture behavior is not covered by standard tensile or compression tests.

One family therefore supports a wide set of non-standard tests. Explore the full grips and fixtures range.

They are used in packaging development, textile and film manufacturing, materials testing laboratories, and product engineering environments that require controlled testing beyond standard tensile or compression methods.

Each of these relies on repeatable non-standard testing. Explore the full grips and fixtures range.
