ASTM D3330 is a major peel testing standard that outlines the requirements for determining the peel adhesion properties of pressure-sensitive tapes such as surgical, electrical, packing, and duct tape. The standard includes 6 different methods (A-F) for measuring peel adhesion with both 90° and 180° peel tests. This guide is designed to introduce you to the basic elements of ASTM D3330 testing, including an overview of the equipment, software, and specimens needed.

A peel test is a mechanical test used to measure the properties of an adhesive bond between two substrates. The test applies a tensile force to a flexible substrate bonded by an adhesive to either another flexible substrate — such as tape, thin film, or rubber — or a rigid substrate such as metal, plastic, or composite. Key results include initial peak force, average force over the seal, and peel strength expressed as average force per unit width.

ASTM D903 is a common tensile test used to evaluate the peel or stripping characteristics of adhesively bonded materials used in a wide variety of applications in an even wider range of industries. Some examples of materials tested to ASTM D903 are plastic films, adhesive labels, and waterproofing materials.

Instron’s 6800 Series high-force testing systems are built to handle the most demanding testing applications. These systems are built with durable work surfaces, fortified against shock and vibration, and designed to reduce ingress from composite shards, rebar scale, and other debris — ensuring performance in some of the most demanding laboratory environments. Internal electrical and mechanical hardware have been isolated from the test area, while an abrasion-resistant coating is applied to the 12mm metal work surface for increased durability. Instron’s 6800 Series high-force testing systems are built to perform and built to last.

The Instron® Automated XY Stage for the ElectroPuls test instrument is designed for repetitive and multilocation durability testing. It can easily be adapted to suit many different testing scenarios with many different specimens, devices, and components, including electronic devices, touch sensitive panels, keyboards, performance footwear, and clothing.

Instron’s CT6 can be configured as an automated solution for the required testing of syringes. Break loose and glide force testing constitutes the bulk of syringe testing and is used to determine the real-world forces required to operate the syringe. Cobots can be placed separately or in-lined to improve throughput and efficiency in both of these applications.

In this webinar, we cover tips and best practices around strain and force transducers for universal testing machines. Our discussion includes a look at settings in Bluehill® Universal software as well as an overview of relevant hardware properties. We review a range of topics, including differences between various displacement measurements and how they’re treated in Bluehill, what a composite strain measurement is, how to set up a transverse strain extensometer, the importance of pretest limits, accuracy ranges for load cells and extensometers, when to change data acquisition rates, and more.

Instron’s CT6 offers the benefits of automation without the additional complexity of a fully automated testing system.

Instron’s® CT6 can be configured as an automated solution for the required testing of auto-injection devices — providing the benefits of automation without the additional complexity of a fully automated testing system. Designed to accommodate auto-injectors with varying geometries, this system allows you to measure a variety of critical data points including cap removal, activation force, injection time, injection mass/volume, and lock out force of the needle shield — all within a single test method.
