ASTM D3330, ISO 813
Adhesion strength 90 degree peeling test fixture is a professional device used to measure the peel strength of adhesives at a 90° angle. It evaluates the resistance of the bonded interface to peeling by simulating a vertical peeling scenario. It tests the adhesion of tape or materials when peeled vertically and is suitable for bonding tests of rigid materials (such as PCBs) and flexible materials (such as copper foil circuits).

General introduction
Adhesion strength 90 degree peeling test fixture is a professional device used to measure the peel strength of adhesives at a 90° angle. It evaluates the resistance of the bonded interface to peeling by simulating a vertical peeling scenario. It tests the adhesion of tape or materials when peeled vertically and is suitable for bonding tests of rigid materials (such as PCBs) and flexible materials (such as copper foil circuits).
With the electronic universal testing machine, it can automatically calculates the maximum/minimum peel force and average peel strength.

ASTM D3330: Standard Test Method for Peel Adhesion of Pressure-Sensitive Tape
Testing the peel strength of bonded materials is one way to evaluate their adhesiveness. The peel strength is determined by applying a constant shear stress to the materials and calculating the resulting force multiplied by the bond surface width. Testing typically entails separating either two bonded flexible materials or a single bonded flexible material affixed to a stiff substrate.
Tape, adhesives, and flexible substrates like rubber, films, biomaterials, consumables, medical packaging, and more are often subjected to peel strength tests to describe their bonding strength. Various peel testing methods are available for a variety of materials.
90°-peel strength testing
The 90-degree peel test is a method for calculating the unit force required to tear apart bound materials at a 90-degree angle. It can be used to examine the binding between a flexible material and a hard substrate.

Standard
ISO 29862 Self adhesive tapes — Determination of peel adhesion properties
ISO 29862 specifies peel adhesion force of pressure-sensitive adhesive (PSA) tapes under controlled laboratory conditions. It covers four core 180° peel test methods plus two normative annexes for low-temperature and 90° peel testing, serving as a universal quality control and material comparison benchmark for adhesive tape manufacturers, laboratories and end users worldwide.
ISO 813 specifies a laboratory 90° peel method to determine the adhesion strength of a vulcanized or thermoplastic rubber strip deliberately bonded to a single rigid substrate plate, by measuring the force required to peel the rubber away at (nominally) 90° under a controlled crosshead speed. Results are expressed as N/mm (force ÷ bonded width) .
ASTM D3330 Standard Test Method for Peel Adhesion of Pressure-Sensitive Tape
ASTM D3330 for measuring peel adhesion of all types of pressure-sensitive adhesive (PSA) tapes, unifies six distinct test geometries to characterize interfacial bonding strength between PSA tape and substrates, tape backings, release liners, and transfer adhesive films, covering both 180° and 90° peel angles.
ISO 8510-1 — Adhesives — Peel test for a flexible-bonded-to-rigid test specimen assembly — Part 1: 90° peel
ISO 8510-1 specifies a 90° peel test for determining, under specified conditions, the peel resistance of a bonded assembly of two adherends where at least one adherend is flexible. The force is applied approximately normal (perpendicular) to the plane of the bond, through the separated part of the flexible adherend. The result is the average peel force (in newtons) over a defined length, which can be converted to peel strength per unit width.
