What Is Peel Testing?
A peel test is a basic form of mechanical testing that measures the properties of an adhesive bond. Peel tests involve applying a tensile force to a flexible substrate that is bound by an adhesive to either another flexible substrate (such as tape, thin film, or rubber) or a rigid substrate (such as metal, rigid plastic, or composite). Common results from a peel test are initial peak force, average force over the seal, and peel strength (average force per width of the specimen).
ASTM D3330: Test Method for Peel Adhesion of Pressure-Sensitive Tape
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.
ASTM D903 Peel or Stripping Strength of Adhesive Bonds
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.
