ASTM D5170

ASTM D5170 is the ASTM standard for the Standard Test Method for Peel Strength (“T” Method) of Hook and Loop Touch Fasteners. It provides a technical basis for evaluating how strongly these fastener systems resist separation under a peel load. That makes it useful for comparing product performance, supporting quality control, and helping buyers and manufacturers assess whether a fastener is suitable for a given application. The standard is especially relevant when consistent peel behavior matters.

ASTM D5170 standard overview

The ASTM D5170 standard focuses on a peel strength test using the “T” method for hook and loop touch fasteners. In practical terms, it is designed to measure the force required to separate the engaged fastener components under controlled conditions. This type of test is commonly used to create repeatable results for product evaluation and specification work. ASTM D5170 helps define a common testing approach so results can be compared more reliably across materials, suppliers, and production lots.

Where is ASTM D5170 used?

This standard is typically used wherever hook and loop touch fasteners are selected, tested, or specified for products that depend on dependable closure performance. It is relevant to manufacturers, laboratories, procurement teams, and quality groups that need a consistent way to measure peel strength. ASTM D5170 may also support incoming inspection, supplier qualification, and product development when evaluating how a fastener behaves under separation loads in regular use or handling.

Practical importance of ASTM D5170

ASTM D5170 matters because peel strength can affect usability, retention, and overall product performance. A standardized test method helps reduce variation in evaluation methods and supports more consistent decisions during compliance checks and quality control. It can also help organizations compare product samples, confirm specifications, and lower the risk of selecting a fastener that is too weak or unnecessarily difficult to open. For technical purchasing and engineering review, it provides a clearer performance benchmark.
