Grips & Fixtures

Introduction to ASTM C1161 Advanced ceramics are widely used in applications where high stiffness, thermal stability, wear resistance, and chemical inertness are required. Unlike metals or polymers, however, ceramics exhibit little to no plastic deformation and fail in a brittle manner. Because of this behavior, traditional tensile testing is often impractical or unreliable for ceramic materials. Instead, flexural strength testing  has become the primary method for characteri

This article provides a comprehensive technical overview of ASTM D1781, including the principles of the climbing drum peel test, required equipment, specimen preparation, grips and fixtures, data analysis, and best practices for achieving reliable and repeatable peel adhesion results.

ASTM D5458 provides guidance on test setup, equipment selection, and procedural considerations that help laboratories generate repeatable, comparable, and defensible tensile test data.

Selecting the correct grips for tensile testing is one of the most important — and most overlooked — decisions in any materials testing setup.
