What are the common compression test applications and test standards?

Abstract: 本文概述了压缩测试的基本原理、应用及相关标准。压缩测试涉及将样品放置在两个板之间，施加载荷以压缩样品，并测量其在压缩载荷下的机械性能。与拉伸试验相对，压缩测试重点测量样品在压缩过程中应变、应力、变形等参数，以评估其抗压强度、屈服强度、极限强度、弹性极限和弹性模量等性能。常见的应用包括多孔泡沫、钢材、水泥砂浆、异形石、电子元件及橡胶的压缩测试。文章还列出了多个相关标准，如ASTM D575（橡胶压缩试验）、ASTM D695（刚性塑料压缩性能测试）和ISO 844（刚性多孔塑料的压缩性能测定），这些标准为压缩测试提供了规范的方法和要求。

compression test

The test sample is usually placed between two plates, the applied load is distributed over the entire surface of the two opposite sides of the test sample, and the two plates are then pushed together by the Tensile Testing Machine, causing the sample to be compressed. A compressed sample typically shortens in the direction of the applied force and expands in the direction perpendicular to the force. Compression testing is essentially the opposite of the more common tensile testing.

The purpose of compression testing is to determine the mechanical properties of a material when subjected to a compressive load by measuring fundamental variables such as strain, stress, and deformation. Compression testing of materials allows determination of compressive strength, yield strength, ultimate strength, elastic limit and modulus of elasticity, among other parameters.
