to:<\/p>\n<ul>\n<li><strong>Materials Covered<\/strong>: Natural and synthetic rubbers, elastomers.<\/li>\n<li><strong>Applications<\/strong>: Testing components such as O-rings, gaskets, and other compressible products.<\/li>\n<li><strong>Testing Conditions<\/strong>: Simulates real-world scenarios with specified loads and environmental conditions.<\/li>\n<\/ul>\n<p>This standard ensures that rubber materials can endure compression forces without significant deformation over time.<\/p>\n<h4><strong>Purpose of ASTM D395<\/strong><\/h4>\n<p>The primary purpose of ASTM D395 is to:<\/p>\n<ul>\n<li><strong>Measure Compression Set<\/strong>: Determine how much permanent deformation occurs after a material is compressed and then released.<\/li>\n<li><strong>Evaluate Durability<\/strong>: Assess whether rubber materials can maintain their intended function over time.<\/li>\n<li><strong>Support Material Development<\/strong>: Provide data for improving formulations and designs.<\/li>\n<\/ul>\n<h4><strong>Key Concepts in ASTM D395<\/strong><\/h4>\n<ol>\n<li><strong>\u538b\u7f29\u6c38\u4e45\u53d8\u5f62<\/strong>: The percentage of permanent deformation remaining after a compressive load is removed.<\/li>\n<li><strong>Recovery<\/strong>: The material&#8217;s ability to return to its original thickness.<\/li>\n<li><strong>Load Relaxation<\/strong>: Reduction in compressive stress over time.<\/li>\n<li><strong>Permanent Deformation<\/strong>: A critical measure of material failure in sealing applications.<\/li>\n<\/ol>\n<h4><strong>Types of ASTM D395 Methods<\/strong><\/h4>\n<p>ASTM D395 includes two methods for testing:<\/p>\n<ol>\n<li><strong>Method A (Plates)<\/strong>:\n<ul>\n<li>Samples are compressed between rigid plates.<\/li>\n<li>Suitable for general rubber materials.<\/li>\n<\/ul>\n<\/li>\n<li><strong>Method B (Disks)<\/strong>:\n<ul>\n<li>Samples are compressed using a cylindrical fixture.<\/li>\n<li>Commonly used for O-rings and seals.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n<p>The choice of method depends on the material&#8217;s intended application and testing requirements.<\/p>\n<h4><strong>Equipment Used in ASTM D395
