ASTM D4846 Auto Textile Button Snap Pull Compression Fastener Tensile Tester

The ASTM D4846 is a standard test method developed by the American Society for Testing and Materials (ASTM). It is specifically designed for testing the performance of button snap fasteners used in automotive textiles. The test method, known as the "Auto Textile Button Snap Pull Compression Fastener Tensile Tester," provides a standardized procedure for measuring the pull-off strength and compression resistance of button snap fasteners.

The purpose of this test is to evaluate the strength and durability of button snap fasteners when subjected to tensile forces and compressive loads. It helps assess whether these fasteners can withstand the mechanical stresses encountered in automotive applications, such as repeated opening and closing of textile components like seat covers, headliners, or door panels.

The test is typically conducted using a specialized testing machine specifically designed for this purpose. The tester applies controlled tensile and compressive forces to the button snap fastener, measuring the maximum load it can withstand before failure or detachment.

By following the ASTM D4846 standard, manufacturers and researchers can compare the performance of different button snap fasteners and ensure their compliance with specific quality and safety requirements for automotive textiles.
