IS 17419 : 2025 Metallic Materials - Ductility Testing - High Speed Compression Test for Porous and Cellular Metals (ISO 17340 : 2020, MOD)

Revised Standard from Last Update.

NATIONAL FOREWORD

This Indian Standard (First Revision) which is modified adoption of ISO 17340 : 2020 'Metallic materials - Ductility testing - High speed compression test for porous and cellular metals' issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Mechanical Testing of Metals Sectional Committee and approval of the Metallurgical Engineering Division Council.

This standard was first published in 2020. The portions given in dotted underlines are the matters not specified in the corresponding international standard. A list of technical modifications is given in National Annex C.

Porous and cellular metals have attractive properties due to their unique cell morphology. When they are used as impact energy absorbing components in automotive structures, knowledge of their highspeed compressive properties is necessary for industrial design. The high-speed compressive deformation behaviour of porous and cellular metals is quite different from their static compressive properties. Testing methods for static compressive deformation are, therefore, insufficient for characterization of high-speed compressive deformation. Standardization of a testing method for the high-speed compressive behaviour of porous and cellular metals is required.
