Revised Standard from Last Update.

NATIONAL FOREWORD

This Indian Standard (Fifth Revision) which is identical to ISO 7438 : 2020 ‘Metallic materials - Bend test’ 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 1960 and subsequently revised in 1974, 1985, 2012 and 2019. The fifth revision of this standard has been undertaken to align with the latest version ISO 7438 : 2020 to harmonize it with the latest developments that have taken place at international level.

The main change compared to the previous edition is the addition of new Annex B, describing bending test at plane strain condition.
