IS 12571 : 2025/ISO 3995 : 2023 Methods for Determination of Green Strength by Transverse Rupture of Rectangular Compacts of Metallic Powder
Revised Standard from Last Update.
NATIONAL FOREWORD
This Indian Standard (First Revision) which is identical to ISO 3995 : 2023 'Metallic powders - Determination of green strength by transverse rupture of rectangular compacts' issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Powder Metallurgical Materials and Products Sectional Committee and approval of the Metallurgical Engineering Division Council.
This standard was published in 1988. This revision has been brought out to align with the latest version of ISO 3995 : 2023 under dual numbering system to harmonize it with the latest developments that have taken place at international level.
This document covers a test method that may be used to measure the transverse rupture strength of a compacted but unsintered (green) test specimen produced from lubricated or unlubricated metal powders or powder mixtures.
The text of ISO standard has been approved as suitable for publication as in Indian Standard without deviations. Certain terminologies and conventions are, however, not identical with those used in Indian Standard. Attention is especially drawn to the following:
a) Wherever the words 'International Standard' appear referring to this standard, it should be read as 'Indian Standard'; and
b) Comma (,) has been used as a decimal marker while in Indian Standards the current practice is to use a point (.) as the decimal marker.
For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, expressing the result of a test or analysis shall be rounded off in accordance with IS 2 : 2022 'Rules for rounding off numerical values (second revision)'. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard.
