IS 3400 : Part 26 : 2025/ISO 1827 : 2022 Vulcanized Rubber - Methods of Test - Part 26 Determination of Shear Modulus and Adhesion to Rigid Plates - Quadruple-Shear Methods
NATIONAL FOREWORD
This Indian Standard (First Revision) which is identical to ISO 1827 : 2022 'Rubber, vulcanized or thermoplastic - Determination of shear modulus and adhesion to rigid plates - Quadruple-shear methods' issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Rubber and Rubber Products Sectional Committee and approval of the Petroleum, Coal and Related Products Division Council.
This standard was first published in 2019. This revision has been brought out to align it with the latest version of ISO 1827 in dual numbering system to make pace with latest developments that have taken place at international level.
The text of ISO standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions and terminologies are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:
a) Wherever the words 'International Standard' appear referring to this standard, they 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.
