IS 3400 : Part 14 : Sec 3 : 2020/ISO 5600 : 2017 Methods of Test for Vulcanized Rubbers - Part 14 Adhesion of Rubber to Rigid Material - Section 3 Using conical shaped parts

New Standard from Last Update.

NATIONAL FOREWORD

This Indian Standard (Part 14/Sec 3) (Second Revision) which is identical with ISO 5600 : 2017 ‘Rubber — Determination of adhesion to rigid materials using conical shaped parts’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on recommendation of the Methods of Test for Rubber and Rubber Products Sectional Committee had been approved by the Petroleum, Coal and Related Products Division Council.

The first revision of this Indian Standard was published in 1984.

The need for a standard method for the determination of bond strength between rubber and metal has been felt for the standardization of quality in different rubber Products like resilient mounting and engine mounting. The reasons for failure of bonds in these articles are rather complicated in service, due to local stress concentration either by a suddenly imposed excessive shock or due to fatigue under different dynamic conditions. However, it was considered essential to formulate a standard method of test under Standard laboratory conditions to provide data for the development and control of rubber compounds and their methods of manufacture.

Three methods were prescribed in this standard: Method A covers the procedure for testing the strength of rubber to metal bonds by separation where the rubber part is adhering to a metal surface while method B, covers the procedure for measuring the force required to cause the rupture of a unit of standard dimensions, comprising rubber bonded to two parallel metal plates. Method C which has been included in this revision specifies a method for measuring the static vulcanized adhesion strength of rubber compound where test piece is composed of two conical ends of a rigid material joined by a cylinder of rubber. The first revision was based on ISO 813, ISO 814 and ISO 5600.

The Sectional Committee has decided to align IS 3400 (Part 14) with the latest International Standards available on the subject by adopting latest ISO 813 : 2016, ISO 814 : 2017 and ISO 5600 : 2017. As

this Indian Standard is already part of series of standards, it has been further decided to publish the three ISO standards as three sections of standard. The other sections in this series are:

Section 1 90° peel method

Section 2 Two-plate method

The text of ISO Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain terminologies and conventions 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’.

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.
