IS 16052 : Part 4 : 2013/ISO 13765-4 : 2004 Refractory Mortars Part 4 Determination of Flexural Bonding Strength

Reaffirmed 2022

NATIONAL FOREWORD

This Indian Standard (Part 4) which is identical with ISO 13765-4 : 2004 ‘Refractory mortars - Part 4: Determination of flexural bonding strength’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Refractories Sectional Committee and approval of the Metallurgical Engineering Division Council.

This standard is published in various parts. Other parts in this series are:

Part 1 Determination of consistency using the penetrating cone method

Part 2 Determination of consistency using the reciprocating flow table method

Part 3 Determination of joint stability

Part 5 Determination of grain size distribution (sieve analysis)

Part 6 Determination of moisture content of ready-mixed mortars

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

c) In clause 7.1.2, number of test pieces have been mentioned. However, number of test pieces can also be taken by mutual agreement between the purchaser and the manufacturer. In clause 7.2, procedure for the drying of the test specimen is specified. Alternatively, the test specimen can be put into the drying oven at 110 ± 5ºC and held for 16 h.
