IS 1528 : Part 27 : 2024/ISO 22685 : 2021 Methods of Sampling and Physical Tests for Refractory Materials - Part 27 Method for Determination of Compressive Strength at Elevated Temperature of Refractory Products

ICS 81.080

MTD 15

NATIONAL FOREWORD

This Indian Standard (Part 27) which is identical to ISO 22685 : 2021 'Refractory products - Determination of compressive strength at elevated temperature' 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 Indian Standard has been issued in several parts. Other parts of this Indian Standard are:

Part 1 Determination of pyrometric cone equivalent (PCE) or softening point

Part 2 Determination of refractoriness under load

Part 3 Determination of spalling resistance

Part 4 Determination of cold crushing strength of dense shaped refractories products

Part 5 Method for determination of modulus of rupture at ambient temperature of dense and insulating shaped refractory products

Part 6 Determination of permanent linear change after reheating for shaped insulating and dense refractories

Part 7 Methods of sampling and criteria for conformity

Part 9 Determination of true density

Part 10 Determination of size of refractory bricks

Part 11 Determination of warpage

Part 12 Method for determination of bulk density and true porosity of shaped insulating refractory products

Part 13 Determination of resistance to carbon monoxide

Part 14 Determination of sieve analysis

Part 15 Method for determination of bulk density, apparent porosity and true porosity of dense shaped refractory products

Part 16 Determination of thermal conductivity according to hot-wire method (parallel)

Part 17 Shaped insulating refractory products - Determination of cold crushing strength

Part 18 Determination of creep in compression

Part 19 Determination of thermal expansion

Part 20 Determination of modulus of rupture at elevated temperature

Part 21 Determination of thermal conductivity according to hot-wire method (cross-array and resistance thermometer)

Part 22 Method for determination of permeability to gases of dense shaped refractory products

Part 23 Methods of test for dense shaped refractory products - Determination of resistance to abrasion at ambient temperature

Part 24 Monolithic refractory products - Determination of resistance to explosive spalling

Part 25 Determination of abrasion resistance at elevated temperature

Part 26 Method for determination of resistance to sulfuric acid of dense shaped refractory products

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.
