IS 18652 : 2024/ISO 12241 : 2022 Thermal Insulation for Building Equipment and Industrial Installations - Calculation Rules

ICS 91.140.01; 91.120.10

CHD 27

NATIONAL FOREWORD

This Indian Standard, which is identical to ISO 12241 : 2022 'Thermal insulation for building equipment and industrial installations - Calculation rules' issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Thermal Insulation Sectional Committee and approval of the Chemical Division Council.

This document gives rules for the calculation of heat-transfer-related properties of building equipment and industrial installations, predominantly under steady-state conditions. This document also gives a simplified approach for the calculation of thermal bridges.

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 in the International Standard, while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
