[Superseded IS/ISO 21573-1 : 2006]

New Standard from Last Update.

NATIONAL FOREWORD

This Indian Standard which is identical with ISO 21573-1 : 2014 ‘Building construction machinery and equipment - Concrete pumps - Part 1 Terminology and commercial specifications’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Construction Plant and Machinery Sectional Committee and approval of the Mechanical Engineering Division Council.

The Indian Standard supersedes IS/ISO 21573-1 : 2006 ’Building construction machinery and equipment - Concrete pumps — Part 1 Terminology and commercial specifications ’

The main changes in this revision are as follow:

a) editorial correction of numbering of table/figure reference;

b) addition of electric motor as drive power for concrete pump;

c) editorial corrections in figures to clarify part names and callout.

ISO 21573 consists of the following parts, under the general title ‘Building construction machinery and equipment — Concrete pumps’:

Part 1 Terminology and commercial specifications

Part 2 Procedure for examination of technical parameters.

In the adopted standard certain terminology and conventions are not identical with those used in Indian Standards; attention is drawn specially to the following:

a) Comma (,) has been used as a decimal marker while in Indian Standards the current practice is to use a point (.) as the decimal marker.

b) Wherever the words ‘International Standard’ appear, referring to this standard, they should be read as ‘Indian Standard’.
