New Standard from Last Update.

NATIONAL FOREWORD

The Indian Standard (Part 4) which is identical with ISO 22241-4 : 2009 ‘Diesel engines - NOX reduction agent AUS 32 - Part 4: Refilling interface’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on recommendation of the Petroleum and their Related Products of Synthesis or Biological Origin Sectional Committee and approval of the Petroleum, Coal and Related Products Division Council.

This Indian Standard is published in five parts. The other parts in this series are:

Part 1 Quality requirements

Part 2 Test methods

Part 3 Handling transportation and storage

Part 5 Refilling interface for passenger cars

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.
