HJ 518-2009Codes for Combustion Method Classification (English PDF)

Foreword

In order to promote the construction of environmental information, establish and improve the environmental information standard system to provide environmental information processing and exchange Technical support, ensuring the orderly processing and exchange of combustion type information, and unifying the classification and code of combustion methods.

Set this standard.

This standard specifies the classification and code of the combustion method.

This standard is the first release.

This standard was formulated by the Science and Technology Standards Department of the Ministry of Environmental Protection.

This standard was drafted. Information Center of the Ministry of Environmental Protection, Beijing University of Science and Technology.

This standard was approved by the Ministry of Environmental Protection on December 21, 2009.

This standard has been implemented since March 1, 2010.

This standard is explained by the Ministry of Environmental Protection.

3 Terms and definitions

The following terms and definitions apply to this standard.

Classification of combustion methods the process of distinguishing and classifying information attributes or characteristics classified according to the combustion method according to certain rules.

The combustion method establishes a certain classification system and the order of arrangement.

A collection of things that have a common attribute, also known as a category.

Classification system the whole of the interrelated categories formed after classification.

Combustion mode code A character or set of characters representing the burning mode category.

Combustion mode coding Based on the classification of combustion methods, the process of assigning codes to the combustion mode category.
