Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, 3.

Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.

International Standard ISO 7168-1 was prepared by Technical Committee ISO/TC 146, Air quality, Subcommittee SC 4, General aspects.

ISO 7168 consists of the following parts, under the general title Air quality — Exchange of data:

• Part 1: General data format
• Part 2: Condensed data format

The first editions of the several parts of ISO 7168 together cancel and replace the first edition (ISO 7168:1985), which has been technically revised.

Annexes A, B and C form a normative part of this part of ISO 7168. Annexes D and E are for information only.

Introduction

For the interpretation or comparison of air quality data, the data themselves are usually not sufficient. Other information may be needed for a proper evaluation, e.g. basic information on the measurement, such as

• object of the measurements,
• place of sampling,
• date of sampling,or additional information, such as
• the measuring method used,
• sampling period of a single measurement,
• characteristics of the sampling site,
• validity of the data.In some cases, the user will need other information to be compared with the measured data in conformity with regulations or to enable certain complex processing operations to be performed, e.g.
• additional meteorological data,
• geographical and economic data,
• data on localized or diffuse atmospheric emissions.

The transmission of such information in a data file is not mandatory. Where necessary and possible, this supplementary information may be attached to a data file as comment.

ISO 7168-1 specifies the general data format for the exchange of air quality data. This general data format supports both the direct readability and the automated processing of data files. Each information presented in a data file prepared in accordance with ISO 7168-1 is related to a defined keyword and therefore consistently self-explanatory. The general data format is intended for the international exchange of air quality data.

ISO 7168-2 [1] specifies a condensed data format which is intended only for the exchange of data files between automatic data processing systems. A good knowledge of the file structure is necessary for the interpretation of these data files.

1 Scope

This part of ISO 7168 specifies a general format for the exchange of air quality data and related information. It defines mandatory and optional keywords to identify the data presented in a data file, and the values and formats of the data allocated to a keyword.

This part of ISO 7168 is recommended for the international exchange of air quality data. It is also intended for direct data import, e.g. into spreadsheets.
