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.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

Introduction

The technical committee on biogas (ISO/TC 255) was established in 2011 in order to:

— provide liberalization and facilitation for international trade of biogas systems;

— contribute to international co-operation on technical regulations, standards and assessment

procedures;

— curb discriminatory technical requirements as the main form of trade protectionism; and

— reduce and eliminate the technical barriers for international trade of biogas systems.

This International Standard about biogas systems is applicable for biogas production by anaerobic

digestion, biogas conditioning, biogas upgrading and biogas utilization. The main purpose of this

document is the sa
