ISO 6855-2:2012 モペット—ガス状排気ガスと燃料消費量の測定方法—パート2：テストサイクルと特定のテスト条件 | ページ 2

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, Part 2.

The main task of technical committees is to prepare International Standards. 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.

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

ISO 6855-2 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 23, Mopeds.

ISO 6855-2 cancels and replaces ISO 6855:1983 and ISO 7859:2000, both of which have been technically revised.

ISO 6855 consists of the following parts, under the general title Mopeds — Measurement method for gaseous exhaust emissions and fuel consumption:

• Part 1: General test requirements
• Part 2: Test cycles and specific test conditions
• Part 3: Fuel consumption measurement at a constant speed

Introduction

This part of ISO 6855 has been prepared to provide details of the typical test cycles for measurement of exhaust gas and fuel consumption. The measurements can be carried out by referring to this part of ISO 6855 and ISO 6855-1.

1 Scope

This part of ISO 6855 defines test cycles for measurement for gaseous exhaust emissions from mopeds, as well as for determining the fuel consumption of mopeds as defined in ISO 3833, equipped with a spark ignition engine (four-stroke engine, two-stroke engine or rotary piston engine).
