ANNEX III

        TEST PROCEDURE

               1. INTRODUCTION

1.1.                            This Annex describes the methods of determining emissions of gaseous components, particulates and smoke from the engines to be tested. Three test cycles are described that shall be applied according to the provisions of Annex I, Section 6.2:

                —    the ESC which consists of a steady state 13-mode cycle,

                —    the ELR which consists of transient load steps at different speeds, which are integral parts of one test procedure, and are run concurrently,

                —    the ETC which consists of a second-by-second sequence of transient modes.

1.2.                            The test shall be carried out with the engine mounted on a test bench and connected to a dynamometer.

1.3.                            Measurement principle

              The emissions to be measured from the exhaust of the engine include the gaseous components (carbon monoxide, total hydrocarbons for diesel engines on the ESC test only; non-methane hydrocarbons for diesel and gas engines on the ETC test only; methane for gas engines on the ETC test only and oxides of nitrogen), the particulates (diesel engines only) and smoke (diesel engines on the ELR test only). Additionally, carbon dioxide is often used as
