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 29042-3 was prepared by Technical Committee ISO/TC 199, Safety of machinery.

ISO 29042 consists of the following parts, under the general title Safety of machinery — Evaluation of the emission of airborne hazardous substances:

• Part 1: Selection of test methods
• Part 2: Tracer gas method for the measurement of the emission rate of a given pollutant
• Part 3: Test bench method for the measurement of the emission rate of a given pollutant
• Part 4: Tracer method for the measurement of the capture efficiency of an exhaust system

The following parts are under preparation:

• Part 5: Test bench method for the measurement of the separation efficiency by mass of air cleaning systems with unducted outlet
• Part 6: Test bench method for the measurement of the separation efficiency by mass of air cleaning systems with ducted outlet
• Part 7: Test bench method for the measurement of the pollutant concentration parameter

A room method for the measurement of the pollutant concentration parameter and a decontamination index are to form the subjects of future parts 8 and 9.

Introduction

The structure of safety standards in the field of machinery is as follows:

• a) type-A standards (basic safety standards) giving basic concepts, principles for design, and general aspects that can be applied to all machinery;
• b) type-B standards (generic safety standards) dealing with one safety aspect or one type of safeguard that can be used across a wide range of machinery:
  • type-B1 standards on particular safety aspects (e.g. safety distances, surface temperature, noise);
  • type-B2 standards on safeguards (e.g. two-hand controls, interlocking devices, pressure-sensitive devices, guards);

• c) type-C standards (machine safety standards) dealing with detailed safety requirements for a particular machine or group of machines.

1 Scope

This part of ISO 29042 specifies a test bench method for the measurement of the emission rate of a given airborne hazardous substance from a machine using a test bench under specified machine operating conditions.

The measurement of the emission rates of a given pollutant emitted from machines can serve for

• a) evaluation of the performance of a machine,
• b) evaluation of the reduction of pollutant emissions of a machine,
• c) comparison of machines within groups of machines having the same intended use (as defined by the function and materials processed),
• d) ranking of machines from the same group according to their emission rates, and
• e) determination of the state-of-the-art of machines with respect to their emission rates.

This part of ISO 29042 is not applicable to machinery manufactured before the date of its publication.
