Introduction

Machinery supplied by electrical power or containing radiation sources may emit radiation or generate electric

and/or magnetic fields. The radiation emissions will vary in frequency and magnitude.

EN 12198-1 contains the general principles of risk assessment of radiation emission by machinery.

EN 12198-3 contains details of protective measures for avoiding or reducing radiation exposure of persons by

reducing emissions and requiring the provision of information.

Designers should identify the radiation hazards arising from machinery in accordance with the general principles

set out in EN 12198-1. In order to assess the risks and categorize the radiation emissions, designers need to

quantify the hazards.
Measurements are made in accordance with the following clauses in order to :
check the level of safety integration in the design of machinery ;
give a basis for the categorization according to 7.1 of EN 12198-1:2000 ;

assess the ability of machinery to be operated, set and maintained without any hazard to persons when setting

and maintenance operations are carried out under the conditions specified by the manufacturer ;

detect and measure, any radiation leakage ;

determine areas where radiation emissions may create a health and safety hazard ;

enable potential users to make comparisons of the radiation emission from different machines.

In case of particular difficulties, measurements can be supplemented by duly justified calculations.

Annex A gives information about the techniques of measurement of the different types of radiations. The standard

techniques will be specified in other standards as they are developed. Other methods and detectors can be

developed, their omission from this annex does not exclude their use.

If no standard measurement techniques exists, then an accepted scientific procedure should be applied and

appropriate details given.
This document is a type B standard as stated in EN 1070.

The provisions of this document may be supplemented or modified by a type C standard.

NOTE For machines which are covered by the scope of a type C standard and which have been designed and built

according to the provisions of that standard, the provisions of that type C standard take precedence over the provisions of this

type B standard.

3.1
operating conditions

conditions existing, including operating parameters, during the mode or phase of operation of the machine under

test
3.2
no-load operation

operation during which the machinery operates without any processed material in place, with all its components

and special auxiliaries in operation (pumps, hydraulic set, suction system, etc.) and all moving parts in action

(spindles, tables, carriages, etc.) within the limits of its possibilities
3.3
operation under load

operation during which the machinery is running in an operational way with processed material and with all its

components and special auxiliaries
3.4
phase of operation
time interval during which the machine performs a particular function
3.5
operating cycle

complete sequence of phases of operation from the introduction of the processed material to its removal or transfer

to the next workstation
3.6
measurement time
the period during which radiation measurements are made
---------------------- Page: 6 ----------------------
EN 12198-2:2002 (E)

This will be specified by both the duration of the measurement and the point in time related to the phase of

operation of the machine at which the measurement is made
3.7
averaging period

period over which the characterization assessment shall be made. The measured emissions are time averaged as

appropriate in order to take into account any variation in emission over this averaging period

4 Classification of radiation
Classification of radiation is given in clause 4 of EN 12198-1:2000.

Machinery shall be so designed and constructed that any emission of radiation is limited to the extent necessary for

its operation and that the effects on exposed persons are non-existent or reduced to non-dangerous proportions

(see EN 292-2:1991, annex A, subclause 1.5.10).
