Since 1955, under the auspices of the High Authority of the ECSC, the Committee for
Research on Industrial Health and Medicine has been examining the vast field of industrial
medicine in an attempt to define the liges of research to be fostered.
A subject which should be given pride of place in the study programmes and research
projects to be fostered, is the study of pneumoconiosis and emphysema.
These respiratory ailments affect a range of workers in ECSC industries, and this justifies
the importance attached to fostering research into the problems associated with these
diseases.
During the frequent exchanges of information between experts from the different
countries it was decided that, before these problems were tackled, an effort should be
made at Community level to standardize the studies. The experts agreed that this task
should be delegated to a Standardization Committee and theyd to furnish the
Committee with all the documentation and all relevant data. The Committee started
work immediately, and requested Mr. Cara, Director of the Laboratory of Experimental
Physics in Paris, to draw up a scheme to codify the rules spirographic practice, based
on the exchange of information within the Committee.
Mr. Cara was also requested to look into the principles of a calibration apparatus for
measuring physical and spirographic characteristics.
The normal ventilatory values were worked out at Community level thanks to the coop­
eration of many institutes which specialize in functional examinations. We should like
to thank Miss D. Brille, Miss D. Jouasset and Messrs. W. Bolt, G. Coppée, A. Houberechts,
F. Lavenne, A. Mey, M. Poisvert, L. Ruyssen, P. Sadoul, E. Sartorelli, G. Worth and O.
Zorn for the special help they gave in this work.
Several thousand reports containing data on ventilatory values and the biological
characteristics of normal test subjects, including age, occupation etc., were compiled
in Luxembourg.
Particular care was taken to exclude subjects who were ill or who showed signs of
sequelae of an illness.
Processing of the enormous volume of biometrie data was undertaken by departments
of the Commission of the European Communities, when the documents had been as­
sembled at the Directorate-General of Social Affairs. Mr. Cara processed the results and
derived rational formulae for determining reference values for the various ventilatory
parameters.
This Aide-Mémoire is the result of years of work. It is in a very handy form and we are
confident that it will be extremely useful particularly for practitioners engaged in industrial
medicine and specialists in pneumoconiosis.
