Meeting the Noise Legislation on Industrial Equipment in France
Decree of 11 April 1972
The decree of 11 April 1972 has introduced stringent limitation on bystander noise of industrial equipment in France. The maximum permissible level of 80 dB(A) at 7 metres constitutes today's lowest limit imposed by any legislation.
The specificity of the decree is analyzed and an attempt has been made to review the situation from a manufacturer's standpoint.
Various difficulties encountered by the manufacturers have resulted in extensive development programs and longer lead time to produce the modified equipment. Thus, the effective date of 2 May 1973 initially adopted in the decree could not be met by most manufacturers, and general or individual deviations have been accepted by the Ministry of Protection of Nature and Environment. The general deviation of 21 December 1973 indicates ultimate dates of availability accepted for each machine.
The noise reduction on four wheel drive loaders is presented as an actual example of application of the decree.
