Introduction
Improvement of working conditions is a permanent concern in industry. Noise is a main part of it.
It is not possible to measure noise emitted by blowpipes in any working conditions. Noise can change
according to working position, type of piece to be made, etc.
Testing conditions described in this document are standardized reference conditions, essential for
comparisons between blowpipes.
This document applies to give noise values while the blowpipe is working. Employer has to make an
integration of the noise which the worker is submitted to during his working time.
This document proposes indications allowing, according to the type of work, a calculation approach of noise
received by a person (see annex A).
