Le présent code d'essai acoustique s'applique à tous les matériels d'enfonçage et d'arrachage des pieux tels que définis au 4.27.4.1, c'est à dire marteaux batteurs et extracteurs dont l'énergie d'attaque peut atteindre au maximum 250 kNm et aux vibreurs, dispositifs statique d'enfonçage / arrachage des pieux pouvant atteindre une puissance maximale de 1000 kW de la source de puissance.
Pour les équipements situés au-dessus de ces limites, le présent code d'essai acoustique peut nécessiter des modifications pour s'adapter à des problèmes techniques associés à un essai sur un équipement de grande dimension. Dans de tels cas, les détails des modifications doivent être enregistré et consigné (voir également G.5).
Le présent code d'essai acoustique spécifie toutes les informations nécessaires pour effectuer la détermination, la déclaration et la vérification des caractéristiques de l'émission acoustique de cet équipement. Il spécifie les méthodes de mesure acoustique et les conditions d'installation, de fonctionnement et de montage qui doivent être utilisées pour l'essai.
NOTE Ce code d'essai acoustique n'est pas destiné à la comparaison exacte des niveaux de bruit engendrés par les différents types d'équipement (c'est à dire, marteaux batteurs comparés aux vibreurs).

Machinery shall be so designed and constructed that risks resulting from the emission of airborne noise are
reduced to the lowest level taking account of technical progress and the availability of means of reducing noise, in
particular at source.
NOTE Noise emission measurements carried out according to annex G are useful to achieve this goal.
When designing pile installation and extracting equipment, the available information and technical measures to
control noise at source shall be taken into account (see e. g. EN ISO 11688-1).
NOTE EN ISO 11688-2 gives useful information on noise generation mechanisms in machinery.
4.27.2 Noise reduction by protective measures
The following measures, where practicable, are suitable examples:
a cab as specified in 4.9;
enclosure of the engine(s);
exhaust mufflers.
NOTE Guideline for the design of cabs and enclosures can be found in EN ISO 15667.

NOTE Noise measurements and declaration can be carried out according to the relevant standard for this type of
equipment.
4.27.4.3 Non noise emitting equipment
This includes leaders as described in 1.3 a) and accessories as described in 1.3 c) except hydraulic power packs,
power generators.
There is no need to carry out noise measurement and declaration for this type of equipment.

Annex G
(normative)
Noise test code for pile installation and extracting equipment
Noise emission characteristics include emission sound pressure levels at workstations and the sound power level.
The use of this noise test code ensures reproducibility of the determination of the noise emission characteristics
within specified limits determined by the grade of accuracy of the basic noise measurement method used. Noise
measurement methods allowed by this standard are engineering methods (grade 2).
G.1 Scope and field of application
This noise test code is applicable to pile installation and extracting equipment as defined in 1.3b). This noise test
code is applicable for impact hammers and extractors up to a maximum striking energy of 250 kNm and to
vibrators, static pile pushing/pulling devices up to a power of 1000 kW of its power source.
For equipment above these limits this noise test code may have to be adapted to accommodate the practical
problems associated with the testing of large equipment. In such cases the details of adaptation shall be recorded
and reported (see also G.5).
This noise test code specifies all the information necessary to carry out the determination, declaration and
verification of the noise emission characteristics of this equipment. It specifies noise measurement methods,
installation, operating and mounting conditions that shall be used for the test.
NOTE This noise test code is not intended for an exact comparison of noise levels generated by different types of
equipment
(i. e. impact hammers versus vibrators).
G.2 Installation and operation of source under test (see clause 6 of EN ISO 3744:1995)
G.2.1 Common requirements (see 6.1 of EN ISO 3744:1995)
The following general requirements apply in addition to the specific requirements given in G.2.2 for particular pile
installation and extracting equipment.
G.2.1.1 Test site (see 6.2 of EN ISO 3744:1995)
The test site can be any location, e. g. indoors or outdoors, at (manufacturers) test yard or on an actual job site,
provided that the background noise and acoustic environmental requirements of EN ISO 3744 are satisfied.
G.2.1.2 Test-pile or test-stand (see 6.2 and 6.3 of EN ISO 3744:1995)
The equipment shall be operated mounted on a test-pile or on a test-stand. The test- pile, if any, shall be a steel
pipe pile.
The test-stand shall allow a normal operation of the equipment according to the manufacturers specifications.
As far as practicable, the effect of background noise from the environment including that from any power source
shall be minimised and subsequently corrected by calculation (see G.3.3).
