L'IEC 60695-10-3:2016 spécifie un essai de déformation par réduction des contraintes de moulage. Elle est applicable aux matériels électrotechniques, y compris les parties composées de matériaux polymères. Cette méthode d'essai est destinée à évaluer les effets provoqués par la réduction des contraintes résiduelles induites par traitement, se produisant dans un assemblage polymère moulé d'un produit final. Cette réduction de contraintes se produit lorsque l'échantillon (sous ou hors tension) est exposé au conditionnement à une température définie pendant une période de temps définie. L'éprouvette d'essai est considérée comme ayant satisfait à l'essai si, après le conditionnement à température ambiante, elle satisfait aux critères d'essai définis. La présente publication fondamentale de sécurité est essentiellement destinée à être utilisée par les comités d'études dans le cadre de l'élaboration de normes conformément aux principes établis dans le Guide IEC 104 et le Guide ISO/IEC 51. Elle n'est pas destinée à être utilisée par les fabricants ou les organismes de certification. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- Références mises à jour;
- Matériel mis à jour;
- Termes et définitions ajoutés;
- et Bibliographie ajoutée.

Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work
of preparing International Standards is normally carried out through IS0
technical committees. Each member body interested in a subject for
which a technical committee has been established has the right to be
represented on that committee. International organizations, governmental
and non-governmental, in liaison with ISO, also take part in the work. IS0
collaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard IS0 11204 was prepared by Technical Committee
lSO/TC 43, Acoustics, Subcommittee SC 1, Noise.
Annex A forms an integral part of this International Standard. Annexes B,
C and D are for information only.

Introduction
0.1 This International Standard specifies a method for measuring the
emission sound pressure levels at a work station and at other specified
positions in the vicinity of a machine or piece of equipment. The method
specified in this International Standard follows the method specified in
IS0 11201 (engineering method), except for the following:
measurements are permitted in situ; and
a)
b) a method is specified for determining a local environmental correction
which yields results approximating those obtained in a free field over
a reflecting plane. This correction is used to derive the emission sound
pressure levels at specified positions, including work stations. If this
correction is less than the specified value, the results meet the engi-
neering grade of accuracy, but otherwise they meet the survey grade.
0.2 This International Standard is one of a series (IS0 11200 to
IS0 11204) which specifies various methods for determining the noise
emissions of a piece of machinery or equipment, or a sub-assembly of
such equipment (machine under test). IS0 11200 gives guidance on the
choice of the method to be used to determine the emission sound
pressure levels of machinery and equipment. It also gives details of Inter-
national Standards giving methods for the determination of sound power
levels.
