Industries du pétrole et du gaz naturel - Tubes d'acier pour tiges de forage - Spécifications (ISO 11961:1996)
L'IEC 60938-2:2021 s'applique à des inductances fixes conçues pour s’opposer aux perturbations électromagnétiques, qui sont connectées à un réseau d’alimentation à courant alternatif ou à une autre source d’alimentation dont la tension nominale ne dépasse pas 1 000 V (valeur eff.) en courant alternatif ou 1 500 V en courant continu avec une fréquence nominale qui ne dépasse pas 400 Hz.
La présente spécification intermédiaire se limite à des inductances fixes pour lesquelles des essais de sécurité sont souhaitables. Cela signifie que les inductances décrites conformément à la présente spécification sont, soit reliées à l'alimentation secteur, lorsque la conformité aux essais obligatoires de l’Annexe A est nécessaire, soit utilisées en d'autres positions du circuit pour lesquelles la spécification applicable à l'équipement indique que certains ou l'ensemble de ces essais de sécurité sont exigés.
Le présent document a pour objet de prescrire des exigences normalisées d'essais de sécurité ainsi que des valeurs assignées et caractéristiques préférentielles, qui permettent de choisir à partir de l’IEC 60938-1 les méthodes d'essai appropriées et de fournir des exigences générales de performance applicables aux inductances d'antiparasitage.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente.
- le programme d’essai pour les essais de performance a été supprimé; les essais de sécurité obligatoires et les essais de performance facultatifs sont énumérés dans un seul programme d’essai à l’Annexe B;
- les exigences relatives aux bobines d’arrêt à thyristor ont été supprimées;
- les exigences relatives aux matériaux sont alignées sur les normes IEC 60939-3 et UL 60939-3;
- les bobines d’arrêt à courant alternatif d’une tension jusqu’à 1 000 V et les bobines d’arrêt à courant continu d’une tension jusqu’à 1 500 V sont désormais incluses dans le Domaine d’application.

IS0 11961 :1996(E) @ IS0 Foreword IS0 (the International Organization for Standardization) is a worldwide fed- eration 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 collabo- rates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are cir- culated 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 11961 was prepared by Technical Committee ISO/TC 67, Materials and equipment for petroleum and natural gas indus- tries, Subcommittee SC 5, Casing and tubing. Annexes A to C form an integral part of this International Standard. SIST EN ISO 11961:2000
0 IS0 IS0 11961: 1996(E) Introduction This International Standard, based on API Spec 5D:1992, Specification for drill pipe, includes requirements of various nature. These are identified by the use of certain words or phrases. Shall is used to indicate that a provision is mandatory. - Should is used to indicate that a provision is not mandatory, but rec- ommended as good practice. - May is used to indicate that a provision is optional. In addition, in certain cases, this International Standard offers Alternative requirements. These offer different options, either: - At purchaser’s discretion in which case such option shall be men- tioned on the purchase order. These cases are recognized by the use of the words or phrases such as alternative or at purchaser’s dis- cretion. - At manufacturer’s discretion in which case such option shall be no- tified to the purchaser. Such cases are identified by the use of the phrase at manufacturer’s discretion. - By agreement between purchaser and manufacturer. Such cases are recognized by the use of the phrase by agreement between in- terested parties. This International Standard, when this phrase is used, intends to either waive the application of a requirement (either mandatory or rec- ommended) and leave it to both purchaser and manufacturer to use the requirement or not; or offer one (or several) alternative requirement(s), the is left to b 0th purchas er and manufacturer. selection of which SIST EN ISO 11961:2000
