IEC 60071-5:2014 provides guidance on the procedures for insulation co-ordination of high-voltage direct current (HVDC) converter stations, without prescribing standardized insulation levels. This standard applies only for HVDC applications in high-voltage a.c. power systems and not for industrial conversion equipment. Principles and guidance given are for insulation co-ordination purposes only. The requirements for human safety are not covered by this standard. This International Standard cancels and replaces IEC TS 60071-5 published in 2002. On the basis of technical experience gained since the Technical Specification was published, sufficient consensus has emerged for transformation of the Technical Specification into an International Standard. The technical content is essentially the same as that contained in the Technical Specification with amendments mainly for user convenience. The structure of the document has been changed to allow division and subdivision into complete integral parts to facilitate comprehension and ease of referencing. In addition to the high level revisions above, the following main technical changes have been made with respect to the previous edition:
- arresters have been added to several locations to reflect some recent 800 kV HVDC scheme practice, along with their justifications, expected voltages, overvoltages and arrester stresses in service;
- significant changes have been made in Clause 8 - all subclauses on the characteristics, schemes, stresses and specification of arresters have been consolidated into a single entity, Clause 8;
- the implications of a smoothing reactor and of a neutral blocking filter located on the neutral bus (as on some recent 800 kV schemes), on coordination of arresters connected to the neutral end have been added;
- possible use of sacrificial arresters on the neutral bus is introduced to cater for excessive arrester energy in the rather unlikely event of a particular rare fault;
- all subclauses dealing with study tools and modelling details have been consolidated into Clause 10;
- creepage distances and clearances have been consolidated into Clauses 11 and 12, respectively, with more details added.

L'IEC 60071-5:2014 donne des lignes directrices sur les procédures pour la coordination de l'isolement des stations de conversion à courant continu haute tension (CCHT), sans imposer de niveaux d'isolement normalisés. La présente norme s'applique seulement aux applications CCHT dans des systèmes de puissance alternative à haute tension et pas aux matériels de conversion industriels. Les principes et les lignes directrices donnés sont destinés aux seules fins de la coordination de l'isolement. Les exigences concernant la sécurité des personnes ne sont pas couvertes par la présente norme.
La présente Norme internationale annule et remplace l'IEC TS 60071-5 parue en 2002. Suite à l'expérience technique acquise depuis la parution de la spécification technique, un consensus suffisant a émergé concernant la transformation de la Spécification technique en Norme internationale. Le contenu technique est essentiellement le même que celui de la Spécification technique avec des amendements principalement apportés pour la commodité de l'utilisateur. La structure du document a été modifiée pour permettre la division et la subdivision en des parties intégrantes complètes pour faciliter la compréhension et le référencement. Outre les révisions de haut niveau ci-dessus, les modifications techniques majeures suivantes ont été apportées par rapport à l'édition précédente:
- des parafoudres ont été ajoutés à plusieurs emplacements pour refléter une certaine pratique récente du schéma CCHT (courant continu à haute tension) de 800 kV, accompagnés de leur justification, des tensions attendues, des surtensions et des contraintes relatives aux parafoudres en service;
- des modifications majeures ont été apportées à l'Article 8 - tous les paragraphes relatifs aux caractéristiques, aux schémas, aux contraintes et aux spécifications des parafoudres ont été consolidés en une seule entité, l'Article 8;
- les implications d'une bobine d'inductance de lissage et d'un filtre de blocage neutre placé sur une barre de neutre (comme dans certains schémas récents de 800 kV), sur la coordination des parafoudres raccordés à l'extrémité neutre ont été ajoutées;
- l'utilisation possible de parafoudres sacrificiels sur la barre de neutre est introduite pour pourvoir à une énergie excessive des parafoudres dans l'éventualité plutôt peu probable d'un défaut rare particulier;
- tous les paragraphes traitant d'outils d'étude et de détails de modélisation ont été consolidés à l'Article 10;
- les lignes de fuite et les distances d'isolement dans l'air ont été respectivement consolidées à l'Article 11 et à l'Article 12, avec plus de détails ajoutés.

ISO 9117:1990(E) Foreword ISO (the International Organization for Standardization) is a worldwide federation of national Standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Esch 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, govern- mental and non-governmental, in liaison with ISO, also take part in the work. ISO 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 Interna- tional Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard ISO 9117 was prepared by Technical Committee ISO/TC 35, Painfs and varnishes. Annex A forms an integral patt of this International Standard. 0 ISO 1990 All rights reserved.

INTERNATIONAL STANDARD ISO 94 17:1990(E) Paints and varnishes - Determination of through-dry state and through-dry time - Method of test 1 Scope This International Standard is one of a series of Standards dealing with the sampling and testing of paints, varnishes and related products. lt specifies a test method for determining under Standard conditions whether a Single coat or a multi-coat System of paint or related material has, after a specified drying period, reached the through-dry state, i.e. a pass/fail test. The test pro- cedure may also be used to determine the time taken to achieve that state. 2 Normative references The following Standards contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publi- cation, the editions indicated were valid. All stand- ards are subject to revision, and Parties to agreements based on this International Standard are encouraged to investigate the possibility of ap- plying the most recent editions of the Standards in- dicated below. Members of IEC and ISO maintain registers of currently valid International Standards. ISO 48:1979, Vulcanized rubbers - Determination of hardness (Uardness between 30 and 85 IRHD).

For the purposes of this International Standard, a Single coating or a multi-coat System of paint or varnish or related material is considered to be through-dry when a specified gauze under specified pressure, torsion and time does not mark or darnage the film. 3.2 through-dry Urne: The period of time between the application of a coat to a prepared test Panel and the achievement of the through-dry state, as determined by the specified test procedure. 4 Requlred supplementary Information For any particular application, the test method specified in this International Standard needs to be completed by supplementary information. The items of supplementary information are given in annex A. 5 Principle Application, to a Substrate, of a coat of agreed thickness which is allowed to dry under specified conditions. Determination of the completeness of drying throughout the coat by examination of the surface of the coat after the application of a load, applied over a given area of the surface, and sub- sequent rotation of the load-applying face through 90”.
