La CEI 60027-7:2010 s'applique à la production, au transport et à la distribution de l'énergie électrique. Elle donne les noms et les symboles littéraux des grandeurs et unités. Elle fixe en outre des règles concernant les indices multiples et leur succession. Elle est une extension de la CEI 60027-1. Les symboles littéraux figurant déjà dans la CEI 60027-1 ne sont donc répétés que s'ils ont une signification particulière dans le domaine de la production, du transport et de la distribution de l'énergie électrique ou s'ils sont utilisés avec des indices particuliers dans ce domaine.

ISO 8033:1991(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 Inter- national Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard ISO 8033 was prepared by Technical Committee ISO/TC 45, Rubber and rubber products, Sub-Committee SC 1, Hoses (rubber and plastics). This second edition cancels and replaces the first edition (ISO 8033:1985), of which it constitutes a minor revision. 0 ISO 3991 All rights reserved.

INTERNATIONAL STANDARD ISO 8033:1991 (E) Rubber and plastics hose - Determination of adhesion between components 1 Scope Adequate adhesion between the various com- ponents of a hose js essential if it is to perform sat- isfactorily in Service. This International Standard specifies methods for the determination of the adhesion between lining and reinforcement, between cover and reinforce- ment and between reinforcement layers. lt covers all bore sizes and the following types of hose con- struction: - woven textile fabric - braided yarns - spiralled yarns - knitted yarns - circular woven yarns - textile cord fabric - braided wires - spiralled wires -- hoses containing a supporting helix 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 stan- dards 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 471:1983, Rubber - Standard temperatures, hu- midities and firnes for the conditioning and testing of test pieces. ISO 1826: 1981, Rubber, vulcanized - Time-interval between vulcanization and testing - Specification. ISO 5893:1985, Rubber and plastics fest equipmenf - Tenside, f7exural and compression types (constant rate of traverse) - Descripfion. ISO 6133:1981, Rubber and plasfics - Analysis of multi-peak traces obtained in determinations of tear strength and adhesion strength. 3 Principle Using test pieces of Standard dimensions, the ad- hesion strength between lining and reinforcement, between cover and reinforcement and between re- inforcement layers is measured under specified conditions. 4 Apparatus A test machine having the following characteristics is required. 4.1 The machine shall be power driven, equipped with a suitable dynamometer, capable of maintain- ing a substantially constant rate of traverse of the moving head during the test and fitted with an autographic recorder. It shall comply with the re- quirement for grade A of ISO 5893. . NOTE 1 An inertiaiess dynamometer should be used. 4.2 The grips shall be capable of holding the test piece without Slippage. NOTE 2 Self-tightening grips are recommended. 1 SIST EN 28033:2000
ISO 8033:1991 (E) For Strip test pieces, Provision shall be made to maintain the Strip in the appropriate plane of the grips during the test, for example by the attachment of sufficient weights to the free end of the test piece or by fitting a supporting plate, coated with a low friction material such as polytetrafluoroethylene (PTFE), to the non-driven grip. 4.3 For testing a ring test piece, a mandrel shall be provided that is a close sliding fit in the test piece. This mandrel shall be capable of being fitted into the driven head of the machine so that it will * rotate freely during the test (type 6). 5 Test pieces hoses amete of the sa rs are not me construction but of di comparable. 5.3 Test piece preparation 5.3.1 Type 1 Cut a ring 25 mm + 0,5 mm wide from the hose at right angles to its-longitudinal axis. Cut the ring transversely and open it out to form a Strip (see fig- ure 1). NOTE 3 The test pieces should be prepared by a method that does not Cause high temperatures due to the cutting blade. Where heat build-up might Cause a deterio- ration of properties, type 2, 3, 5 or 6 test pieces should be used. 5.1 Types of test piece 5.3.2 Type 2 Seven types of test piece are specified to cover the range of hose construction for methods and bore size normally encountered. 51.1 Type 1 Ring, tut from the hose 25 mm + 0,5 mm wide and - tut transversely to form a Strip. 5.1.2 Type 2 Strip, 160 mm x half the hose circumference. 51.3 Type 3 Ring, tut from the hose 35 mm + 2 mm wide and tut - transversely to form a Strip. 5.1.4 Type 4 Strip, 160 mm x half the hose circumference or 10 mm whichever is smaller. 51.5 Type 5 Strip, 160 mm long x half the hose circumference. 5.1.6 Type 6 Ring, 35 mm + 2 mm wide. - 5.1.7 Type 7 Strip, tut along a reinforcing helix, 25 mm + 0,5 mm - wide or the maximum obtainable. 5.2 Test piece selection Unless specified in the particular product Standard or otherwise
