12、rewordISO (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. Each member body interested in a subject for which a tech
13、nical 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. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
14、 electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document
15、was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such p
16、atent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents). Any trade name used in this document is information given for the convenience of users and does n

30、m strands. The specifications for the conductors shall be according to Table 2 and shall be completed by material specifications. Elongation requirements shall be established by the agreement between the customer and the supplier. The finished cable shall meet the resistance requirements of Table 5

37、be considered to be approximate.When a.c. tests are performed, these shall be carried out at 50 Hz or 60 Hz. Applications at higher frequencies may require additional testing.4.6 OvensAn oven with air exchange, either natural or by pressure, should be used. The air shall enter the oven in such a way
38、 that it flows over the surface of the test pieces and leaves near the top of the oven. The oven shall have not less than 8 and not more than 20 complete air changes per hour at the specified ageing temperature.Forced air circulation, e.g. by a fan, inside the oven may be used. However, in case of d
