19、ation) 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 technical committee has been established has the right to be
20、 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 electrotechnical standardization.The procedures used to
21、 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 was drafted in accordance with the editorial rules of th
22、e 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 patent rights. Details of any patent rights identified dur
23、ing 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 not constitute an endorsement.For an explanation on the mea

25、, Devices for administration of medicinal products and catheters.This second edition cancels and replaces the first edition (ISO 9626:1991), which has been technically revised. It also incorporates the Amendment ISO 9626:1991/Amd 1:2001.The main changes to the previous edition of ISO 9626 introduced
26、 by this revision are the following:a) addition of specifications for stainless steel needle tubing for metric sizes 0,18 mm, 0,2 mm0,23 mm and 0,25 mm and to reflect the introduction of thinner tubing to allow greater comfortwhen injecting, particularly for infants and in paediatric use;b) addition
27、 of wall thickness designations beyond regular-walled and thin-walled tubing;c) addition of minimum inner diameters for additional items where possible;d) revision of the means of specifying the steels to be used;e) revision of the table of tubing dimensions and stiffness parameters.Annex A, Annex B

30、medical devices primarily for human use.This International Standard provides requirements and test methods for the tubes manufactured for needles as component used in medical devices. Additional performance testing on the tube aspect may be required when the component is incorporated in the ready-to
31、-use device.This International Standard specifies the dimensions and mechanical properties of steel tubing of designated metric sizes 3,4 mm (10 Gauge) to 0,18 mm (34 Gauge).It does not apply to flexible stainless steel tubing because the mechanical properties differ from those specified for rigid t
32、ubing in this International Standard. However, manufacturers and purchasers of flexible tubing are encouraged to adopt the dimensional specifications given in this International Standard.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document a
