The work of preparing International Standards is normally carried out through ISO technic
26、al 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. ISO collaborates closely wi
27、th the International Electrotechnical Commission (IEC) on all matters of 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
28、for the different types of ISO documents should be noted. This document 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 righ
29、ts. ISO shall not be held responsible for identifying any or all such patent 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

32、sed. It also incorporates the Amendment ISO 9626:1991/Amd 1:2001.The main changes to the previous edition of ISO 9626 introduced by this revision are the following:a) addition of specifications for stainless steel needle tubing for metric sizes 0,18 mm, 0,2 mm 0,23 mm and 0,25 mm and to reflect the
33、introduction of thinner tubing to allow greater comfort when injecting, particularly for infants and in paediatric use;b) addition 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
34、 means of specifying the steels to be used;e) revision of the table of tubing dimensions and stiffness parameters.Annex A, Annex B, Annex C, Annex D and Annex E form an integral part of this International Standard.4DIN EN ISO 9626:2016-12 EN ISO 9626:2016 (E)IntroductionGuidance on transition period
35、s for implementing the requirements of this International Standard is given in ISO/TR 19244.5DIN EN ISO 9626:2016-12 EN ISO 9626:2016 (E)1 ScopeThis International Standard applies to rigid stainless steel needle tubing suitable for use in the manufacture of hypodermic needles and other medical devic
36、es 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-use device.T
37、his 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 tubing in this
38、 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 and are indisp
39、ensable for its application. For dated references, only the edition cited applies.

The chosen materials shall be in accordance with the requirements indicated in this International Standard. Selection of specific stainless steel material shall be m
43、ade in consideration with the intended use, e.g. long-term contact with drugs and should consider biocompatibility requirements.NOTE Suitable biocompatibility requirements can be found in ISO 10993-1.5 Requirements5.1 GeneralFor the selection of tubing for a specific application and intended use, a
44、risk based approach shall be applied.5.2 Surface finish and visual appearanceWhen examined by normal or corrected vision, the outside surface of the tubing shall be smooth and free from defects.Surface finish specifications may be different based on the final function of the medical device; in such
45、cases, the medical device manufacturer should prepare specific specifications for surface finishing.When examined by normal or corrected vision, the needle tube shall appear straight and of regular roundness.5.3 CleanlinessWhen examined by normal or corrected vision, the surfaces of the tubing shall
46、 be free from metal soil and processing agents.Cleanliness specifications may be different based on the final function of the medical device; in such cases, the medical device manufacturer should prepare specific specifications for cleanliness.5.4 Limits for acidity and alkalinityWhen determined wit
47、h a laboratory pH meter and using a general purpose electrode, the pH value of an extract prepared in accordance with Annex A shall be within one pH unit of that of the control fluid.5.5 Size designationTubing size shall be designated by the nominal outer diameter, expressed in millimetres (i.e. the
48、 designated metric size), corresponding gauge size (e.g. G31 or 31G), and by wall thickness.EXAMPLE 0,25 mm (31G) ETW.5.6 DimensionsThe dimensions of tubing shall be as given in Table 1.7DIN EN ISO 9626:2016-12 EN ISO 9626:2016 (E)Table 1 Dimensions of tubingDesignated metric sizemmGaugeODMINmmODMAX
