The work of preparing International Standards is normally carried out through ISO t

8、echnical 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 clos

9、ely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees is to prepare International Standards. Draft

10、International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.Attention is drawn to the possibility that some of the elements of this document

11、 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.ISO 13926-3 was prepared by Technical Committee ISO/TC 76, Transfusion, infusion and injection, and blood processing equipment for medical and phamaceutical use.ISO 13926 consists of

The ratio of thickness of the single layers shall be agreed upon between the supplier and the user.4.3 The diameter of the rubber discs shall be such that a sufficient pre

24、ss-fit in the aluminium cap is achieved and that the discs cannot fall out.4.4 If not otherwise specified, general dimensional tolerances shall be in accordance with ISO 3302.4.5 The surface of the discs can be structured in order to avoid sticking.2 ISO 2012 All rights reservedBS ISO 13926-3:2012IS

25、O 13926-3:2012(E)5 Designation Seals can be designated according to their type (see Clause 3 and Figure 1). The designation shall be expressed as the word “Seal”, followed by a reference to this part of ISO 13926, followed by the nominal size, followed by the type letter.EXAMPLE Designation of a sea

27、ly lacquered.6.2 DiscDiscs shall be made from the elastomeric formulation originally tested and approved by the end user. The manufacturer of the discs shall ensure conformance of each delivery with the type sample and compliance with previously agreed functional and compendial requirements.The elas

28、tomeric material shall withstand two sterilization cycles when autoclaving in saturated steam at (121 2) C for 30 min without impairment of its function under the conditions of normal use. In case of other sterilization methods, e.g. irradiation, the suitability of the material shall be evaluated.7

29、Requirements7.1 GeneralThe requirements specified in 7.2 to 7.4 represent minimum requirements which refer to the condition of the seals on receipt by the user.7.2 Physical requirements7.2.1 Hardness of the discThe hardness agreed between the manufacturer and the user shall not differ from the nomin

30、al value by more than 5 Shore A when tested in accordance with ISO 7619-1 on a special test specimen. Alternatively, the hardness can be tested on the discs according to ISO 48. If tested according to ISO 48, the micro-hardness shall not differ by more than 5 IRHD from the type sample.The manufactur

31、er should provide suitable test specimens upon requests.7.2.2 FragmentationThe requirements and test method specified in ISO 8871-5:2005, 4.2, shall apply, using a needle with an outer diameter of 0,4 mm, conforming to ISO 7885:2010, 5.3 (butt end).

By

36、 means of a suitable device, a force is applied to the seal during a defined time interval. Any observed leakage is recorded.The leakage test of the seals and the plunger stoppers (see ISO 13926-2) can be combined.A.2 ApparatusA.2.1 Cartridge cylinders with a silicone-treated inner surface in accord

37、ance with ISO 13926-1.A.2.2 Seals to be tested.A.2.3 Plunger stoppers in accordance with ISO 13926-2.A.2.4 Suitable equipment to prepare water-filled cartridges.A.2.5 Cartridge holder, for example, as described in ISO 11608-3.A.2.6 Device, capable of applying a force as calculated in accordance with

38、 A.3.2.A.3 ProcedureA.3.1 Take 10 cartridges and fill them, using the seals to be tested, with water that is as air-free as possible. NOTE The water can be replaced by a coloured solution in order to improve the visibility of the leakage.A.3.2 Place the first cartridge, mounted in the cartridge hold

39、er (A.2.5), into the pressurizing device (A.2.6), and apply a force, F, as calculated in accordance with Formula (A.1) for 1 min.F = 0,64 N/mm2 d2(A.1)whereF is the force to be applied, in newtons;d is the inner diameter of the glass cylinder, in millimetres, in accordance with ISO 13926-1 (in ISO 1

40、3926-1, the inner diameter of the glass cylinder is designated d2)Check for leakage at the seal.SAFETY PRECAUTIONS Adequate safety measures should be in place to protect the operator.A.3.3 Repeat the operation described in A.3.2 on the remaining cartridges.
