The work

8、 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 represented on that committee. International organizations, governmental and non-governmen

9、tal, 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.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main

10、 task of technical committees is to prepare International Standards. Draft 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.Atten

11、tion is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

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

25、 shall be such that a sufficient press-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 3302-1.2 ISO 2012 All rights reservedBS ISO 11040-3:2012ISO 11040-3:2012(E)5 DesignationSeals

26、are designated according to their type (see Clause 3 and Figure 1). The designation shall comprise, in the following order, the descriptor “Seal”, a reference to this part of ISO 11040 and the type letter.EXAMPLE Designation of a seal of type A (i.e. trimmed):Seal ISO 11040-3 - A6 Material6.1 CapGen

27、eral requirements for aluminium caps shall be in accordance with ISO 8872. In addition, the cap shall be anodized or suitably lacquered.6.2 DiscsDiscs shall be made from the elastomeric formulation originally tested and approved by the end user. The manufacturer of the discs shall ensure the conform

28、ance of each delivery with the type sample and the compliance with previously agreed functional and compendial requirements.The elastomeric material shall withstand two sterilization cycles when autoclaving in saturated steam at (121 2) C for 30 min without impairment of its function under condition

29、s of normal use. If other sterilization methods are used, e.g. irradiation, the suitability of the material shall be evaluated.7 Requirements7.1 GeneralThe requirements specified in 7.2 to 7.4 constitute minimum requirements concerning the condition of the elastomeric seals on receipt by the user.7.

30、2 Physical requirements7.2.1 Hardness of the discThe hardness agreed between the manufacturer and the user shall not differ from the nominal value by more than 5 Shore A when tested in accordance with ISO 7619-1 on a special test specimen. Alternatively, hardness can be tested on the discs in accord

31、ance with ISO 48. If tested according to ISO 48, the microhardness shall not differ by more than 5 IRHD from the type sample.The manufacturer should provide suitable test specimens upon request.7.2.2 FragmentationThe requirements and test method of ISO 8871-5:2005, 4.2 and Annex B, shall apply, usin

36、)Annex A (normative) Leakage testA.1 PrincipleWater-filled cartridges are prepared using the seals to be tested. By means of a suitable device, a force is applied to the seal during a defined time interval. Any observed leakage is recorded.The leakage tests for seals and plunger stoppers (see ISO 11

37、040-2) can be combined.A.2 ApparatusA.2.1 Cartridge cylinders, in accordance with ISO 11040-1.A.2.2 Seals to be tested.A.2.3 Plunger stoppers, in accordance with ISO 11040-2.A.2.4 Suitable equipment, to prepare water-filled cartridges.A.2.5 Cartridge holder, e.g. as specified in ISO 9997 or ISO 1149

38、9.A.2.6 Pressurizing device, capable of applying a force of (30 1) N.A.3 ProcedureA.3.1 Take 10 cartridges and fill them with water until they are practically air-free using the seals to be tested.NOTE The water may be replaced by a coloured solution in order to improve the visibility of the leakage

39、.A.3.2 Place the first cartridge, mounted in the cartridge holder (A.2.5), into the pressurizing device (A.2.6), and apply a force of (30 1) N for 1 min. 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 de

40、scribed in A.3.2 on the remaining cartridges.A.4 Expression of resultsReport the number of leakages observed at the seal.Report whether the testing of the seals and plunger stoppers (see ISO 11040-2) has been combined.
