The thickness ratio of the single layers shall be agreed upon between the supplier and user.4.3 The diameter of the rubber discs shall be such that a sufficient press-fit in the aluminium cap is achieved
30、and that the discs cannot fall out.4.4 If not otherwise specified, general dimensional tolerances shall be in accordance with ISO 3302-1.DIN ISO 11040-3:2014-0575 DesignationSeals are designated according to their type (see Clause 3 and Figure 1). The designation shall comprise, in the following ord
31、er, 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 CapGeneral requirements for aluminium caps shall be in accordance with ISO 8872. In addition, the cap shall be anodized or sui
32、tably 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 conformance of each delivery with the type sample and the compliance with previously agreed functional and compendial requireme
33、nts.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 conditions of normal use. If other sterilization methods are used, e.g. irradiation, the suitability of the material shall be eva
34、luated.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.7.2 Physical requirements7.2.1 Hardness of the discThe hardness agreed between the manufacturer and the user shall not dif
35、fer 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 accordance with ISO 48. If tested according to ISO 48, the microhardness shall not differ by more than 5 IRHD from the type sa
36、mple.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, using a needle with an outer diameter of 0,4 mm that conforms to the butt-end requirements in ISO 7885:2010, 5.3.Schematic r

40、of ISO 11040 can be labelled with the designation given in Clause 5.DIN ISO 11040-3:2014-059Annex 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. An
41、y observed leakage is recorded.The leakage tests for seals and plunger stoppers (see ISO 11040-2) 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 prepar
42、e water-filled cartridges.A.2.5 Cartridge holder, e.g. as specified in ISO 9997 or ISO 11499.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 wat
43、er may 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 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 Adequa
44、te 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.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
