The work of preparing International Standards is normally carried out through ISO techn
13、ical 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
14、with 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 neede
15、d 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 r
16、ights. 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).

Reference should be made, for example to the ISO
20、9000- series, in conjunction with ISO 13485.The sampling plans and acceptance quality limits (AQLs) given in this International Standard are for referee testing. The AQLs represent the maximum tolerable level of defects in the products. As diaphragms are intended for re-use, manufacturers should str
21、ive for entirely defect-free product.Manufacturers can devise and apply additional and alternative quality control measures for their use and after production. These methods can differ among manufacturers. ISO 2014 All rights reserved vBS ISO 8009:2014BS ISO 8009:2014Mechanical contraceptives Reusab

27、initionsFor the purpose of this document, the terms and definitions given in ISO 2859-1 and the following apply.3.1lotbatchcollection of diaphragms of the same design, colour, shape, size, and formulation, manufactured at essentially the same time, using the same process, common lots of raw material
28、s, common equipment and personnelNote 1 to entry: The size of a lot is not specified in this International Standard, but it can be specified by a purchaser as part of a purchasing contract. Depending on the method of manufacture, multiple sizes can be produced in a defined lot/batch. In such cases,
29、traceability can be maintained by using both the lot number and the size.INTERNATIONAL STANDARD ISO 8009:2014(E) ISO 2014 All rights reserved 1BS ISO 8009:2014ISO 8009:2014(E)4 SamplingSampling and establishment of the sampling plan shall be carried out as described in ISO 2859-1.NOTE It is necessar
30、y to know the lot size in order to derive from ISO 2859-1 the number of samples to be tested. The lot size varies among manufacturers, and is regarded as part of the process and quality controls used by the manufacturer.5 ClassificationDiaphragms shall be classified into the following types:a) Type
31、1: Coil-spring diaphragm, also known as a helically wound diaphragm.b) Type 2: Flat-spring diaphragm, also known as a flat-leaf diaphragm, watch-spring diaphragm, or Mensinga diaphragm.c) Type 3: Arcing-spring diaphragm, also known as an arcing-bend diaphragm or bow-bend diaphragm.6 MaterialsThe dia
32、phragm, excluding the spring, shall be made of a natural or silicone rubber compound.For any new product or following a significant change to the formulation or manufacturing process, biocompatibility assessments shall be conducted in accordance with ISO 10993-1. Testing for cytotoxicity, in accorda
33、nce with ISO 10993-5, and for irritation and sensitization, in accordance with ISO 10993-10, shall be conducted. Spermicides applied at the time of use are exempt from this requirement. Where practicable, manufacturers should take steps to recommend spermicides that minimize irritant effects. Accred
34、ited laboratories shall be used for all biocompatibility testing. Regulatory bodies might also specify local requirements and require results to be interpreted by a qualified toxicologist. Any toxicologists assessment report shall state that the product is safe under normal conditions of use.NOTE Ma
35、ny latex products that have been established as safe, including diaphragms and medical gloves, can exhibit a positive cytotoxic response when tested according to ISO 10993-5. While any cytotoxic effect can be of concern, it is primarily an indication of potential for in vivo toxicity, and a diaphrag
36、m cannot necessarily be determined to be unsuitable for use based solely on cytotoxicity data.7 Design7.1 GeneralThe diaphragm shall consist of a dome and an integral peripheral rim. The dome of the diaphragm and the portion forming the rim shall be one continuous film.7.2 RimThe rim of the diaphrag
37、m shall be reinforced with a spring, which shall be sufficiently rigid to hold the rim in a flat, circular configuration.7.3 Reinforcing springThe reinforcing spring shall be completely encapsulated and centrally located within the rim.7.4 Spring endsThe ends of the spring shall be joined in such a
38、manner that the joint does not project through the surface of the rim.2 ISO 2014 All rights reservedBS ISO 8009:2014ISO 8009:2014(E)7.5 Dome and rimThe dome and rim shall have a uniform, smooth, and non-tacky finish.8 Dimensions8.1 DiameterThe nominal diameters of preferred sizes shall be 55 mm, 60
39、mm, 65 mm, 70 mm, 75 mm, 80 mm, 85 mm, 90 mm, 95 mm, and 100 mm.When tested in accordance with Annex A, the two diameter measurements shall not differ by more than 4 % of the nominal size. The mean of these two measurements, called diaphragm diameter, shall equal the nominal size within a tolerance
40、of 2 mm.Examine 13 diaphragms of each size. No diaphragm diameter shall fall outside the limits.8.2 Dome thicknessWhen tested in accordance with Annex B, the thickness of the diaphragm dome at the thinnest point measured shall not be less than 0,20 mm.9 Tensile properties of the dome9.1 Tensile stre
41、ngthWhen tested in accordance with Annex C, the median tensile strength of 13 diaphragms of each size shall not be less than the values given in Table 1.When tested in accordance with Annex D, the median tensile strength of 13 oven-treated diaphragms of each size shall not be less than the values gi
42、ven in Table 1.9.2 Elongation at breakWhen tested in accordance with Annex C, the median elongation at break of 13 untreated diaphragms of each size shall not be less than the values given in Table 1.When tested in accordance with Annex D, the median elongation at break of 13 oven-treated diaphragms

45、rom compression, of each diaphragm shall not be lower than 55 % and not greater than 85 % of the original diameter.After the 1 000th compression, the diameter along the axis of compression shall be at least 90 % of the value measured before the test.After the 1 000th compression, the rubber film sha
46、ll show no signs of deterioration when examined by normal or corrected vision.The degree of twist after 1 000 compressions, measured in accordance with Annex F, shall be not more than 20.Manufacturers of diaphragms who are certified to the ISO 9001 quality management system or equivalent, and whose
47、suppliers are similarly certified, may use the repeated compression testing part of this method as a type test. In that case, lot-by-lot testing shall consist of a single compression, and measurement of the compression resistance.10.2 Twisting during compressionWhen tested in accordance with Annex F
48、, the diaphragm shall not show an angle of twist greater than 20.Each lot shall be sampled in accordance with ISO 2859-1:1999, General inspection level I, but at least according to code letter K.When tested in accordance with Annex F, the compliance level shall be an AQL of 1,0 %.11 Freedom from vis
