8、7(E) IS0 Foreword IS0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for

9、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. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on al

10、l matters of electrotechnical standardization. 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. International Standard IS0

11、 8009-1 was prepared by Technical Committee ISOTTC 157, Mechanical contraceptives. IS0 8009 consists of the following parts, under the general title Reusable rubber contraceptive diaphragms: - Part 1: Classification, sampling and requirements - Part 2: Determination of size - Part 3: Determination o

18、sable rubber contraceptive diaphragms Part 1 : Classification, sampling and requirements 1 Scope This part of IS0 8009 gives a classification of, and specifies requirements for, reusable rubber diaphragms (hereafter called diaphragms) supplied in consumer packages for contraceptive use. This part of

19、 IS0 8009 does not cover other vaginal contraceptive barriers, such as those known as cervical caps, vaginal sponges and vaginal sheaths. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of IS0 8009. At the ti

20、me of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this part of IS0 8009 are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below.

28、59-1. It is necessary to know the lot size in order to derive from IS0 2859-1 the number of samples to be tested. The lot size will vary among manufacturers and is regarded as part of the process and quality controls used by the manufacturer. 5 Classification Diaphragms shall be classified into the

29、following types: Type 1: coil-spring diaphragm, also known as a helically wound diaphragm. Type 2: flat-spring diaphragm, also known as a flat-leaf diaphragm, watch-spring diaphragm or Mensinga diaphragm. Type 3: arcing diaphragm, also known as an arcing-bend diaphragm or bow-bend diaphragm. 6 Mater

30、ials The diaphragm, excluding the spring, shall be made of a rubber compound. The diaphragm and any lubricant, dressing material or powder applied to it should neither contain nor liberate substances in amounts that are toxic, sensitizing, locally irritating, or otherwise harmful under normal condit

31、ions of use and should not have a deleterious effect on the diaphragm. There should be no adverse reaction between the spring and the material from which the diaphragm is made, and the spring should not be harmful to the user under normal conditions of use. 7 Design 7.1 The diaphragm shall consist o

32、f 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 The rim of the diaphragm shall be reinforced with a spring, which shall be sufficiently rigid to hold the rim in a flat, circular configuration. 7.3 The reinforcing sp

33、ring shall be completely encapsulated and centrally located within the rim. 7.4 The ends of the spring shall be joined in such a manner that the joint does not project through the surface of the rim. 7.5 The dome and rim shall have a uniform, smooth, non-tacky finish. 8 Dimensions 8.1 Diameter The n

34、ominal diameters of preferred sizes are: 45mm, 50mm, 55mm, 60mm, 65mm, 70mm, 75mm, 80 mm, 85 mm, 90 mm, 95 mm, 100 mm and 105 mm. 2 Copyright International Organization for Standardization Provided by IHS under license with ISONot for ResaleNo reproduction or networking permitted without license fro
