11、BS ISO 3011:1997 BSI 09-1999iii Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body inter
12、ested 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 with the International Electrotechnical
13、 Commission (IEC) on all 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. Int
14、ernational Standard ISO 3011 was prepared by Technical Committee ISO/TC 45, Rubber and rubber products. This third edition cancels and replaces the second edition (ISO 3011:1981), which has been technically revised. Descriptors: Fabrics, coated fabrics, fabrics coated with rubber, fabrics coated wit

16、ncontrolled Copy, (c) BSI BS ISO 3011:1997 BSI 09-19991 WARNING Persons using this standard should be familiar with normal laboratory practice. This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user to establish app
17、ropriate safety and health practices and to ensure compliance with any national regulatory conditions. 1 Scope This International Standard specifies a method for the determination of the resistance of fabrics coated with rubber or plastics to ozone cracking under static conditions. The test is desig
18、ned to determine the relative resistance to cracking of fabric coated with rubber or plastics when exposed under static strain to air containing ozone in the absence of direct sunlight. Like all ageing tests, it should be considered as a means of comparing articles of the same composition and destin
19、ed for the same application, but not as an absolute criterion. It is preferable to limit the significance of the test by considering it only as a means of control when a fabric attains a resistance superior to a threshold given in comparison with a certain type of degradation. Taking these remarks i
20、nto account, the results obtained at the time of test cannot be taken as a prediction of the length of life of the product. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of pu
21、blication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the standards listed below. Members of IEC and ISO maintain regist

The effects of the ozone are assessed by measurement of the time at which the first crack appears or of the time of exposure during which no cracks appear, as appropriate. 4 Apparatus 4.1 Test chamber a
