The work of preparing International St
30、andards 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-governmental, in liaison with ISO, also
31、 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 task of technical committee
32、s 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. Attention is drawn to the possib
33、ility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Amendment 1 to ISO 1431-1:2004 was prepared by Technical Committee ISO/TC 45, Rubber and rubber products, Subcommittee SC 2, Testing
34、and analysis.

35、DMENT ISO 1431-1:2004/DAM 1 ISO 2007 All rights reserved 1 Practice has shown that air used for generation of ozone or dilution in a discharge tube need not to be purified by passing over activated charcoal. 5.2 b) is therefore to be modified by replacing the first three sentences with a NOTE so it
36、will read: 5.2 Source of ozonized air The ozonized air shall be largely free of nitrogen oxides in order to avoid errors in the ozone concentration. One of the following items of apparatus shall therefore be used: a) ultra-violet lamp; b) silent-discharge tube. When utilizing the discharge tube, the
37、 use of oxygen, as opposed to air, is necessary in order to avoid the formation of nitrogen oxides. The ozonized oxygen or air can subsequently be diluted with air to attain the required ozone concentration. Air used for generation of ozone or for dilution shall first be purified by passing it over
38、activated charcoal and shall be free from any contaminants likely to affect the ozone concentration, the estimation of the ozone concentration or the cracking of the test pieces. The temperature of the source shall be kept constant to within 2 C. The ozonized air shall be fed from the source into th
39、e chamber via a heat exchanger to adjust its temperature to that required for the test and shall also be brought to the specified relative humidity (see 8.3). NOTE Interference by oxides of nitrogen, which theoretically can be produced in a discharge tube using air, is not expected at the low ozone concentrations specified.
