25、dards bodies (ISO member bodies). The work of preparing International Standards 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 org
26、anizations, governmental and non-governmental, in liaison with ISO, also 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
27、 in the ISO/IEC Directives, Part 2. The main task of technical committees 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
28、 % of the member bodies casting a vote. Attention is drawn to the possibility 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. ISO 9142 was prepared by Technical Committee ISO/TC 61, Plast
29、ics, Subcommittee SC 11, Products. This second edition cancels and replaces the first edition (ISO 9142:1990), of which it constitutes a minor revision.

30、conditions for testing bonded joints 1 Scope This International Standard describes laboratory ageing conditions under which adhesive joints may be exposed to various environmental influences climatic or chemical for the purpose of assessing the effects of such influences on certain properties. The a
31、geing conditions are applicable to bonded assemblies and may be used to constitute a set of tests for the evaluation of an adhesive. The results obtained using the procedures described in this International Standard are not necessarily applicable to the determination of the service life of a bonded
32、assembly because there is no direct relation between the test results and the behaviour of a bonded assembly over a period of time under service conditions. However, for certain specific applications, experience with the procedures may enable a correlation to be established. NOTE The ageing conditio
33、ns should preferably be related to the specific application of the adhesive. 2 Normative references The following referenced documents are indispensable for the application of this document.

The test specimens shall be prepared in accordance with the requirements of the appropriate
41、 ISO standard test method. Prepare a sufficient number of specimens to provide homogeneous sets of samples for testing and to provide control samples. The following International Standards, which do not constitute an exhaustive list, are applicable: ISO 4587, ISO 4588, ISO 6238. 5.2 Conditioning Spe
42、cimens shall be conditioned in the conditioning chamber (4.1) for a minimum duration of 24 h before being subjected to ageing. The conditioning shall be carried out after the adhesive has been cured in accordance with the materials specification or the methods specified by the manufacturer of the ad

44、ecimens to the environmental conditions as defined in Annex A to Annex F, as required. 6.3 Tests after ageing Determine the properties after ageing in accordance with the procedure(s) of the appropriate standard(s). Unless there are indications to the contrary in the Annexes, condition test specimen
45、s in the conditioning chamber (4.1) for (3 1) h in the case of specimens exposed at a relative humidity higher than 50 %, for at least 24 h for all other specimens, before determining the properties. In addition to the test results, all changes visible during the ageing and testing periods, includin
46、g mode of failure, shall be noted. 6.4 Controls For control purposes, a representative group of specimens shall be kept in the conditioning chamber (4.1) for the period of time covered by the ageing conditions selected. 7 Expression of results For properties that can be measured, the results obtaine
47、d are expressed as either absolute values or a relative variation with respect to the initial value. For properties that cannot be measured, the nature of the effects observed shall be noted, e.g. rupture between the substrate and adhesive, failure of cohesion of the adhesive joint due to partial or
48、 total corrosion of the substrate beneath the adhesive, etc. NOTE It may be worth verifying that the variation in a measured property is caused only by the ageing process from the following three values: A the value of the property measured before accelerated ageing; B the value of the same property measured on the co
