9、O (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 interested in a subject for which a technical co
10、mmittee 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 Commission (IEC) on all matters of electro
11、technical 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 needed for the different types of ISO documents should be noted. This document was draf
12、ted 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 rights. ISO shall not be held responsible for identifying any or all such patent ri
13、ghts. 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). Any trade name used in this document is information given for the convenience of users and does not const

17、red.The existing test methods are not appropriate because the evaluation of the plastic-metal interface performance is difficult as the polymer material has a relatively low mechanical strength and therefore fractures outside the joints. Therefore, it is necessary to develop a methodology for the ev
18、aluation of the plastic-metal interface performance.A test method to evaluate accurately the adhesion interface performance or standardization of long-term evaluation under harsh environments is also necessary.The method in ISO 19095 is intended to ensure the integrity of the interface is realized t

20、valuation of the adhesion interface performance in plastic-metal assemblies Part 1: Guidelines for the approachSAFETY STATEMENT Persons using this part of ISO 19095 should be familiar with normal laboratory practice, if applicable. This part of ISO 19095 does not purport to address all of the safety
21、 problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and to ensure compliance with any regulatory conditions. It is recognized that some of the materials permitted in this part of ISO 19095 might have a negative environ
22、mental impact. As technological advances lead to more acceptable alternatives for such materials, they will be eliminated to the greatest extent possible. At the end of the test, care should be taken to dispose of all waste in an appropriate manner in accordance with local regulations.1 ScopeThis pa
23、rt of ISO 19095 specifies the evaluation methods for the adhesion interface performance in plastic-metal assemblies.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

In the absence of this information, the most ap
29、propriate set of conditions from ISO 291 shall be selected and the conditioning time is at least 16 h, unless otherwise agreed upon by the interested parties, for example, for testing at elevated or low temperatures.5 Apparatus5.1 Sealing testing machine5.1.1 Helium leak detectorThis is the mass spe
30、ctrometer-type leak detector using the helium gas as a tracer, in which the vacuum exhaust system for keeping the mass spectrometer in operational vacuum condition (5,0 104MPa) is built-in and is calibrated in accordance with ISO 3530.5.1.2 Exhaust systemThis system consists of a vacuum pump for eva
