The work of preparing International Standards is
10、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 take part
11、in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical 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
12、 the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted 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 d
13、ocument may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. 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
14、.org/patents). Any trade name used in this document is information given for the convenience of users and does not constitute an endorsement.For an explanation on the meaning of ISO specific terms and expressions related to conformity assessment, as well as information about ISOs adherence to the WT
15、O principles in the Technical Barriers to Trade (TBT) see the following URL: Foreword - Supplementary informationThe committee responsible for this document is ISO/TC 61, Plastics, Subcommittee SC 11, Products.ISO 19095 consists of the following parts, under the general title Plastics Evaluation of
16、the adhesion interface performance in plastic-metal assemblies: Part 1: Guidelines for the approach Part 2: Test specimens Part 3: Test methods Part 4: Environmental conditions for durabilityiv ISO 2015 All rights reservedBS ISO 19095-2:2015ISO 19095-2:2015(E)IntroductionStructures of heterogeneous
17、materials are being manufactured in the automobiles and aerospace industry sectors where higher safety margins are required.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 mechan
18、ical strength and therefore fractures outside the joints. Therefore, it is necessary to develop a methodology for the evaluation of the plastic-metal interface performance.A test method to evaluate accurately the adhesion interface performance or standardization of long-term evaluation under harsh e
19、nvironments is also necessary.The method in ISO 19095 is intended to ensure the integrity of the interface is realized through the interface and that traceability of the value improves the data comparison.This part of ISO 19095 defines the appropriate form of test pieces when considering plastic-met
20、al interfaces that cannot be evaluated by the existing ISO standards. ISO 2015 All rights reserved vBS ISO 19095-2:2015BS ISO 19095-2:2015Plastics Evaluation of the adhesion interface performance in plastic-metal assemblies Part 2: Test specimensSAFETY STATEMENT Persons using this part of ISO 19095
21、should be familiar with normal laboratory practice, if applicable. This part of ISO 19095 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 appropriate safety and health practices and to ensure compliance with a
22、ny regulatory conditions. It is recognized that some of the materials permitted in this part of ISO 19095 might have a negative environmental impact. As technological advances lead to more acceptable alternatives for such materials, they will be eliminated to the greatest extent possible. At the end
23、 of the test, care should be taken to dispose of all waste in an appropriate manner in accordance with local regulations.1 ScopeThis part of ISO 19095 specifies the test specimens for the evaluation of the adhesion interface performance in plastic-metal assemblies.2 Normative referencesThe following
