The work of preparing International Standards is normally carried out through ISO
8、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 in the work. ISO collaborates clo
9、sely 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 committees is to prepare International Standards. Dra
10、ft 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 possibility that some of the elements of this docu
11、ment may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 19813 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 1, Ignition equipment. BS ISO 19813:2006 Licensed Copy: London South Bank University, Lon

13、 high voltage boots on plug-top coils and pencil coils 1 Scope This International Standard specifies tests and requirements for all types of high voltage boots on plug-top coils and pencil coils. 2 Tests and requirements 2.1 General 2.1.1 General test conditions If not otherwise specified all tests
14、shall be carried out at room temperature (RT) (23 5) C. Each test sequence shall be started with unused test samples. Spark-plug insulator shall be manufactured in accordance with the customers requirements. The boot shall be positioned on the spark-plug insulator as defined by the customer. During
15、the whole test sequence, the boot shall be in the specified condition (with/without grease) as defined by the customer. 2.1.2 Visual examination 2.1.2.1 Test Before and after the tests in 2.2.1 and 2.2.2 respectively, carry out the visual examination with naked eye, corrected, if necessary, to give
16、normal strength of vision and normal colour perception, at the most favourable viewing distance and with suitable illumination. 2.1.2.2 Requirement Visual examination as in 2.1.2.1 shall allow identification, appearance, workmanship and finish of the item to be checked against the relevant specifica
17、tion. During visual examination, special care shall be taken to ensure that as a minimum requirement no cracking, significant discoloration, deformation and, where applicable, no ingress of water is in evidence.
