The w
12、ork 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 organizations, governmental and non-govern
13、mental, 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.The procedures used to develop this document and those intended for its further maintenance are described in t
14、he 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 drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the poss
15、ibility 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. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list o

20、g single standards on each type of glow-plugs.It is intended to specify the main properties, the design requirements, and the dimensions of most of the existing types of glow-plugs and their cylinder head housings. It is to enable the user to work with one comprehensive document valid for most types
21、 of glow-plugs instead of a number of standards, each of them specified for one type only.ISO 17447-1 covers basic characteristics and dimensions for metal-sheath-type glow-plugs. ISO 17447-2 covers basic characteristics and dimensions for ceramic-sheath-type glow-plugs. Tests and requirements are d
22、efined in this part of ISO 17447.It is intended to withdraw the following standards on glow-plugs and their cylinder head housing as soon as this part of ISO 17447 is published:ISO 6550-1, ISO 6550-2, ISO 6550-3, ISO 6550-4, ISO 7578.

23、015Road Vehicles Glow-plugs with conical seating and their cylinder head housing Part 3: Tests and requirements1 ScopeThis part of ISO 17447 specifies general requirements and test methods for sheath-type glow-plugs. Detailed test condition(s) and/or requirement(s) are agreed between the glow-plug m
24、anufacturers and the engine manufacturer. It is applicable to glow-plugs conforming to ISO 17447-1 and ISO 17447-2, used in diesel (compression ignition) engines.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for
25、its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.IEC 60068-2-6, Environmental testing Part 2-6: Tests Test Fc: Vibration (sinusoidal)3 Terms and definitionsFor the purpose o
