Specification for Thermal Spray Feedstock Solid and Composite Wire and Ceramic Rods

IEC 62246-1:2002 簧片触点.第1部分:总规范

This part of IEC 62246 which is the generic specification applies to dry and mercury wetted reed contact units of assessed quality. It lists the tests and measurement procedures which may be selected for use in detail specifications for such units. This standard also specifies the quality assessment procedures to be followed. This standard applies to those reed contact units which are operated by an applied magnetic field; it is not restricted to any particular type of contact load. NOTE 1 Since tests using a standard coil and standard resistive loads are the easiest to specify and to define, this standard is currently restricted to tests of this type. NOTE 2 For elementary relays with reed contact units, this standard is recommended to be used together with the standards IEC 61810-1 and IEC 61811-1 as applicable. Where in this part of IEC 62246 the term "detail specification" is used, this either has the meaning defined in A.7 of QC 001001 for application within the IECQ system, or it means any appropriate document, for example manufacturer's data sheet, test specification, customer detail specification.

At the end of their maintenance cycle, it is recommended to revise published documents where applicable using these preferred terms. For easy use, the terms are given in alphabetical order, with the title, description and additional information about the source, status and recommendations: · Description: where applicable, a note is added to clarify. · Source: the publication or project in which the term has been used. · Status: the following status types (in alphabetical order) have been used: Deprecated an IEV term, which has been replaced by a better term. Draft the term forms part of a document, which is currently in preparation. Modified the listed term deviates from a published term. Obsolete the published term is no longer in use. Published the term has been published in an IEC document. Superseded the term has been superseded by another published term. Unique fully new term that has not been used in any document. · Apply: recommendation to the author of a new or a revised standard.
