34、ssment 1 Scope This part of the IEC 62246 which is a quality assessment specification defines requirements and tests to reed switches for use in general and industrial applications. This standard is intended to be used in conjunction with IEC 62246-1:2011. This standard selects from IEC 62246-1:2011

35、 and from other sources the appropriate test procedures to be used in detail specifications derived from this specification. Reed switch types are specified depending on characteristic values and tests. NOTE Mercury wetted reed switches are not covered by this standard due to their possible environm
