IEC 61143-1:1998 PDF

Scope: This part of IEC 61143 applies to X-t recorders used for the measurement of voltage and current which measure and record analogue electrical quantities as a function of time. It also applies to a recorder whose chart scale lines do not correspond directly to the electrical input quantity, provided that the relationship between them is known. For the measurement of other electrical quantities, the relevant parts of IEC 60051 also apply. This part also applies to non-interchangeable accessories and accessories of limited interchangeability (e.g. shunts, impedance elements) if they are used with the recorder and the adjustments have been made for the combination. For controllers with electrical outputs and containing electrical recorders, this part applies only to the recorder and does not apply to the control circuit. This part does not apply to special purpose recorders or to special purpose devices (when they are used as accessories) which are covered by their own IEC standards. This part does not cover safety requirements (for reference, see IEC 61010) and does not contain either requirements for protection against environmental conditions or the relevant tests. However, when necessary, tests under conditions approaching those of use may be selected from IEC 60068, to prove protection against environmental conditions. Further, it does not contain requirements concerning the dimensions of instruments or accessories (for the former, see IEC 60473).
