What is BS EN 61143-1 - Definitions and requirements of X-t recorders?
BS EN 61143-1 is an international standard that discusses the definitions and requirements of electrical measuring instruments.
BS EN 61143-1 applies to X-t recorders used for the measurement of voltage and current which measures and records analogue electrical quantities as a function of time. BS EN 61143-1 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 51 also apply.
BS EN 61143-1 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, BS EN 61143-1 applies only to the recorder and does not apply to the control circuit.
Note 1: BS EN 61143-1 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.
Note 2: BS EN 61143-1 does not cover safety requirements (for reference, see IEC 1010) and does not contain either requirement for protection against environmental conditions or the relevant tests. However, when necessary, tests under conditions approach those of use are selected from IEC 68, to prove protection against environmental conditions.
Note 3: BS EN 61143-1 does not contain requirements concerning the dimensions of instruments or accessories (for the former, see IEC 473).
Who is BS EN 61143-1 - Definitions and requirements of X-t recorders for?
BS EN 61143-1 on definitions and requirements of X-t recorders is relevant to:
- Manufacturers of X-t recorders
- Manufacturers of electrical measuring instruments
- Electrical engineers
- Electricians
- Testing authorities
- Regulatory authorities
Why should you use BS EN 61143-1 - Definitions and requirements of X-t recorders?
X-t recorder is an instrument that records on a recording medium information corresponding to the values of the measurand. An electrical measuring instrument is a measuring instrument that intends to measure an electrical or non-electrical quantity using electrical means.
BS EN 61143-1 provides the characteristic features of recorders and assists with the influence quantities, reference conditions, nominal range of use, and preconditioning of recorders. BS EN 61143-1 describes recorders and their non-interchangeable accessories according to their principle of operation. BS EN 61143-1 classifies recorders and their non-interchangeable accessories according to their accuracy classes related to the measurand and to timekeeping. BS EN 61143-1 also assists with the reference conditions for the X-t recorder and its intrinsic errors. BS EN 61143-1 provides users with various tests, like, vibration test, and shock test that contributes to the performance characteristics of X-t recorders ensuring their reliability. BS EN BS EN 61143-1 aid the markings and symbols for terminals.
Overall, BS EN 61143-1 is useful as it provides guidance on electrical measuring instruments that can be beneficial for your business and can also help you to expand your business globally.
