BS EN 61143-2 is an international standard that discusses the test methods of X-t recorders. BS EN 61143-2 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 61143-2 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 61143-2 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 61143-2 applies only to the recorder and does not apply to the control circuit.
Note 1: BS EN 61143-2 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 61143-2 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 61143-2 does not contain requirements concerning the dimensions of instruments or accessories (for the former, see IEC 473).
BS EN 61143-2 on test methods for X-t recorders is relevant to:
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 61143-2 gives details of tests that are specific to X-t recorders. BS EN 61143-2 provides users with an intrinsic error test that contributes to the performance characteristics of X-t recorders ensuring their reliability. BS EN 61143-2 provides a test of dynamic performance and value of the dead band helping users produce a high-quality product.
Overall, BS EN 61143-2 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.
