BS EN 61003-1:2016 – TC:2020 Edition

IEC 61003-1:2016 is applicable to pneumatic and electric industrial-process instruments or control device using measured values that are continuous signals either a mechanical (position, force, etc.) or a standard electric signal. It is intended to specify uniform terminologies and testing methods for performance evaluation of industrial-process instruments or process control systems modules with analogue measured values and two- or multi-position outputs. This third edition cancels and replaces the second edition published in 2004. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: – use of the term ‘two-position output’ instead of ‘two-state instrument’ (see 3.2); – use of the term ‘differential gap’ instead of ‘switching differential’ (see 3.4); – use of ‘fast transient/burst immunity requirements’ instead of ‘power supply transient overvoltages’, and revision of the test method (see 6.2.10); – deletion of 6.2.12 ‘common mode interference’ and 6.2.13 ‘normal mode interference (series mode) ‘tests of the previous edition; – use of the term ‘electromagnetic field’ instead of ‘radiated electromagnetic interference’, the test method remained the same (see 6.2.16); – use of the term ‘dielectric strength’ instead of ‘isolation test’, and revision of the reference (see 6.3.4); – deletion of Subclauses ‘8.2 Design features’, ‘10.1 Routine maintenance and adjustment’ and ‘10.2 Repair’ of the previous edition.
