What is BS EN 61003-2 – Industrial process control systems about?
BS EN 61003-2 is the second part of the IEC 61003 multi-series that discusses industrial process systems. BS EN 61003-2 gives guidelines for inspection and routine testing of electrical and pneumatic instruments with two- or multi-position output, for instance, for acceptance tests or after repair, and it is to be used in conjunction with BS EN 61003-1:2016, BS EN 61298-2:2008, and BS EN 61298-3:2008.
BS EN 61003-2 is applicable to electrical and pneumatic industrial-process instruments, using measured values that are continuous signals. The setpoint value may be either a mechanical (position, force, etc.) or a standard signal. These instruments may be used as controllers or as switches for alarms and other similar purposes.
Quantitative criteria for acceptable performance should be established by agreement between manufacturer and user, and the report on the tests clarifies which tests were carried out. The requirements of BS EN 61003-2 are effective when agreed upon by the manufacturer and the user.
Who is BS EN 61003-2 – Industrial process control systems for?
BS EN 61003-2 on guidance for inspection and routine testing of electrical and pneumatic instruments is useful for:
- Developers of industrial process control systems
- Manufacturers of electrical and pneumatic instruments
- Testing laboratories
Why should you use BS EN 61003-2 – Industrial process control systems?
Pneumatic industrial process instruments regulate and monitor air pressure produced by the process or the machinery. If these instruments carry out their procedure inaccurately it can affect the process quality and also the lifecycle of the machinery.
BS EN 61003-2 guides you through the routine inspection and testing process necessary for the maintenance of pneumatic instruments. BS EN 61003-2 guidelines help you identify inaccuracies in the system, dielectric strengths, variations in supply voltage and supply pressure etc.
Overall, the guidance on BS EN 61003-2 enables you to keep your electric and pneumatic industrial instruments in optimum condition.
What’s changed since the last update?
BS EN 61003-2:2016 supersedes BS EN 61003-2:2009. BS EN 61003-2:2016 includes the following significant technical changes with respect to BS EN 61003-2:2009:
- Use of the term “two- or multi-position output” instead of “two- or multi-state instrument” (see scope)
- Use of the term “differential gap” instead of “switching differential” (see Table 1 No 2)
- Use of the term “dielectric strength” instead of “isolation test” (see Table 1 No 5)
