NAMUR is an important concept in the field of automation and process control, areas that are closely related to your expertise in electrical, electronics, instrumentation, and control systems.

What is NAMUR?

  1. Origin and Definition: NAMUR is an acronym for “Normenarbeitsgemeinschaft für Mess- und Regeltechnik in der Chemischen Industrie”, which translates to “Standardization Committee for Measuring and Control in the Chemical Industry”. It is an international association of automation technology users in the process industries, primarily chemical and pharmaceutical companies.
  2. Purpose: The primary aim of NAMUR is to promote the development and use of automation technologies through the creation of recommendations and worksheets. These documents are used as guidelines or standards to ensure consistency, interoperability, and safety in automation systems.


  1. NAMUR Devices: Devices that comply with NAMUR standards are designed to meet specific requirements for use in process control and automation, particularly in hazardous environments. These standards cover aspects like signal levels, fault tolerance, and safety measures.
  2. Non-NAMUR Devices: Non-NAMUR devices are those that do not conform to the NAMUR standards. While they may be used in various industrial applications, they might not be suitable for specific environments or applications that require adherence to NAMUR guidelines.

Why Was NAMUR Introduced?

  1. Standardization and Safety: The chemical and pharmaceutical industries often deal with hazardous materials and processes. NAMUR standards were introduced to ensure a high level of safety and reliability in automation systems used in these industries.
  2. Interoperability and Compatibility: With diverse equipment and systems used in industrial processes, NAMUR standards help in ensuring compatibility and interoperability among different devices and systems, facilitating smoother and safer operations.
  3. Innovation and Development: By providing a common set of guidelines, NAMUR encourages manufacturers to innovate and develop new technologies that comply with these standards, thus advancing the field of process control and automation.
  4. Global Acceptance: As industries become increasingly globalized, having a set of widely recognized and accepted standards is crucial for international operations and collaborations.
