Standards for control systems make ensuring that process industries are safe, consistent, and efficient. These standards, which range from ISA-5.1 for instrumentation symbols to IEC 61511 for functional safety, help design, build, and keep control systems running in industries including oil and gas, chemicals, and power. This quiz has 25 tough questions that test your advanced understanding of international standards including ANSI, ISA, and IEC. This quiz is great for control engineers, DCS/PLC experts, and EPC engineers because it helps you learn more about safety rules, industrial standards, and best practices. Let’s see how well you know the basics of current automation!
