The Safety Instrumented Systems (SIS) and critical alarms assigned a Class 1 include those that have been mandated as such by state or federal agencies an in-house technical safety review committee HAZOP studies and specific alarms deemed critical by operations supervisors. All of these Safety Instrumented Systems and alarms are on a regular prooftesting schedule. 

Books have been written about each of these sub-topics and many standards exist to specify best practices or provide guidance. The Instrumentation, Systems and Automation Society (ISA) is the primary professional society that addresses many of these different aspects of process control. The focus of this chapter will be on control loop principles, loop tuning, and basic control strategies for continuous processes.

International standard symbols for instruments, controllers, and valves are given by the Instrumentation Systems and Automation Society design code ISA-5.1-1984 (R1992). Some companies use their own symbols though, and different standards are followed in some countries, such as BS 1646 in the UK and DIN 19227 and DIN 2429 in Germany (see references).

In the past 10 years there has been an increasing emphasis on the relationship of various lipids to atherosclerotic heart disease. The clinical laboratory is performing a greater number of lipid determinations as well as a larger variety of procedures. In order to meet these demands, laboratories are increasingly turning to automated instrumentation and methodology. This review will discuss one automated instrumental system, and the lipid techniques that have been adapted to it.
