Functional Analysis Technique function diagram

Fig. 3 Schematic diagram illustrating the essential aspects of the differential thermal analysis technique. The experimental observable is the differential temperature between sample and reference, which will be plotted as a function of the system temperature.

As with all types of system safety analysis techniques discussed in this part of the text (Part II), a complete description of the system, its intended purpose and design functions, as well as any operational flow diagrams must also be evaluated during the performance of an SCA. If the analyst is not entirely familiar with these system characteristics, the subsequent SCA will potential be inaccurate, incomplete, and flawed.

Many chemists, biochemists, and medicinal chemists devote much time in the laboratory gathering quantitative information about systems that are important and interesting to them. The central role of analytical chemistry in this enterprise and many others is illustrated in Figure 1-1. All branches of chemistry draw on the ideas and techniques of analytical chemistry. Analytical chemistry has a similar function with respect to the many other scientific fields listed in the diagram. Chemistry is often called the central science its top center position and the central position of analytical chemistry in the figure emphasize this importance. The interdisciplinary nature of chemical analysis makes it a vital tool in medical, industrial, government, and academic laboratories throughout the world. 

The causes of hazards and functional failures are broken down, e.g. via Fault Tree Analysis (FTA). Other typical techniques are the Failure Modes, Effects and Criticality Analysis (FMECA) and the production of a Reliability Availability Maintainability Modelling and Prediction Report (RAM MPR), containing reliability block diagrams of the system.
