The rules for dimensioning are established by the American National Standards Institute (ANSI). According to ANSI, dimensions can be in inches (U.S. customary) or in metric or dual dimensions that list both U.S. customary and metric. Dimensions can either be positioned on an engineering drawing as unidirectional or aligned (see Figure 6-18). 

The P ID plays a vital role in maintaining processes as described. All instrumentation should be reviewed periodically to ensure the functionality of the control and the safety of the systems. Therefore, drawings must be clear and understandable. In such drawings like the PFD, it is preferable to follow the relevant international standards. The most widely used standard is the ANSI/ISA of the... 

Subjects for criticality safety standards may arise from any source in which a sufficient need is identified. In the past, topics for consideration have been suggested by members of ANS-8, ansi Subcommittee N16, the ANS Standards Steering Committee, criticality safety specialists, and others. To accomplish preparation of draft standards, ANS-8 utilizes work groups led by interested and dedicated group leaders. Because of direct sponsorship and support by the Nuclear Criticality Safety Division of ANS, a broad base of national and intemation criticality safety expertise is available to draw upon in accomplishing assigned tasks and developing consensus on each project... 

ANSI/USAS Y32.10-1967 drawing symbols should be used. The electrical designation and descriptions on related pneumatic/hydraulic piping diagrams shall match those on the electrical diagrams. 

The mathematical model of the mechanical actuator system can be developed directly from the CAD design drawing by means of commercial FEM software tools, e.g. ANSYS [3]. This model is fundamental for the calcula-tional modal analysis which serves to find out the systems natural frequencies. Figure 6.10 shows the FEM model of the active piezo absorber and gives an impression of the third vibration mode of the structure which is used in this example for the vibration absorption. 

BPCS have been shown through communication bus. Here, it is interesting to note that there could be separate BPCS and SIS, but these two could be integrated as long as they meet the requirements of standards like lEC 61508/61511 or ANSI/ISA 84. In view of the same in the drawing BPCS has been shown in dotted meaning that integration is possible.

Use tools required for system layout and design, such as (1) system layout VPE, PDMS CATIA etc (2) core prediction codes, eg, SCALE (3) core and system thermohydraulic codes like ANSYS-CFX, RELAP, and CATHARE etc (4) drawing tools like AutoCAD, CATIA, Corel Designer and (5) documentation tools.

The ANSI has published standard line and lettering practices for use in the preparation of engineering drawings (20). The standard describes the size, construction, and appropriate use of various types of lines for engineering drawings. Figure 6.5 shows the various t5 es of lines and how they are drawn and used.
