In terms of application, which of the following is NOT included under the standard for sprinkler systems?

The application of standards for sprinkler systems primarily focuses on the technical and functional aspects crucial for ensuring the effectiveness and reliability of fire protection systems. In this context, the character and adequacy of water supplies pertain directly to how well the system can perform during an emergency, ensuring there is sufficient water pressure and volume available for efficient fire suppression.

Selection of fittings is essential because it affects the integrity and operation of the sprinkler system, ensuring all components work together seamlessly to deliver water effectively throughout the area needing protection. The installation of valves and piping is also critical as it directly influences how the system is assembled and operates; proper installation ensures that the system is functional and compliant with safety standards.

In contrast, marketing and promotion of sprinkler systems fall outside the scope of technical standards and application. This aspect relates more to business practices and strategies for selling sprinkler systems rather than the design, installation, or operational guidelines necessary for their effectiveness in fire protection. Consequently, it is not included under the standard for sprinkler systems, which focuses on safety, performance, and compliance rather than commercial interests.
