Which of the following is NOT part of the minimum requirements identified in the sprinkler standard?

The minimum requirements identified in the sprinkler standard focus primarily on aspects that directly impact the safety, effectiveness, and reliability of sprinkler systems. These include the selection of fittings, design and installation protocols, and testing requirements, all of which are crucial for ensuring that the systems function properly and meet safety regulations.

The selection of fittings is essential to ensure compatibility and functionality within the fire protection system. Design and installation protocols provide guidance on how to effectively implement these systems in various settings, adhering to best practices and safety codes. Testing requirements are also critical as they ensure that the installed systems perform as intended, which is key to protecting lives and property.

On the other hand, writing and distributing promotional materials is not typically considered a part of these essential requirements. This activity may be relevant to marketing or communication efforts but does not directly influence the technical specifications or operational integrity of sprinkler systems as laid out in the standards. Therefore, this is why this choice stands apart from the core requirements defined by the sprinkler standards.
