What does the vertical rule (|) symbolize in the context of fire sprinkler system standards?

The vertical rule (|) is used in fire sprinkler system standards to indicate changes other than editorial. This is important in the context of standards because it allows readers and industry professionals to easily identify modifications that impact the content and application of the regulations or guidelines, ensuring they are aware of crucial updates that may affect design, installation, or inspection practices.

Understanding what constitutes a change beyond mere editorial adjustments is vital for compliance and maintaining the safety and effectiveness of fire suppression systems. These changes could include alterations in technical specifications, installation procedures, or safety requirements, which are significant for ensuring that systems are reliable and meet current codes and standards.

In contrast, other symbols or notations may have different meanings, such as indicating deletions, referencing materials from other documents, or pointing to explanatory materials, but in this case, the vertical rule specifically focuses on non-editorial changes.
