Access to Technical Documents

From this page, you can get access to the full text of ISO’s Fire Suppression Rating Schedule (FSRS) and detailed commentaries on selected sections of the FSRS.

The commentaries give technical details of the procedures and standards ISO uses in evaluating communities' fire-suppression systems. The information will give you further insight into how ISO develops the Public Protection Classification (PPCTM) for a community.

To get the most out of the commentaries, you should be familiar with the criteria in the FSRS. Look for links to the commentaries at the relevant places in the FSRS.
