If you are designing a system using HFC-227ea, here is what you will reference in the PDF document.

For HFC-227ea, cardiac sensitization occurs at high levels. The NOAEL limit is 9.0% . Systems designed for occupied spaces should not exceed this concentration unless safe exposure time limits are strictly calculated. : Fire suppression calculations leave no room for error

(the latest active version) specifically covers the requirements for systems using HFC-227ea (heptafluoropropane), commonly known by trade names such as FM-200 or Novec 1230 (though Novec has its own separate standard under ISO 14520-12). HFC-227ea is a clean, colorless gas that extinguishes fires primarily through heat absorption (physical mechanism) rather than chemical interference with oxygen.
