There's now a line of sprinklers listed for pressures up to 250 psi and they are the quick response types. Test results were favorable. This does not affect current designs, but should have a future impact on the standards. They are still collecting input so a proposed structure has not been developed. The NFPA is developing a glossary of terms.
Many words have multiple definitions from the different standards which are sometimes contradictory.
This is a good move toward standardization and reduction of confusion. This is currently sent out every two months as part of Fire News and called NFPA Standards Action . I received a phone call from a member about the information on corridors in the last issue of Tech Talk. The corridor is considered a unique situation, predominantly due to a very light fuel load, whereby the normal design approach is modified. When the corridor is the area under consideration adjacent rooms are NOT meant to be included in the design area.
