Perfluoro(2-methyl-3-pentanone) is a fluorinated ketone with the structural formula CF 3 CF 2 C(=O)CF(CF 3) 2, a fully-fluorinated analog of ethyl isopropyl ketone.It is used as an electronics coolant liquid and fire protection fluid sold commercially by 3M under brand names such as Novec 1230, Novec 649, and FK-5-1-12.
n.o.s. = not otherwise specified meaning a collective entry to which substances, mixtures, solutions or articles may be assigned if a) they are not mentioned by name in 3.2 Dangerous Goods List AND b) they exhibit chemical, physical and/or dangerous properties corresponding to the Class, classification code, packing group and the name and description of the n.o.s. entry [4]
For instance, there is no such thing as a Novec 1230 System. There are systems that use Novec 1230 fluid. There are also systems that use the numerals 1230 to describe the system. However, the fluid can only be referred to as Novec 1230, when referenced the commercial name or by its chemical name or Ashrae description used in NFPA 2001 as FK-5 ...
Its fully fluorinated analog is known as Novec 1230 and is used in gaseous fire suppression. References. a b This page was last edited on 18 July 2024 ...
The compound has been introduced into the market by 3M under the denomination Novec 4710 [4] and commercialized in high voltage equipment by General Electric starting from 2016. [5] It is seen as a credible alternative to SF 6 by the European Commission as offering the capability to replace SF 6 while keeping the same benefits of dimensional ...
Charge carrier density, also known as carrier concentration, denotes the number of charge carriers per volume. In SI units, it is measured in m −3. As with any density, in principle it can depend on position. However, usually carrier concentration is given as a single number, and represents the average carrier density over the whole material.

Systems working on a total flooding principle apply an extinguishing agent to a room in order to achieve a concentration of the agent (volume percent of the agent in air) adequate to extinguish the fire. These types of systems may be operated automatically by detection and related controls or manually by the operation of a system actuator.
