These changes are also occurring in Korea, and recently, fires such as ESS (Energy Storage System) battery fires, metal fires (magnesium, aluminum, etc.), and large high-rise building fires are rapidly increasing.

In such a situation, research and development for new technologies and performance improvement of fire extinguishing devices, fire extinguishing facilities, and fire extinguishing agents are being actively conducted for rapid and efficient evolution. As for the double fire extinguishing agent, research on performance improvement through pretreatment of general fire extinguishing water (water) and various types of wetting agents and additives is continuously being conducted.

However, the current domestic technology level and related laws only present the standards for the physical properties of each fire extinguishing agent and the criteria for fire extinguishing performance evaluation by fire type as an extinguishing agent. For this reason, there is no standard that can represent the standard performance of the developed fire extinguishing agent, so its applicability in the field is falling. In addition, since quantitative data necessary for R&D cannot be secured, active R&D activities are not being performed.

Globally, fires are classified into general fires, oil fires, electric fires, metal fires, gas fires, etc. In Korea, general fires (Class A), oil fires (Class B), electric fires (Class C) and kitchen fires It is classified as fire (class K).

Therefore, there is a need to develop a device capable of quantitatively evaluating the extinguishing performance of each extinguishing water for various types of extinguishing water including self-extinguishing water, additives, and thickeners.
