[Radio King] From October 7 for 4 weeks, Thursdays from 17:50 to 17:54 We will discuss the necessity of stop boards and the background of their development.

The design registration for the simple type water stop board Flood Guard F FZ80 has been completed.

We conducted a leakage test on 3 products. ≪Test Subjects≫ Flood Guard F: 2 units of FZ50, 1 unit of FT50, 1 unit of FG50, 1 unit of FGL50 Flood Guard Asia Specification: 3 units of DZ50, 2 units of SG50 Sandbags: 26 units ~Comparison Test Procedure~ Flooding Amount Fill fresh water to a level of 51 cm and adjust to maintain that water level. After visually confirming the stability of the water level, hold it for more than 1 minute. Then, after the leakage amount stabilizes, collect leakage from the drainage outlet for 1 minute. Perform the collection for 1 minute three times, calculate the average leakage amount from the mass of collected leakage, and convert it to an hourly rate to determine the leakage amount. *In accordance with the testing procedure of JIS 4716 Installation and Removal Time The time taken to complete the installation from the designated position to the installation position, and the time taken to return from the installation position to the designated position after drainage.

We conducted a leak test for Flood Guard F in our company's test pool. <<Test Subjects>> - 2 units of FZ50 - 1 unit of FT50 - 1 unit of FG50 - 1 unit of FGL50 ~Test Procedure~ Fill with fresh water up to a water level of 51 cm and adjust to maintain that level. After visually confirming the stability of the water level, hold it for more than one minute. Then, after the leak amount stabilizes, collect the leak water from the drainage outlet for one minute. Perform the collection for one minute three times, calculate the average leak amount from the mass of the collected leak water, and convert it to an hourly rate to determine the leak amount. *Although JIS standards do not apply to simple stop plates, we follow the JIS 4716-10 test procedure to maintain consistency and fairness in testing. However, unnecessary operations for the simple stop plates (such as measuring operating force using push-pull gauges, torque wrenches, etc.) will be omitted.

We have uploaded examples of the use of FG, FS, FT, and fitting bars, which are features of Flood Guar F.

In the fall of 2021, we plan to sell the Flood Guard F F65 and F80. The F65 has a waterproof height that is 15 cm higher than the F50, and the F80 has a waterproof height that is 30 cm higher than the F50. These items are very effective in mitigating more severe flood damage and storm surge damage.

"Flood Guard F" is a simplified water stop board that has been certified by clearing the evaluation criteria for disaster prevention necessity, safety, and functionality at the 23rd Disaster Prevention Product Recommendation Review Committee of the General Incorporated Association for Disaster Prevention and Safety. We conducted a leakage test using this product and the "Flood Guard Asia Specification." Fresh water was stored up to a water level of 51 cm, and adjustments were made to ensure that the water level did not fall below this point. After visually confirming the stability of the water level for more than one minute, we collected leakage from the collection point for one minute after the leakage amount stabilized. This collection was done three times, and the average leakage amount was calculated from the mass of the collected leakage, which was then converted to an hourly leakage rate. Our company is committed to daily research and development to provide better products. [Test Subjects] ■Flood Guard F: 2 units of FZ50, 1 unit of FT50, 1 unit of FG50, 1 unit of FGL50 ■Flood Guard Asia Specification: 3 units of DZ50, 2 units of SG50 ■Sandbags: 26 units

The "Flood Guard F" has been certified by the General Incorporated Association for Disaster Prevention and Safety as a product that can be beneficially utilized in the field of disaster prevention, contributing to safety, functionality, and convenience.

Our company will be exhibiting at the 15th Office Disaster Prevention EXPO, which will be held at Tokyo Big Sight from April 7 (Wednesday) to April 9 (Friday), 2021. On that day, we will announce the new flood barrier "Flood Guard F" and showcase "FZ50," "FN50," and "FW50." We sincerely look forward to your visit.
