Caution regarding fire incidents caused by products using lithium-ion batteries. Are the standards tests and safety evaluations for electrical products sufficient?

Are you having trouble conducting the necessary standard tests for the sale of new products? We offer testing services for public standards applicable to household and commercial electrical products!

There are many standard tests that are recommended to verify products for sale. For example: - JIS standards (JIS C 60335-1 Safety of household electrical appliances, etc.) - IEC standards (IEC 61960 Batteries for portable devices, etc.) - UL standards (UL 1642 Lithium batteries, etc.) and so on. We undertake public standards applicable to household and commercial electrical products. ■ Do you have any of these concerns? ■ - I want to conduct standard tests on developed or purchased products, but I do not own testing equipment. - A business partner has requested the implementation of standard tests, but I have no experience. - I cannot determine whether the test results from the supplier are appropriate.

Prevent smoke and fire accidents and short lifespan in advance! We offer safety evaluations for secondary batteries, power supplies, AC adapters, noise tolerance assessments, and characteristic evaluations.

Accidents involving products equipped with lithium-ion batteries, such as mobile batteries, are increasing year by year. There are calls for caution regarding the rise in fire incidents caused by lithium-ion batteries due to high temperatures. Lithium-ion batteries are composed of flammable materials and inherently carry the risk of smoke and fire. As secondary batteries have rapidly proliferated, fire incidents have also been on the rise each year. This is not only due to the harshening of usage environments and mechanisms but also because the risks of smoke and fire have not been fully verified. As a third-party verification of battery units, we assess battery performance through tests different from PSE testing: - Nail penetration test (simulating internal short circuits to assess performance) - Heating limit test (heating to thermal limits to assess performance) - 0V charging prohibition protection (assuming recharging after long-term storage) Do you have any of these concerns? - I recognize that it is dangerous, but I don't know what to do. - I lack experience and know-how in evaluation, and I am anxious about ensuring safety. - I want to determine not only safety but also whether the battery has characteristics suitable for the product. - I want to evaluate the product's durability against high temperatures, drops, and impacts to prevent fire incidents in the market.

■Safety Evaluation, Lifespan Testing, and Characteristic Evaluation of Battery Units Lithium-ion batteries are composed of flammable materials and inherently carry the risk of smoke and fire. With the rapid proliferation of secondary batteries, fire incidents have been increasing year by year. This is partly due to the insufficient verification of smoke and fire risks. - Not all batteries are subject to PSE (Product Safety Electrical) regulations. - PSE certification tests do not fully verify safety. - Necessary protections may not be included. As a third-party verification of battery units, we assess the battery's capabilities through tests different from PSE testing: - Nail penetration test (simulating internal short circuit to assess capabilities) - Heating limit test (heating to thermal limits to assess capabilities) - 0V charging prohibition protection (assuming recharging after long-term storage) ■Power Supply Unit and AC Adapter Evaluation / Failure Analysis - Safety evaluation of power circuits, wireless power transmission, and USB PD (Power Delivery). - Conducting various noise injection tests to verify noise tolerance and characteristic evaluation in line with power supply specifications. - Evaluation of power supply devices such as power supply units, AC adapters, UPS, and DC-DC converters, including evaluation of the built-in power circuits and verification of power failures.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

Our company sells PDCE devices and the supports and fittings for installing these devices in various locations. The new lightning rod "PDCE Lightning Ball" is designed to "avoid" lightning strikes by incorporating features that make it difficult for lightning to approach, unlike traditional lightning rods. Its round shape and double structure with an insulator help suppress "welcoming discharge," which attracts lightning current. This lightning protection system complies with the lightning reception requirements of the "Building Standards Act." Rakurai Yokusei Systems Co., Ltd. https://www.rakurai-yokusei.jp/

We have launched a "Display Item Search Page" that allows you to search for unit houses currently on display at exhibition halls nationwide, which was made available on January 6, 2026. There are over 800 items listed on the website. You can filter by area, price range, size, purpose, product type, color, and more. You can also check exterior and interior photos, prices, facilities, and drawings/specifications online. If you're interested in a display item, you can directly inquire, make a reservation to visit, or consult via LINE. This is a convenient service that allows you to efficiently progress from comparison to detailed consideration. Please take a look!
