Innovation starting with toilets
TOTO, a leading company in toilets and spray seat combines traditional craftsmanship with electrical and mechanical features to achieve diversified functions of a sanitaryware. To further breakthrough in the world market, TOTO’s global development and values go beyond design ability, functionality and product safety.
Offering our safe and secure WASHLET® to the world
Conforming with IEC 60335-1 and acquiring the certification have been challenging. TOTO’s goal of achieving high level of product safety makes the Protective Electronic Circuit (PEC) indispensable.
According to IEC 60335-1, design and evaluation based on functional safety in connection with the product introduction are required. However, there has been no case of development fully considering PEC and functional safety in products having the standard mentioned above. TOTO selected TÜV SÜD as a third-party certification authority and a partner to work on unprecedented development, and succeeded in creating new product from scratch. This was a pioneering instance in the world.
TOTO acquiring TÜV SÜD certification for their product not only provides a platform for expansion on the world stage but also highlight their conformity with global safety standards.
Creating safe and secure products accepted worldwide
Mr. Shinji Okano, a group leader of the WASHLET® Quality Assurance Division, said: “That is why conformity with IEC 60335-1 was a major premise.”
A spray seat is a product that requires extremely highsafety. The warm water that is heated to wash users’ bottom must safely wash them while keeping the temperature high enough for the user and low enough for safety.
TOTO enhances the Japanese toilet culture to the world through accelerated global development. Regarding product safety as one of the most important matter, TOTO has developed products compliant to the IEC 60335-1 safety standards of shipping destinations such as the USA, China and South Korea.
However, a third-party certification authority provided us with unexpected information in 2013, saying: “TOTO’s spray seat which uses instantaneous warm water may possibly fail to conform with IEC 60335-1 in the near future.”
