FAQ

Q: What are the most critical tests for a ceramic toilet or basin?

A: The most critical are Radial Breaking Strength (structural load capacity), Glaze Acid/Alkali Resistance (stain and chemical durability), and Water Absorption (porosity control). Manufacturers like Dongguan Lituo provide dedicated, certified equipment for all these tests.

Q: Why is salt spray testing so important for bathroom faucets?
A: Bathrooms are humid environments, and water often contains chlorides. Salt spray testing (a specialty of GTG Testing) is an accelerated corrosion test that predicts how a faucet’s finish and internal components will withstand years of exposure, preventing cosmetic and functional failures.

Q: We manufacture smart toilets. What specialized testing do we need beyond hydraulic tests?
A: You require Electrical Safety Testing (dielectric strength, leakage current), Functional Endurance Testing of sensors, actuators, and heaters, and IP Code Rating Tests for water ingress protection. Wuxi Zhongke Instrument specializes in this mechatronic testing nexus, while Dongguan Lituo can provide integrated solutions covering both hydraulic and basic electronic validation.
