Hydrogen bath machine certifications

CE marking indicates the product meets the electrical safety, EMC and other applicable directives required to be sold in the European Economic Area. For a bath machine this covers the AC-side power supply, internal isolation and product safety construction.

FCC certification covers electromagnetic interference characteristics for sale in the United States. A unit that passes FCC will not interfere with nearby radio equipment or be excessively susceptible to it.

RoHS restricts the use of lead, mercury, cadmium, hexavalent chromium and certain brominated flame retardants in electronic equipment. It is a materials specification, not a performance test.

ISO 9001 is the general quality-management standard — it audits how a manufacturer documents, controls and traces its production processes. ISO 13485 is the stricter variant used in medical-device manufacturing and applies the same disciplines at higher rigour. A bath machine manufactured under either standard has a documented production process and traceable parts.

Important: ISO 13485 manufacturing context does not register the device as a medical device. Bath One™ and WZ-1™ remain general wellness products.

In a category where most listings are unbranded, certifications are the most reliable hardware-quality filter a buyer has. They do not describe outcomes — they describe whether the device was built and tested to a recognised standard.
