The China Household Electrical Appliances Association on April 18 released association standards called “Safe service life for household electrical appliances Part 7: Household drinking water purifier”, which came into effect immediately. The standards cover the terminology, requirements, normal use conditions, notes and labeling of the designed standard service life of water purifiers and set this service life to eight years.
When home appliances are used for many years, their condition deteriorates and it results in a higher risk of serious accidents. To address this issue, the China Household Electrical Appliances Association started to develop the “Safe service life for household electrical appliances” association standards and released in January 2020 standards for the service lives of refrigerators, wine cabinets, air conditioners, washing machines and dryers, range hoods, gas stoves and electric water heaters. The latest standards for water purifiers are the first addition to them since then.
The standards apply to household water purifiers with a single-phase rated voltage of 250 V or less.
Requirements on the designed standard service life of water purifiers
- Manufacturers should set out the designed standard service life of water purifiers they produce.
- The designed standard service life should be continuously counted from the product’s purchase date.
- Manufacturers should have statistics on safety failures of water purifiers they sell and data that can be used for traceability purposes, such as analytic data. Appendix A to the standards can be referred to for safety failure examples and for cause analysis.
- The designed standard service life of a water purifier is eight years.
- However, if a water purifier is installed, repaired or maintained by a person who is not designated by its manufacturer, the designed standard service life of the product ends when that operation is done.
Labeling of the service life
The label of the designed standard service life should be put on a conspicuous part of a water purifier’s main body or on its nameplate. The label should state the service life and the safety risks in the case of using the product beyond the service life.
There are two styles of labels as shown below. Labels of both styles can be enlarged or shrunk as needed.
The style 1 label of the designed standard service life of a water purifier
The style 2 label of the designed standard service life of a water purifier
