This standard specifies requirements and test methods for the physical properties of manual toothbrushes in order to promote the safety of these products for their intended use. It does not apply to manual interdental brushes and powered oral hygiene devices, as these instruments are covered by separate International Standards. This standard is a product standard. This second edition of the standard now also contains a test for handle impact resistance (according to the Izod pendulum impact test) and deals in particular with aspects of quality and product safety. This standard shall be used in conjunction with DIN EN ISO 22254. The committee responsible for this standard is NA 014-00-19 AA "Mundpflegeprodukte" ("Oral hygiene products") at NADENT at DIN.
