1 Scope
This standard specifies the test method of soluble fluoride of dental materials. The soluble fluoride in this standard includes fluoride released by materials directly dissolving in water and fluoride dissolved in water after different treatment methods on the materials.
This standard is applicable to determination of soluble fluoride content in materials for dental repair, adhesion and prevention and healthcare.
