BS EN ISO 23325:2020,Dentistry – Corrosion resistance of dental amalgam.
BS EN ISO 23325:2020 sets a requirement, being the acceptable limit, for the reduction in strength of dental amalgam that is a consequence of crevice corrosion when the test is conducted using the procedure specified in this document. It uses one of the three corrosion test procedures present in ISO/TS 17988 for which a requirement is given in this document. The testing protocol is designed to accelerate the effect, such that results are obtained in a time suited to an in vitro test. Its purpose is to differentiate acceptable products from those that are not (by using a benchmark value) and not to rank products. It is not intended for use in product comparison claims.
Specific qualitative and quantitative requirements for freedom from biological hazard are not included in this document, but it is recommended that reference be made to ISO 10993-1 and ISO 7405 for assessing possible biological hazards. The test procedure in this document is inappropriate for assessing possible biological hazards.
This document specifies the requirements for the permissible reduction in strength crevice corrosion of dental amalgam products that are within the scope of ISO 24234 or ISO 20749.It provides details of the test procedure for determining this.
