Bibliography

ISO 11143:2008 specifies requirements and test methods for amalgam separators used in connection with dental equipment in the dental treatment centre. It specifies the efficiency of the amalgam separators in terms of the level of retention of amalgam based on a laboratory test and the test procedure for determining this efficiency. It also includes requirements for the safe functioning of the amalgam separator, for marking, instructions for use, operation and maintenance.All tests described in ISO 11143:2008 are type tests.
