What is ISO 23325 about?
ISO 23325 discusses corrosion resistance of dental amalgam for dentistry. ISO 23325 outlines requirements for the permissible reduction in strength resulting from crevice corrosion of dental amalgam products that are within the scope of ISO 24234 or ISO 20749.
ISO 23325 provides details of the test procedure for determining corrosion resistance in dental amalgam.
Note: Specific qualitative and quantitative requirements for freedom from biological hazards are not included in ISO 23325.
Who is ISO 23325 for?
ISO 23325 on corrosion resistance of dental amalgam is useful for:
- Manufacturers of dental amalgam
- Dentists
- Test centres for dentistry
- Regulatory authorities
Why should you use ISO 23325?
Dental amalgam alloy is in fine particles, composed mainly of silver, tin, and copper. When mixed with dental mercury, produces a dental amalgam for dental restoration. Dental mercury is supplied for use in the preparation of dental amalgam.
ISO 23325 guideline provides information on sampling, requirements, preparation of the dental amalgam test-piece, test solution (artificial saliva), procedure for test-piece conditioning, and mechanical testing for corrosion resistance of dental amalgam. This helps accelerate the effect, such that results are obtained in a time suited to an in vitro test.
