Bibliography

Describes a method for the determination of allowable limits for substances leachable from medical devices. Determines use in deriving standards and estimating appropriate limits where standards do not exist. Also specifies a systematic process through which identified risks arising from toxicologically hazardous substances present in medical devices can be quantified.
