GB/T 16886.14-2003 (Biological evaluation of medical devices -- Part 14: Identification and quantification of degradation products from ceramics) is available as an English-translated PDF.

GB/T 16886.14-2003 — This Part of GB/T 16886 specifies two methods of obtaining solutions of degradation products from ceramics (including glasses) for the purposes of quantification.

It also gives guidance on the analysis of these solutions in order to identify the degradation products. Because of the generalized nature of this Part of GB/T 16886, product specific standards, when available, that address degradation product formation under more relevant conditions of use, should be considered first.

This Part of GB/T 16886 considers only those degradation products generated by a chemical dissociation of ceramics during in vitro testing. No degradation induced by mechanical stress or external energy is covered.

It is noted that while ISO 6872 and ISO 9693 cover chemical degradation tests, they do not address the analysis of degradation products. Because of the range of ceramics used in medical devices and the different requirements for accuracy and precision of the results, no specific analytical techniques are identified.

Further, this Part of GB/T 16886 provides no specific requirements for acceptable levels of degradation products. Although these materials are intended for biomedical applications, the biological activity of these degradation products is not addressed in this Part of GB/T 16886.

Biological Evaluation of Medical Devices -

Part 14. Identification and Quantification

of Degradation Products from Ceramics

1 Scope

This Part of GB/T 16886 specifies two methods of obtaining solutions of degradation

products from ceramics (including glasses) for the purposes of quantification. It also

gives guidance on the analysis of these solutions in order to identify the degradation

products. Because of the generalized nature of this Part of GB/T 16886, product

specific standards, when available, that address degradation product formation under

more relevant conditions of use, should be considered first.

This Part of GB/T 16886 considers only those degradation products generated by a

chemical dissociation of ceramics during in vitro testing. No degradation induced by

mechanical stress or external energy is covered. It is noted that while ISO 6872 and

ISO 9693 cover chemical degradation tests, they do not address the analysis of

degradation products.

Because of the range of ceramics used in medical devices and the different

requirements for accuracy and precision of the results, no specific analytical

techniques are identified. Further, this Part of GB/T 16886 provides no specific

requirements for acceptable levels of degradation products.

Although these materials are intended for biomedical applications, the biological

activity of these degradation products is not addressed in this Part of GB/T 16886.
