Scope

YY/T 0606.8-2008 is the English-translated version of 组织工程医疗产品 第8部分:海藻酸钠.

YY/T 0606.8-2008 belongs to the Chinese tissue-engineered medical products series and deals with sodium alginate as a starting material. It covers alginate used to make tissue-engineered medical products and surgical implants.

Characterisation draws on ASTM F2064 for alginates in biomedical applications and on ASTM F2259 for determining chemical composition and monomer sequence by 1H-NMR, alongside the USP monograph for alginate.

Biocompatibility is judged through the GB/T 16886 tests, among them cytotoxicity, interaction with blood, implantation, irritation, sensitisation and systemic toxicity, while lot acceptance uses the AQL sampling plans of GB/T 2828.1.

It also defines degradation, meaning structural change caused by environmental, chemical or thermal factors. Issued on 25 April 2008, it has applied since 1 June 2009.
