YY/T 0993-2015 in English

1 Scope

This standard specifies the method, specimen preparation, operation procedure and evaluation of in vitro cytotoxicity test for nanomaterials and those integrated in medical devices.

This standard is applicable to the evaluation on in vitro cytotoxicity of nanomaterials and those integrated in medical devices (except that particles or fiber is enveloped or combined to be unreleasable or non-free), including MTT assay and LDH assay which take L929 as the tested cell. This standard is a supplement to GB/T 16886.5.
