3 Foreword All technical content of this Part of GB is mandatory. GB consists of the following 5 parts, under the general title Sterilization of health care products - Biological indicators: - Part 1: General requirements; - Part 2: Biological indicators for ethylene oxide sterilization processes; - Part 3: Biological indicators for moist heat sterilization processes; - Part 4: Biological indicators for dry heat sterilization processes; - Part 5: Biological indicators for low-temperature steam and formaldehyde sterilization processes. This Part is Part 1 of GB This Part is drafted in accordance with the rules given in GB/T This Part replaces GB Sterilization of health care products - Biological indicators - Part 1: General requirements. Compared with GB , main technical changes in this Part are as follows: - ADD the specific information of self-contained biological indicators; - ADD figures and tables of the general requirements for labellling; - ADD the requirements for specific minimum biomass and/or resistance standard scope in the use of biological indicators, those scope are detailed indicated in product labelling; - SPECIFY in Annex D that it can use HSKP, LHSKP and SMCP procedures to calculate D value. This Part uses translation method to identically adopt ISO :2006 Sterilization of health care products - Biological indicators - Part 1: General requirements. Corresponding Chinese documents of the international document in the normative reference of this Part are as follows: - GB/T Data elements and interchange formats - Information interchange - Representation of dates and times (ISO 8601:2000, IDT); - Sterilization of health care products - Biological indicators - Page 3 of 54

5 Sterilization of health care products - Biological indicators - Part 1: General requirements 1 Scope 1.1 General This Part of GB provides general requirements for production, labelling, test methods and performance characteristics of biological indicators, including inoculated carriers and suspensions, and their components, to be used in the validation and routine monitoring of sterilization processes This Part specifies basic and common requirements that are applicable to all subsequent parts of GB Requirements for biological indicators for particular specified processes are provided in the subsequent parts of GB If no specific subsequent part is provided, this Part applies. 1.2 Exclusions This Part does not apply to microbiological test systems for processes that rely on physical removal of microorganisms, e.g. filtration processes or processes that combine physical and/or mechanical removal with microbiological inactivation, such as use of washer disinfectors or flushing and steaming of pipelines. This Part, however, could contain elements relevant to such microbiological test systems. 2 Normative references The following referenced documents are indispensable for the application of this document.
