Test method of effectiveness of sterilization process for reusable medical devices1 ScopeThis standard specifies test methods of determining the effectiveness of sterilization process for reusable medical devices. This standard applies to tests that have established the effectiveness of the sterilization process, it does not apply to the validation of the sterilization process.2 Normative referencesThe following documents are essential to the application of this document. For the dated documents, only the versions with the dates indicated are applicable to this document; for the undated documents, only the latest version (including all the amendments) are applicable to this standard. GB/T 6682 Water for analytical laboratory use - Specification and test methods GB 18281.2 Sterilization of health care products―Biological indicators - Part 2. Biological indicators for ethylene oxide sterilization processes GB 18281.3 Sterilization of health care products - Biological indicators - Part 3. Biological indicators for moist heat sterilization processes GB 18281.4 Sterilization of health care products - Biological indicators - Part 4. Biological indicators for dry heat sterilization processes The Pharmacopoeia of the People’s Republic of China (2015 version), volume IV3 Terms and definitionsThe following terms and definitions apply to this document. 3.1 Bioburden The total number of microorganisms on or in a product and/or its package.4 Overview4.1 This standard determines the effectiveness of the sterilization process by analyzing the recovery control and the results of the process test cycle. The recovery control shall be greater than or equal to 106 CFU/piece. 4.2 Residual bacterial spores are recovered by flushing, wiping or rinsing by eluents. It may use mechanical shock, ultrasonic and repeated rinsing by eluent to improve the recovery rate. 4.3 After the sample has been processed through a complete sterilization process, it shall use a specific elution technique to recover all residual bacterial spores from the device. 4.4 Use a minimum 5 devices to perform a process test cycle, or otherwise use one device to perform at least 5 consecutive process test cycles. If they are all qualified, this sterilization process is valid. 4.5 The person conducting this standard testing shall have an educational background in microbiology or related professional knowledge. 4.6 The sterility inspection and microbial limit inspection shall comply with the corresponding requirements of the Pharmacopoeia of the People's Republic of China (2015 version), volume IV.5 Test devicesIt shall include at least the following devices. a) Sterile cotton-swabs; b) Pressure steam sterilizer; c) (48 ± 2) °C constant-temperature water-bath; d) (35 ± 2) °C and (55 ± 2) °C bacteria incubator; e) A disposable or reusable sterile membrane filter which has a 0.45 μm pore size; f) Other devices or equipment as specified by the manufacturer of the sterilant, medical device or sterilizer.6 Reagents6.1 Purity of reagents 6.5 Neutralizer For the use of neutralizer, see the Pharmacopoeia of the People's Republic of China (2015 version), volume IV, for the microbiological limit inspection of 1105 non-sterile product. the description of the neutralizer in the microbiological counting method.7 Procedures7.1 Select the devices which require evaluation. 7.2 Read the cleaning instructions for the devices which require evaluation, ensure that all required accessories are complete and available. Follow the manufacturer's instructions to wash and dry the devices. 7.3 Infect the device, the infected part shall include the part of device which is most difficult to sterilize. The number of infected parts shall be determined based on the complexity of the device. The rationale for identifying and proving the parts of the device which are most difficult to sterilize shall be documented. 7.4 For procedures for contamination, elution, control testing, neutralization, growth promotion (sensitivity testing) and process testing cycles, the laboratory shall perform validation and develop standard operating practices. 7.5 Determination of the recovery control 7.5.1 Contamination of surface parts 7.5.1.1 Micropipette method Use a micropipette to directly drop an inoculum which contains more than or equal to 107 CFU onto the surface part to contaminate it. If the manufacturer specifies the drying requirements of the device prior to the aseptic process, dry the bacterial solution. Soak the instrument in the eluent or rinse it immediately or use a cotton-swab to wipe the infected parts, transfer it into a sterile test tube or other sterile container. Shake to mix it thoroughly. Perform gradient dilution, pipette 1 mL of the dilution of appropriate gradient into the culture dish, pour the molten agar medium which has been cooled to not exceeding 45 °C into a plate to which the sample solution had been added, 15 mL ~ 20 mL per plate. After the agar sets, it is cultured at a suitable temperature. Perform colony counts after 48 hours of culture, repeat counting every day until reaching to 7 d. Through selecting appropriate culture dish for counting, determine the average number of microorganisms per dilution grade, then use the dilution factor to calculate the total number of microorganisms on the contaminated device. Obtain the average of all replicated test data. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
