introduction
GB 18281.1 provides biological indicator production, labeling, test methods and performance requirements for these indicators is expected to contain sterilized
Ranjun carrier confirmation process and routine control and bacterial suspension. This section provides special procedure for ethylene oxide sterilization of biological indicator
Use requirements.
GB 18281 provides general requirements and test methods. This standard is to participate in professional manufacturers, users and regulators to develop.
The purpose of this standard is not to promote the development in the case is not recommended the use of biological indicators, but for biological indicator currently used to provide
specification.
Ethylene oxide sterilization Validation and routine control See GB 18279.
Select the biological indicator, use and test results to determine see GB/T 19972.
Sterilization of health care products - Biological indicators
Part 2. Biological indicators for ethylene oxide sterilization was
1 Scope
GB 18281 of the provisions of this part of the test organisms intended when evaluating the performance of the sterilizer and sterilization processes used, bacterial suspension, carrying contamination
Body, special requirements and test methods for biological indicator, which uses pure ethylene oxide sterilization or it is mixed with other dilution gas sterilization,
Sterilization temperature range is 29 ℃ ~ 65 ℃.
Note 1. ethylene oxide sterilization confirmation and routine control See GB 18279.
Note 2. workplace safety reference to the relevant provisions of the State.
