TRYC B-D Test Pack

method of application

1. The sterilizer is preheated to a suitable temperature.
2. In the case of an empty pot, place the test package above the exhaust port, near the door, with the label facing up and flat.
3. When the sterilizer is operated for 5 minutes (132℃ or 134℃), any overtime work will affect the B-D test results. If the sterilizer is operated for more than 4 minutes, the sensitivity of the test paper will decrease, and false negative results will be observed.
4. After the cycle, check the BD test paper.
5. Interpretation method: After passing, the BD test paper becomes uniform dark brown to black, and the BD test is qualified at this time; Failure, there is a bright area in the middle of BD test paper, the color is uneven, and BD test is unqualified, so follow-up treatment should be carried out according to the requirements of national standards. Passing result: B-D test paper turns into uniform dark brown to black, which is the passing test result. It shows that the air in the sterilizer is removed and the steam penetration effect is good. The result of failure: there is a bright area in the middle of the twill of B-D test paper, which shows uneven color, which is caused by the cold air mass in the sterilizer room, indicating that the air is removed and the effective penetration of steam is prevented. If uneven color change is found, it must be reported to the supervisor immediately, and the sterilizer must be repaired until it is qualified for troubleshooting. Overexposure: If the test paper is gray or silver, it means overexposure (the time or temperature exceeds the standard), which means that the test is invalid and needs to be retested.
