There are a lot of dos and don'ts in this procedure.  The product's sterility assurance level is the probability that a viable microorganism is present on a product after sterilization. For sterilization, they mostly use steam under pressure, dry heat, and ethylene hydrogen oxide gas According to a classification, the equipment is classified into three critical, semi-critical, and non-critical categories. Essentially, critical equipment is those items that, if contaminated, are associated with a clinical risk of infection due to contact with the bloodstream or sterile tissues and, it is a must to be sterile to lead a good operation.  This category includes surgical instruments, catheters, needles, and implants, which must be sterile. Semi-critical equipment comes into contact with mucous membranes or healthy skin, such as tracheal tubes, laryngoscopes, and esophageal probes. These items and instruments must be sterilized. Non-critical equipment are those that only come into contact with healthy skin. , such as stethoscopes, blood pressure cuffs, and wheeled beds for patient transfer, these items can be disinfected with medium-level disinfectants.   Conclusions: Reaching a certain sterilization needs accurate monitoring during the preparation of equipment for sterilization.

The most important principle in concluding a contract is the possibility of its execution. The discussion of adjustment in the contractual implementation and the guarantee of its implementation is raised if after the conclusion of the contract due to reasons that are not attributable to the contracting parties, its implementation becomes impossible. Obstruction in contract execution is an important issue in most legal systems such as England, while there are differences regarding this issue.According to Article 229 of the Civil Code of Iran, the obligor is exempted from fulfilling the obligation. However, if due to the occurrence of accidents and changes in the circumstances at the time of the conclusion of the contract, the execution of the contract causes excessive difficulty or unusual loss for the obligee, and at the same time the execution of the obligation is not impossible, the law of our country does not provide a clear solution in this case. slowIn this article, we will do a comparative study of the conditions and obligation of the rule of default in Iranian law and the conditions of contract adjustment in English law and how to implement it and we will state the differences. In fact, the goal of achieving uniform rules based on comparative legal principles will be to create a uniform procedure for judicial courts.
