Summary

  鉴于大量的影响参数和由此产生的复杂相互关系，以及不同影响因素的平行效应，负责消毒设备的人员往往发现在实践中很难确定实际导致腔室内部不锈钢表面（不希望的或麻烦的）改变的具体原因。

   In light of the large number of influencing parameters and the resulting complex interrelations, and because of the parallel effects of different influencing factors, individuals in charge of sanitizing equipment often find it very difficult in practice to determine the specific cause that has actually led to an (undesired or bothersome) alteration of the stainless steel surfaces located in the interior of a chamber.

  本手册的目的是描述并说明被称为红锈的消毒器室表面变化的现象。还描述了在实际中成功实施的措施。在所有所涵盖的方法中，设备用户、设备制造商和专业清洁公司之间的积极和专注的协作是一个恒定的要求。 

     The aim of this brochure is to describe and identify the phenomenon known as rouging as a change in the surfaces of sterilizer chambers. Measures which have already been successfully implemented in practice are also described. In all of the methods covered, an active and focused collaboration between equipment users, the equipment manufacturer and the specialist cleaning company is a constant requirement.
