Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in l

32、iaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC D

33、irectives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted.

38、est methods and performance requirements for the manufacture of biological indicators including inoculated carriers and suspensions intended for use in validation and monitoring sterilization processes. This document gives specific requirements for those biological indicators intended for use in low

39、-temperature steam and formaldehyde sterilization processes.Annex B gives rationale for the liquid-phase test method for low-temperature steam and formaldehyde biological indicators.The ISO 11138 series represents the current “state-of-the-art” according to the experts representing manufacturers, us

40、ers and regulatory authorities involved in developing the standard. The intent is not to promote the use of biological indicators where such use is not advised, but to provide common requirements for the production of those biological indicators that are known to be in use today.A standard exists pr
