prEN ISO 19253

Specifies the requirements and the relevant tests for sterilizers intended to be used for the terminal sterilization of health care products (medical devices or medicinal products) presented as aqueous liquid in sealed containers. The container can be rigid, semi rigid or flexible. The sterilizing agent, moist heat, is created internally from the product, heating being achieved by use of saturated steam, mixtures of steam and a pressure ballasting non-condensing gas such as air or super-heated water in the sterilizer chamber. The sterilizers can be used in both a health care and industrial setting.
This standard does not apply to sterilizers using saturated steam for the sterilization of the surfaces of medical devices or sterilizers used in laboratories.
NOTE 1  Sterilizers using saturated steam for sterilizing the surfaces of medical devices are covered by EN 285 and EN 13060. Laboratory sterilizers are covered by some national standards.
NOTE 2  Sterilizers conforming to NWIP ISO XXXXX can also be used for the sterilization of other aqueous liquid in sealed containers such as veterinary products or some foodstuffs.
Note 3 Sterilizers conforming to NWIP ISO XXXXX can also be used for the sterilization of a contained product enclosed within a sterile barrier system conforming to the EN ISO 11607 series of standards.
