This document (prEN 556-2:2023) has been prepared by Technical Committee CEN/TC 204 “Sterilization
of medical devices”, the secretariat of which is held by BSI.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 556-2:2015.
This document has been prepared under a Standardization Request given to CEN by the European
Commission and the European Free Trade Association, and supports essential requirements of EU
Directive(s) / Regulation(s).

integral part of this document.
For relationship with EU Directive(s), see informative Annexes ZA and ZB, which are integral parts of this
document.
EN 556, Sterilization of medical devices — Requirements for medical devices to be designated ''STERILE", is
currently composed with the following parts:
— Part 1: Requirements for terminally sterilized medical devices;
— Part 2: Requirements for aseptically processed medical devices [this document].
EN 556-2:2023 includes the following significant technical changes with respect to EN 556-2:2015:
— definitions have been aligned with ISO 11139;
— the normative reference has been updated to the latest edition;
— informative Annex ZA has been replaced with Informative Annexes ZA and ZB giving the relationship
with the European Regulations for medical devices and in vitro diagnostic medical devices
respectively;
— the Bibliography has been updated.

Introduction
Medical devices designated 'STERILE' are prepared using appropriate and validated methods. Whenever
possible, sterile medical devices are terminally-sterilized using a properly validated and controlled
sterilization process (see EN 556-1, EN ISO 11135, EN ISO 11137-1, EN ISO 14160, EN ISO 14937,
EN ISO 17665-1, EN ISO 20857 and EN ISO 25424). When a medical device is intended to be sterile but
cannot be terminally sterilized, aseptic processing is the method of manufacture (see EN ISO 13408-1).
Aseptic processing necessitates that either:
a) the entire product is sterilized and then introduced into a sterilized package; or
b) components of the product are sterilized, then further processed/assembled, and the final product
packed into a sterilized package.
Processing/assembly and packaging are carried out in a manner that minimizes the opportunity for items
to become re-contaminated by carrying out these operations in a controlled environment in which
microbial and particulate levels are maintained at or below defined limits and human intervention is
minimized.
NOTE EN ISO 15223-1 specifies the label applied to aseptically processed medical devices as “STERILE A”.

1 Scope
This document specifies the requirements for an aseptically processed medical device to be designated
'STERILE'.
NOTE For the purpose of the EU Directive(s) for medical devices (see Bibliography), designating that a medical
device is 'STERILE' is permissible when a validated manufacturing and sterilization process has been applied.
Requirements for validation and routine control of aseptic processes are specified in EN ISO 13408-1. Specific
requirements for the aseptic processing of solid medical devices and combination products are specified in
ISO 13408-7.
