European foreword
This document (prEN 12778:2019) has been prepared by Technical Committee CEN/TC 194 “Utensils in
contact with food”, the secretariat of which is held by AFNOR.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 12778:2002.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this
document.
Minor revision has been included to take into account the requirements specified in the Pressure
Equipment Directive 2014/68/EU.

1 Scope
This document defines terms, establishes manufacturing, safety and functional requirements and
corresponding tests, and specifies data for marking, labelling and instructions for use, for pressure
cookers.
This document is applicable to portable pressure cookers for domestic use, with gross volume up to 25 l,
with working pressure over 4 kPa and less than 150 kPa, with either integrated or independent heating.
NOTE All pressures mentioned in this text are related to atmospheric pressure.

3.1
pressure cooker
cookware equipped with a removable lid being able to be fitted, specifically for the purpose of allowing
cooking of foodstuffs by water and/or steam under pressure
Note 1 to entry: It can be used on a stovetop or can be equipped with an integrated heating source.
3.2
capacity
volume of water held when the pressure cooker, without the lid, is filled to the brim while standing on a
level surface

carried out to open the pressure cooker
3.13.2
automatic system
system which automatically prevents the pressure cooker from being opened if the internal pressure is
