prEN ISO 19424

Refrigerated food lockers - Thermal and energy performance, ratings, environmental test conditions and associated testing methods (ISO/DIS 19424:2025)

This standard specifies requirements for the thermal and energy performance of refrigerated food lockers, in given environmental conditions and intended for the temporary cold storage of chilled or frozen pre-ordered or pre-selected foodstuff until the final collection by the consumer.
The standard also covers construction characteristics relevant for the thermal and energy performance.
This standards specifies tests conditions and methods for checking the requirements to be satisfied, as well as classification of refrigerated lockers, their marking and the list of characteristics to be declared by the manufacturer.
This standard is not applicable to refrigerated vending machines,
It is also not applicable for commercial beverage coolers covered by ISO 22044, ice cream freezers covered by ISO 22043 and refrigerated display cabinets covered by ISO 23953 as well as to cabinets intended for storage or cabinets intended for use, for instance, in catering or non-retail refrigerated applications.
The standard does not cover any safety aspects.
The standard is not intended to specify the correct and/or hygienically safe storage temperatures for a specific foodstuff.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. 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 liaison 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 Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
