Measuring method of the energy consumption of gas fired ovens
This European Standard specifies the method of test for determining the gas energy consumption in gasfired domestic ovens when they are being used in one or more of the oven cooking modes defined in 3.1.
It applies to the gasfired domestic ovens which are capable of utilizing gases of group H or group E, or third family gases, possibly after conversion according to instructions for use.
This European Standard applies to these gasfired domestic ovens, whether they are separate appliances or component parts of domestic cooking appliances.
This European Standard also applies to domestic appliances that can utilize gas and/or electrical energy to provide heat for cooking when the ovens are utilizing gas energy to provide heat for cooking, but not when electric energy is used to provide any or all of the heat for cooking in the oven.
It is not applicable to:
— microwave combination ovens;
— small cavities ovens (3.2);
— oven cavities not provided with devices to detect and control the temperature for the preparation of food;
— cooking modes others than defined in 3.1.1 and 3.1.2;
This European Standard is concerned neither with safety nor with overall performance requirements.

European foreword
This document (prEN 15181:2025) has been prepared by Technical Committee CEN/TC 49 “Gas cooking
appliances”, the secretariat of which is held by UNI.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 15181:2017+A1:2020.
EN 15181:2017+A1:2020:
— new Table 1 with instrumentation;
— new Table 2 with measurements;
— preparation of the test load is fully described in Clause 6.2.2;
— the former clause with “Uncertainty and verification procedures” is removed.
This document has been prepared under a standardization request addressed to CEN by the European
Commission. The Standing Committee of the EFTA States subsequently approves these requests for its
Member States.
For the relationship with EU Legislation, see informative Annex ZA and Annex ZB, which are integral
parts of this document.
1 Scope
This document specifies the method of test for determining the gas energy consumption in gas-fired
domestic ovens when they are being used in one or more of the oven cooking modes defined in 3.1. It
applies to the gas-fired domestic ovens which are capable of using combustible gases described in
Clause 1 of EN 30-1-1:2021+A1:2023, possibly after conversion according to instructions for installation
and adjustment.
This document applies to these gas-fired domestic ovens, whether they are individual appliances or
component parts of domestic cooking appliances.
This document also applies to domestic gas cooking appliances incorporating electrical elements,
provided that these elements are not used for supplying heat for cooking during the measurement.
It is not applicable to:
— microwave combination ovens;
— small cavity ovens (as defined in 3.2);
— oven cavities not provided with devices to detect and control the temperature for the preparation of
food;
— cooking modes others than those defined in 3.1.1 and 3.1.2;
— ovens connected to a chimney in which the gas energy for cooking provides, by design, also space
and/or water heating.
This document does not cover neither safety requirements nor other overall performance requirements.

4 General conditions for measurements
4.1 General
Before installation, it shall be checked that the appliance is free from damage and complies with
soundness requirements given in EN 30-1-1:2021+A1:2023, 6.1.1.
The oven shall be installed according to the instructions for use installation.
Prior to every test, the whole appliance, including the insulation and the internal parts shall be at ambient
temperature.
In appliances with more than one cavity, each oven cavity shall be measured separately. Only the cavity
to be measured shall be switched on. Other electric heating elements shall not be switched on.
In case an oven has several cooking modes as defined in Clause 3, the manufacturer can choose the
cooking mode to be tested, provided there is no use of electrical elements for supplying heat for cooking.
4.2 Ambient temperature
The tests are carried out in a substantially draught-free room in which the ambient temperature is
maintained at (23 ± 2) °C during the complete test.
Before conducting the measurement the whole appliance, including the insulation and the internal parts,
shall be at an ambient temperature of (23 ± 2) °C.
This ambient temperature is measured at a point that is at the same height as the centre of the calculated
oven volume of the oven cavity and at a distance between 1 and 1,5
