PLN - Gas appliances for domestic use

This European Standard specifies the construction characteristics, performances and marking related to safety and the rational use of energy of portable, flat gas appliances directly supplied at the LPG vapour pressure, incorporating a gas cartridge complying with EN 417, inserted horizontally in the chassis. This European standards covers appliances for outdoor or in well ventilated areas uses only.

This document specifies the test gases, test pressures and categories of appliances relative to the use of gaseous fuels of the first, second and third families. It serves as a reference document in the specific standards for appliances that fall within the scope of the Council Directive on the approximation of the laws of Member States concerning gas appliances 2009/142/EC.
The standard makes recommendations for the use of the gases and pressures to be applied for the tests. The full procedure will be given in the corresponding appliance standards.
NOTE   The test gases and the test pressures specified in this standard are in principle intended to be used with all the appliances in order to establish conformity with the corresponding standards.
However, the use of some test gases and test pressures may not be appropriate in the following cases:
-   appliances with nominal heat input greater than 300 kW;
-   appliances constructed on site;
-   appliances in which the final design is influenced by the user;
-   appliances constructed for use with high supply pressures (notably direct use of the saturated vapour pressure).
In these cases, the specific appliance standards may specify other test conditions in order to establish compliance with their requirements.

This European Standard specifies a method for energy assessment of un-vented (closed) hot water storage tanks with a capacity up to 1 500 l, intended to be equipped with an external heat source and used for domestic hot water production. Whilst storage water heaters intended primarily for direct heating are not covered by this European Standard, it does allow the provision of electric heating elements for auxiliary use.

This European Standard is composed of two parts.
The first part supplements EN 303 1, EN 303 2, EN 303 4 and EN 304 hereafter called boiler standards. It specifies the supplementary requirements and tests for the construction, safety, rational use of energy, fitness for purpose, classification and marking related to the domestic hot water operation of oil fired water heaters and combination boilers.
The domestic hot water is produced on either the instantaneous or storage principle. The domestic hot water production is integrated or coupled, the whole being marketed as a single unit.
The second part covers the energy performance of domestic hot water production of the appliances covered by the first part.
This second part sets out a method for assessing the energy performance of the appliances. It defines a number of daily tapping cycles for each domestic hot water use such as kitchen, shower, bath and a combination of these, together with corresponding test procedures, enabling the energy performances of combination boilers and water heaters to be compared and matched to the needs of the user.

NOTE   These appliances are referred to in the body of the text as "appliances".
This document applies to various types of portable appliances burning liquefied petroleum gases at vapour pressure and designed to be used with cartridges as complying with EN 417 or gas cylinders.
This document covers appliances for outdoor or in well ventilated areas uses only.

a)   cooking appliances (stoves, grills, barbecues...);
This document does not cover barbecues that can be used indoors;
b)   lighting appliances;
c)   heating appliances;
This document only applies to appliances with a maximum heat input of up to 3 kW (Hs) for outdoor use only;
d)   blowtorches;

It does not apply to gas appliances operating with a valve cartridge which is horizontally integrated into the chassis of the appliance also called "flat portable gas stove".
Requirements for rational use of energy have been included for stove burners.
However, such requirements have not been included for the other types of appliances because:
-   for grills and barbecues, this is a type of cooking which is achieved by various means such as radiant elements; in addition this type of cooking varies according to the type of food and region where the appliance is used;
-   for lighting appliances, the consumption is insignificant because these appliances have a very low rate and are used only for a few hours in a year;
-   for heating appliances, all the heat produced is discharged into the environment;
-   for tools such as blowtorches which are not professional tools in regular use, the gas consumption depends very much on the way it is used.

The above appliances can have one or more primary or secondary functions (i.e. heat recovery - see definitions in prEN 12309 1:2012) and EN 12309 applies to all such functions providing that the function concerned is dependent on circulation of fluid (refrigerant and/or solution) within the absorption, adsorption or refrigerant circuit(s).
NOTE 1   Any appliance function that is not dependent on circulation of the fluid within the absorption, adsorption, or refrigerant circuit(s) should be assessed separately.
EN 12309 is applicable to appliances that are intended to be type tested. Requirements for appliances that are not type tested would need to be subject to further consideration.
In the case of packaged units (consisting of several parts), EN 12309 applies only to those designed and supplied as a complete package.
EN 12309 does not apply to air conditioners.
The appliances having their condenser cooled by air and by the evaporation of external additional water are not covered by EN 12309.
Installations used for heating and/or cooling of industrial processes are not within the scope of EN 12309.
NOTE 2   All the symbols given in this text should be used regardless of the language used.
Scope of this Part 7 to EN 12309
This part of EN 12309 specifies specific provisions for hybrid appliances for gas-fired sorption appliances for heating and/or cooling with a net heat input not exceeding 70 kW.
This part of EN 12309 deals particularly with the specific provisions of the newly introduced hybrid heating appliances based on gas-driven sorption heat pumps as defined in Part 1 and comprehensively described in 4.1 of this document.
