11.3 Appliance categories
Labelling of gas and dual fuel burners to EN 676
EN 676, "Forced draught burners for gaseous fuels", is used for the implementation
of the basic requirements of the directive (EU) 2016/426.
EN 676 stipulate the following appliance categories for forced draught gas burners
under Point 4.4.9:
I2R
for Natural Gas
I3R
for Liquid Petroleum Gas
II2R/3R
for Natural Gas / Liquid Petroleum Gas
The test gases listed under point 5.1.1, table 4 and the minimum test pressures
determined and listed under point 5.1.2, table 5 are used to provide the evidence
of service performance of the burner during type testing.
As -weishaupt- gas and dual fuel burners fulfil this requirement completely, the ap-
pliance category, as well as the test gases used with the permissible connection
pressure range, are listed on the name plate when labelling the burner to point 6.2 .
This clearly defines the suitability of the burner for use with second or third family
gases.
On the basis of a type test report to ISO 17025 from an accredited test centre, the
EU Type Testing Certificate to Directive (EU) 2016/426 also quotes the appliance
category, the supply pressure and the country of destination.
EN 437, "Test gases - test pressures - appliance categories", describes the inter-
relationships and the special national characteristics relating to this subject in de-
tail.
The following tables give an overview of the interrelationships between the R Cat-
egories and the nationally used appliance categories with their types of gas and
connection pressures.
