1 Modification to Clause 1, “Scope”
Replace the content of Clause 1 with the following:
“This document applies to electric storage heaters having a daily operating cycle and intended to heat the room
in which they are located.
NOTE 1 This document does not apply to heating appliances incorporated in the building structure, to central heating
systems or to floor heating installations.
NOTE 2 If an appliance is intended to be operated as a storage heater or as a direct-acting room heater, it is also tested
in accordance with EN 60675.
NOTE 3 If an appliance has a heat retention of less than 20 %, it is not considered to be a storage heater.
This document defines the main performance characteristics of storage heaters and specifies methods for
measuring these characteristics, for the information of users.

3.1
local space heater
device equipped with one or more heat generators to convert electricity from the mains or gaseous or liquid
