Methods for measuring the performance of electric storage water heaters for household purposes

Scope

This document specifies methods for measuring the performance of electric storage water
heaters to produce domestic potable or non-potable hot water for household and similar use.
The object is to state and define the principal performance characteristics of electric storage
water heaters and to describe the test methods for measuring these characteristics.
NOTE 1 This document does not apply to:
• storage water heaters that use electricity as a secondary source of heating the water;
• storage water heaters that do not use a tank to store hot water;
• electric storage water heaters that do not meet the minimum (or maximum) output performance of the smallest (or biggest) load profile, as defined in Table 3;
• water-heaters without thermal insulation.
NOTE 2 This document does not specify safety requirements. For safety requirements, see EN IEC 60335-1 in
conjunction with EN IEC 60335-2-21.
