Foreword

 

This European Standard was prepared by the German national committee under supervision of the Technical Committee CENELEC TC 59X, Consumer information related to household electrical appliances.

It describes methods for checking the performance of hydraulic, closed electrical instantaneous water heaters for household use and other criteria which are of particular importance for the consumer. For the time being it does not deal with the measuring of energy consumption.

The text of the draft was submitted to the formal vote and was approved by CENELEC as EN 50193 on 1996-12-09.

 

The following dates were fixed:

- latest date by which the EN has to be implemented

at national level by publication of an identical

national standard or by endorsement                     (dop) 1997-12-01

- latest date by which national standards conflicting

with the EN have to be withdrawn                        (dow) 1997-12-01

 

Annexes designated „normative" are part of the body of the standard.

In this standard, annex A is normative.

1 Scope

 

This standard applies to hydraulic, closed electrical instantaneous water heaters, for household and similar use.

This standard does not apply to storage water heaters (HD 500 S1) and to instantaneous water heaters with electronically controlled power input.

This standard specifies definitions and measurement methods for assessing the performance characteristics. It does not deal with safety requirements which are covered by EN 60335-2-35.

 

NOTE: Test methods for open outlet and electronically controlled instantaneous water heaters are under consideration.
