This International Standard specifies the essential characteristics for household refrigerator-freezers with or without cellar, which are wholly factory as-sembled, and lays down the methods of test for the checking of these characteristics.
It does not apply to refrigerator-freezers cooled by internal forced air circulation, which will form the subject of a future International Standard, except for the measurement of volumes.
Characteristics and methods of test for household refrigerators and for household frozen food storage cabinets and food freezers are covered in ISO 7371 and ISO 5155.
The tests described in this International Standard are type tests. When it is necessary to verify the performance of a refrigerator-freezer of a given type in relation to this International Standard, all the tests described should in principle be applied to one and the same unit.
These tests can also be made individually for the study of a particular characteristic.
Where no test method is specified, the particular requirement concerned shall be considered as a recommendation.
The safety requirements applicable to household refrigerator-freezers are specified in IEC 335-2-24.
Additional safety requirements applicable to me-chanical refrigerating systems of household refrigerator-freezers are given in ISO 5149.
The safety requirements applicable to gaseous and liquid fuel heating equipment of absorption type
household refrigerating systems will form the sub-ject of a future International Standard.
