IS 17550 : Part 1 : 2024 Household Refrigerating Appliances - Characteristics and Test Methods - Part 1 General Requirements
| ICS 97.030; 97.040.30 | MED 03 |
1 SCOPE
1.1 This Indian Standard (Part 1) specifies the essential characteristics of household and similar refrigerating appliances, cooled by internal natural convection or forced air circulation, their rated voltage not exceeding 250 V, 50 Hz a.c., and establishes test methods for checking the characteristics.
1.2 The tests defined in this standard are meant to assess the fundamental design and operation of a refrigerating appliance.
NOTE - Annex G lists the items that can be included in a test report.
1.3 For the verification of the performance of a refrigerating appliance of a given type it is preferable, wherever practicable, that all the tests specified are applied to a single unit. The tests can also be made individually for the study of a particular characteristic.
1.4 Refrigerating appliances conforming to this standard are classified into T class instead of four climate class. The range of ambient temperatures in which the appliances are intended to be used, and for which the required storage temperatures are to be met is specified in Table 1.
NOTE - The climate class in India is considered a T Class.
1.5 This standard shall be read in conjunction with the requirements given in Part 2 and Part 3 of this standard.
1.6 The requirement of ECO-Mark criteria is given in Annex J of this standard. The requirement of ECO-Mark is optional.
