Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

In the following, general testing conditions which are common for all tests specified in Clause 6 carried

out inside the test room are defined. These conditions concern the test room, the test and M-packages,

and the measuring instruments.
5.3.2.2 Test room — General design, walls, floor and radiant heat

The test room shall be a parallelepiped space. The walls of the room shall be thermally insulated.

The minimum dimensions of the test room shall be such as to allow at least 0,5 m above the top of the

cabinet, 1 m on the side of the climate measuring point, 0,5 m on the opposite side and 1,5 m on the

front of the cabinet with doors in closed position (see Figure 4).

A minimum insulation level equivalent to 60 mm of rigid polyurethane foam (λ = 0,03 W/m °C) should

be used for the building of the test room.

The floor shall be made of concrete or of thermally equivalent material and/or shall be sufficiently

insulated to ensure that external climatic conditions do not affect the floor temperature.

Lighting shall be installed to maintain (600 ± 100) lx measured at a height of 1 m above the floor level

and shall be lit continuously during the test period.

The walls, ceilings and any partitions of rooms intended for the testing of refrigerated cabinets shall

have an emissivity between 0,9 and 1 at 25 °C.
5.3.2.3 Test room climate definition
5.3.2.3.1 Test room climate classes
Tests shall be carried out in one of the climate classes according to Table 3.

During the test, the test room shall be capable of maintaining values of temperature and humidity

within ±1 °C of the temperature and ±5 units of the relative humidity percentage figures at the specified

climate measuring point(s).

NOTE The water vapour mass in dry air is one of the main points influencing the performance and the energy consumption

of the cabinets.
5.3.2.3.2 Climate measuring point

The climate measuring point shall be located in the test room air flow, 500 mm upstr
