3 Terms and Definitions

In addition to the terms and definitions stipulated in GB 4706.1, GB 4706.23 and GB/T

15470-2002, this Part also adopts the following terms and definitions.

3.1 Multiunit heater

The composite appliance with at least 2 kinds of heating functions to heat the room.

4 Product Classification

4.1 Classification as per types

5.2 Appearance

5.2.1 The surface of electroplate part shall be fine, uniformly-colored, and exempted

from the following defects such as spots, peeling, threadbare, pinhole, bubbling,

obvious flaws and scratches, etc. After the corrosion resistance test, its surface, edges

and corners shall appear no rust point with diameter of 2mm above.

5.2.2 The surface of paint-coated (plastic-coated) parts shall be flat, light, uniformly-

colored, firm paining layer, strong adhesion; its main surface shall be exempted from

the following defects that affect the appearance such as flow-paint (flow-plastic), scars,

orange peels, primer exposed, cracks, peeling, etc.

5.2.3 The surface of plastic part shall be smooth, uniformly-colored, and exempt from

the obvious scars, scratches, or depression.

5.2.4 The nameplate and decorative plate of the heater shall be durable; after the

durability test, it shall be exempted from deformation, peeling; and its pattern and

writing are legible.

5.3 Length of power cord

For the heater with plug power cord, its power cord length shall be no less than 1.3m.

5.4 Start-up

For the heater with motor, under the 0.85 times of rated voltage, the motor can be

started-up normally.

5.5 Heating effect

5.5.1 The specific limits of the heating effect shall meet the special requirements of

the corresponding types of heater.

5.5.2 For the convection heater and fan heater, their heating effect shall be inspected

according to the temperature rise on the surrounding surface.

NOTE. the temperature rise on the surrounding surface indicates the temperature rise of the

measuring points around the heater.

5.5.3 For the plate heater, radiant heater and visible glowing radiant heater, their

heating effect shall be inspected according to the radiant temperature rise.

5.5.4 For the multiunit heater, its heating effect shall be inspected as per the heating

type by the temperature rise on surrounding surface and radiant temperature rise.

NOTE. the temperature rise on the surrounding surface indicates the temperature rise of the

measuring points around the heater.

Place the 1.5m-wide, 1.0m-high, 20mm-thick plywood coated berlin black on the

position where it forms right angle with the radiation direction of the heater; and at a

distance of 1m from the most protruding point at the furthest end on the external

surface of the heater radiation direction. The plywood center shall coincide with the

projection center of the heater radiation surface on the plywood.

As shown in Figure 4, separately arrange the 5 thermocouples on the center and at

the furthest end on the long and short shaft of the radiation projection surface.

Figure 5 is the radiation temperature-rise test schematic diagram.

Energize the heater; meanwhile use the temperature measurement and record

instrument to record the heating curve from the room temperature to the steady-state

temperature, which is shown in Figure 3.Record the measured temperature when the

steady-state is established.

When the steady-state is established, measure the temperature. Single-point

temperature-rise can be calculated by the difference between steady-state

temperature of the thermocouple on the plywood and the thermocouple initial

temperature. The above-mentioned 5-point temperature arithmetic mean is the

radiation temperature-rise, which shall be rounded to the nearest...
