Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces QB/T 2164-1995 "Household and similar purposes fan type

PTCR heater". Compared with QB/T 2164-1995, the main differences are as follows.

- Modify the standard number of normative reference, terms and model naming

methods, inspection rules;

- Rewrite Chapter 5. delete the contents of test methods in the fifth chapter of QB/T

2164-1995, add the electrical strength and insulation resistance requirements of

the insulated heater, and modify the durability index of the heater;

- Add content in Chapter 6. modify the test methods in Chapter 5 of QB/T 2164-

1995 as the content of this chapter, and add the test methods of electrical strength

and insulation resistance of the insulated heater;

- Add demonstration of measurement and test methods in Appendix A (Informative).

This standard was proposed by the China Light Industry Federation.

This standard shall be under the jurisdiction of the National Household Electrical

Standardization Technical Committee (SAC/TC46).

Main drafting organizations of this standard. Ningbo Sunny Electronics Co. Ltd.,

Shenzhen Jinke special materials Co. Ltd., Shanghai Ziyu Electronic Ceramics Co.

Ltd., Weihai Haiwang Electronic Co. Ltd., Electronics Research Institute of

Chinese Academy of Sciences, Huazhong University of Science and Technology,

3 Terms and definitions

The following terms and definitions apply to this document.

3.1 Positive temperature coefficient resistance (PTCR)

The thermistor at its functional part, the resistance value increases with the increase

of temperature.

3.2 Fan type PTCR heater

A heater composed of one or more parallel PTCR elements and a metal radiator that

uses a mechanical method to circulate the air and heat it.

3.3 Zero-power resistance

The resistance of the heater at 25°C environmental temperature. It is measured under

the condition that the variation of resistance is caused by its internal heating and can

be ignored in the total deviation of measurement.

3.4 Maximum initial surge current

The valid value of the maximum current when the rated voltage is applied to a heater.

3.5 Withstanding voltage

The maximum voltage to which the heater can withstand during the specified time,

provided that the heater is not destroyed in the standard atmosphere and in the

stationary air.

3.6 Insulation heater

A heater that meets the requirements of specified insulation resistance and electrical

strength test.

After 6.4.2 test, the heater should have no obvious damage. The power change rate

should not be greater than 10%, and the change rate of zero-power resistance should

not be greater than 30%. The insulation heater should not breakdown during electrical

strength test.

insulation resistance should not be less than 100 Mohm.

6 Test methods

6.1 Test condition

6.1.1 Standard atmospheric conditions

Except for otherwise stipulated, all measurements and tests are carried out under the

standard atmospheric conditions specified in 5.3 of GB/T 2421.1-2008; in the case of

dispute, the standard atmospheric conditions for arbitration is.

a. Temperature. (25±1)°C;

b. Relative humidity. 48%~ 52%;

c. Atmospheric pressure. 86 kPa~ 106 kPa.

6.1.2 Reference temperature

Because the heater is sensitive to temperature change, the measurement and

calculation involve the reference temperature in the test. The ref...
