Electric Radiant Heating Film for Low Temperature

1 Scope

This standard specifies the terms and definitions, classification and marking, requirements,

test methods, inspection rules, marking, packaging, operation instruction, transport and

storage of electric radiant heating film for low temperature.

This standard applies to electric radiant heating film for low temperature (hereinafter

referred to as electrothermal film) used for construction and heat supply. Rated voltage of

single-phase device does not exceed 250V; rated voltage of other industries does not

exceed 480 V. Electrothermal film for electrothermal heating in other industries may also

refer to this standard.

3 Terms and definitions

For the purpose of this standard, the following terms and definitions shall apply.

3.1

Electrothermal film

A kind of film that can generate heat after power-on. It is a planar heat generating

component that is composed of electrically insulating material and heat generating

resistor material encapsulated therein.

3.2

Electric radiant heating film

The electrothermal film that transfers electrical energy into thermal energy and passes

thermal energy out mainly in the form of radiation.

3.3

Flexible electrothermal film

The electrothermal film of which the electric insulating material is in flexible sheet.

3.4

Rigid electrothermal film

The electrothermal film of which the electrical insulating material is in rigid sheet (or plate).

3.5

power density

The power of unit-area on effective heating surface of electrothermal film.

3.6

Normal operation

The state of operating according to normal use conditions, when electrothermal film is

connected with the power.

3.7

After the test in 6.20, rigid electrothermal film shall not be broken and shall be able to

withstand electric strength inspection.

6 Test methods

6 1 General conditions for test

6 1.2 It is necessary to take 6 samples for test.

a) Tests in 6.9.6.10 and 6.11 are carried out on one sample.

b) Tests in 6.13 and 6.14 are carried out on one sample.

c) Tests in 6.15.6.16 and 6.17 are carried out on one sample.

d) Test in 6.18 is carried out on one sample.

e) Tests in 6.21 and 6.22 are carried out on one sample.

f) Other tests are carried out on the sixth sample.

Conduct in according with the method specified in 30.102 of GB 4706. 8-2003.

6 19 Impact test

Place electrothermal film on a level concrete floor and conduct the following test.

a) Make a Philips screwdriver of 140g fall freely from a height of 2m; falling direction

shall be ensured that the top of screwdriver can hit the surface of electrothermal film.

b) Make a iron ball of 500g fall freely from a height of 2 m to hit the surface of

electrothermal film; the test is conducted on two surfaces respectively.

After the tests in a) and b), observe the changes of electrothermal film and again conduct

electric strength test.

In electric strength test, aluminum foil of covering electrothermal film shall be able to cover

the impacted area.
