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.
5.20 Electric-to-radiant power transfer efficiency
Electric-to-radiant power transfer efficiency of electrothermal film shall not be less than
55%.
5.21 Working life
Accumulated working time of electrothermal film under normal working state shall not be
less than 30 000 h.
6  Test methods 
6. 1 General conditions for test
6.1.1 The test shall be carried out under the following conditions.
a) Temperature controllers sensitive to temperature are not taken into consideration;
b) For electrothermal film that requires on-site cutting, the test shall be carried out after
connection to supply lead and its edges protection;
c) Ambient temperature is 20°C ±5°C;
d) Relative air humidity is not greater than 85%;
e) There is no significant air convection in the laboratory;
f) Length of electrothermal film length is better to be between 500mm and 1 000mm;
the width is according to manufacturer’s instructions; test-sample preparation in
6.14 and 6.18 is in accordance with provisions of the test method.
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.
6.20 Drop test
Put electrothermal film in a low temperature test chamber at a temperature of -15°C±2°C;
keep for 4 h and take out; lift it to a height of 2 m away from the cement ground and make
free vertical drop. After the test, observe the changes on surface; make it recover for 1 h
at room temperature and then conduct electric strength test.
6.21 Electric-to-radiant power transfer efficiency
Conduct in accordance with the method specified in chapter 17 of GB/T 7287-2008.
6.22 Operation life test
Conduct in accordance with the method specified in chapter 22 of GB/T 7287-2008.
Accelerated aging test is carried out in accordance with the actual installation conditions
specified in product operation instructions.
Test time is 360 h.
After the test is completed, if the outer surface of sample meets the requirements of 5.2,
the leakage current is not greater than 3.5 mA, electric strength is not lower than the
standard value, deviation of actual power does not exceed ±10%, electric-to radiant power
transfer efficiency is not lower than 90% of initial value, then it is determined that the
service life of this sample is not less than 30 000 h.
