Foreword
GB/T 5137 "Test methods of safety glazing materials used on road vehicles" is divided
into 4 parts.
- Part 1. Test methods of safety glazing materials used on road vehicles. Part 1.
mechanical properties tests
- Part 2. Test methods of safety glazing materials used on road vehicles. Part 2.
optical properties tests
- Part 3. Test methods of safety glazing materials used on road vehicles. Part 3.
radiation, high temperature, humidity, fire and simulated weathering
resistance tests
- Part 4. Road vehicles. Safety glazing materials. Method for the determination of
solar transmittance
This Part is part 3 of GB/T 5137.
This Part of GB/T 5137 modifies and adopts ISO 3917.1999 "Road vehicles - safety
glazing materials - Test methods for resistance to radiation, high temperature, humidity,
fire and simulated weathering" (English edition).
The main differences between this Part and the international standard are as follows.
- DELETE the test requirements relevant to plastic glass materials;
- DELETE the requirements of open-flame carbon arc lamp device in simulated
weathering test;
- DELETE the requirements of test report description in simulated weathering test
items.
This Part replaces GB/T 5137.3-1996 Test methods of safety glazing materials used
on road vehicles Part 3. radiation, high temperature, humidity, fire and simulated
weathering resistance tests.
Compared with GB/T 5137.3-1996, there is no technical change in this Part, except
that – in order to maintain the consistency of each test, DELETE the description of the
test report in previous standard.
This Part was proposed by the former State Bureau of Building Materials Industry.
This Part shall be centralized by the National Standardization Technical Committee
Automotive Safety Glass Sub-technical Committee.
Main drafting organization of this Part. Glass Science and Special Glass Fiber Institute
of China Building Materials Academy.
The main drafters of this Part. Wang Rui, Wang Wenbiao, and Zhou Junyan.
The previous editions replaced by this Part are.
GB 5137.3-1985, GB/T 5137.3-1996.
GB 17326-1998
Test methods of safety glazing materials used on road
vehicles - Part 3. radiation, high temperature, humidity, fire
and simulated weathering resistance tests
1 Scope
This Part of GB/T 5137 specifies the test methods of safety glazing materials used on
road vehicles - radiation, high temperature, humidity, fire and simulated weathering
resistance.
This Part applies to automotive safety glass (hereinafter referred to as safety glass). It
includes those glass products which are processed by various types of safety glass or
which are combined of glass and other materials.
2 Reference standards
The following documents contain provisions which, through reference in this Standard,
become provisions of this Standard. For dated references, their subsequent
amendments (excluding corrections) or revisions do not apply to this Standard.
However, the parties who enter into agreement based on this Standard are
encouraged to investigate whether the latest versions of these documents are
applicable. For undated reference documents, the latest versions apply to this
Standard.
GB/T 5137.1-2002 Test methods of safety glazing materials used on road
vehicles. Part 1. mechanical properties tests (ISO 3537.1999, MOD)
GB/T 5137.2 2002 Test methods of safety glazing materials used on road
vehicles. Part 2. optical properties tests (ISO 3538.1997, MOD)

3 Test conditions
Unless otherwise specified, the test shall be carried out under the following conditions.
a) Ambient temperature. 20 °C ± 5 °C;
b) Atmospheric pressure. 8.60 × 104 Pa - 1.06 × 105 Pa;
c) Relative humidity. 40% - 80%.
GB 17326-1998
4 Test application
For certain types of safety glazing materials, if the test results can be predicted
according to the certain known properties, then it is not necessary to carry out all the
tests specified in this Part.
5 Radiation resistance test
5.1 Test purpose
After the safety glass is radiated for certain period of time, DETEMINE whether there
is any obvious discoloration or decrease in transmittance phenomenon.
5.2 Apparatus
5.2.1 Radiation source
It is consisted of a medium pressure mercury arc lamp with a tubular quartz bulb of
ozone-free. The bulb axis shall be vertical. The nominal dimensions of the lamp shall
be 360 mm in length, and 9.5 mm in diameter. The arc length shall be 300 mm ± 14
mm. The operating power is 750 W ± 50 W.
Any other source of radiation which produces the same effect as the lamp specified
above may be used. To check that the effects of another source are the same, a
comparison shall be made. The method is to measure the amount of energy emitted
within a wavelength range of 300 nm to 450 nm, all other wavelengths being removed
by the use of suitable filters. Therefore, alternative source shall be used with filters.
For the safety glass for which there is no satisfactory correlation between this test and
the conditions of use, it must re-consider the test conditions.
5.2.2 Power supply transformer and capacitor
It shall be capable of supplying a starting-peak voltage of 1100 V minimum and an
operating voltage of 500 V ± 50 V to the arc lamp.
5.2.3 Test specimen fixing and rotating devices
It is rotated around the radiation source mounted at the axis, at speed of 1 r/min - 5
r/min, so as to ensure the even radiation.
5.3 Test specimen
Dimension. 76 mm x 300 mm.
5.4 Test procedure
GB 17326-1998
However, the light reflected from the chamber wall is not allowed to fall onto the back
od the specimen. If necessary, under the conditions of not affecting the free air
circulation of specimen surface, the specimen may be installed with back-cover to
block such reflected light.
9.4.6 Specimen apparatus shall be able to maintain continuous light radiation and
intermittent spray - pure light radiation for 102 min and spray light radiation for 18 min
within 2h cycle period.
9.4.7 After the end of the test, CLEAN the test specimen according to the requirements.
Or REMOVE the residue from the specimen surface according to the method
recommended by the manufacturer.
9.5 Result judgment
9.5.1 EVALUATE the following situations of the specimen through inspecting the
appearance quality.
a) Bubble;
b) Color;
c) Turbid;
d) Unglued.
9.5.2 According to the provisions of GB/T 5137.1-2002 and GB/T 5137.2-2002,
DETERMINE the abrasion resistance and transmittance after its exposure.
9.6 Expression of results
After the test, RECORD the appearance quality of the specimen. And COMPARE with
the appearance quality of the specimen before test. SUBMIT the change result report
of determined abrasion resistance and transmittance before and after the specimen is
exposed.
