Foreword
This standard replaces GB/T 16259-1996 "color supplies artificial climate accelerated aging test method for color."
This standard compared with GB/T 16259-1996, the main changes as follows.
--- 4.1.3 This standard wavelength of 290nm ~ irradiance source selection (550 ± 50) 800nm \u200b\u200bbetween W/m2, the original standard gauge
Set at between 300nm ~ 890nm wavelength of the radiation intensity (1000 ± 200) W/m2;
The standard 5.2 --- choose between two black standard temperature (65 ± 3) ℃ and (100 ± 3) ℃, and the original standard black panel temperature
It was (63 ± 3) ℃.
The standard proposed by China Building Materials Federation.
This standard by the National Standardization whiteness standard sample Technical Working Group.

Supplies artificial climate accelerated aging test method
1 Scope
This standard specifies the supplies products to the xenon lamp as a light source artificial climate accelerated aging test equipment, test conditions, test procedures, test
Content and shows the results of the test reports.
This standard applies to the determination of the artificial climate accelerated aging of building materials.
2 Normative references
The following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent
Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research
Whether the latest versions of these documents. For undated reference documents, the latest versions apply to this standard.
GB/T 11942 color supplies color measurement method
GB/T 16422.1-1996 Plastics - Methods of exposure to laboratory light sources - Part 1. General
Principle 3
3.1 is equipped with a suitable filter xenon arc lamp maintenance was at that time, its spectrum UV radiation generated by the sun and the ground is similar to the visible region can
Weight distribution.
3.2 the sample is exposed to a light source specified environmental conditions.
3.3 Test procedure including irradiance and irradiance measured amount of the sample surface.
3.4 suggested a similar performance of known materials as a reference, and the material under test exposed simultaneously.
The results obtained 3.5 different types of devices should not be compared, unless the materials have been tested to determine the reproducibility of these devices in between.
4 test device
4.1 source
4.1.1 Spectral quartz tube Xe Arc lamp in the wavelength greater than 270nm including the ultraviolet, visible and infrared radiation.
To simulate the direct exposure to natural radiation sources must be filtered using a filter mask to provide a spectrum similar to daylight on earth can
Weight distribution (Method A), see Table 1.
Table 1 relative spectral irradiance of artificial weathering (Method A)
Relative spectral irradiance wavelength λ/nm /%
290 < λ≤800 100
λ≤290
290 < λ≤320
320 < λ≤360
360 < λ≤400

Note 1. 290nm ~ 800nm \u200b\u200bbetween the spectral irradiance as 100%.
When xenon light source operating according to the process A small amount of degradation of less than 290nm emitted radiation occur, in some cases, in outdoor exposure Note 2.
And it does not occur.
