3. Terminology
3.1 Black Panel Thermometer, n元宵手抄报简单
A temperature measuring device, the nsing unit of which is coated with black enamel designed to absorb most of the radiant energy encountered in fade/weathering testing.
3.2 Black Standard Thermometer, n
See ASTM G 147 for definition.物流实习周记
NOTE—The devices provide an estimation of the maximum temperature a specimen might attain during exposure to natural or artificial light.
3.3 Definitions applicable to this standard can be found in ASTM G 151.
4. Significance and U
4.1 This test method is designed to simulate extreme environmental conditions encountered inside
vehicle due to sunlight, heat, and humidity for the purpo of predicting the performance of
automotive interior trim materials.
5. Apparatus
5.1 The equipment manufacturer is responsible for the approval of the equipment and for providing the
proof of compliance of the critical test parameters, including the different spectral power
distributions (SPDs) that are required by contractual parties. Materials ud for the compliance testing should include the approved lots of standard reference materials, such as the Testfabrics polystyrene and/or the AATCC L4 & L2 Blue Wools as appropriate. It is the responsibility of the instr
ument manufacturer to provide all necessary data to demonstrate compliance of each model type with this specification. At the minimum, the data should include (1) all the pertinent spectral power distribution (SPD) data for 250 nm - 800 nm, and (2) repeatability and reproducibility data for the current approved lots of standard reference materials. Contractual parties should agree upon the instrument model prior to testing.
NOTE—In normal practice, different instruments may give different results. The result depends on sample characteristics and instrument design. Refer to ASTM G155 Section 4.3 and 4.4 for
more information.
5.2 The apparatus employed utilizes a xenon-arc lamp(s) as the source of radiation. The specimens
那尔那茜shall be mounted in a manner to expo the specimens to the uniform conditions of the test
高中生破处chamber. The instrument must have the means to automatically control irradiance, Black Panel temperature, chamber temperature and relative humidity. Contractual parties shall agree upon the manufacturer and model of the instrument before testing begins.
5.2.1 A more complete description of the apparatus can be found in ASTM G151 and ASTM G155.
5.3 The apparatus must have an uninsulated black panel thermometer as described in ASTM G151
unless otherwi agreed upon by contractual parties.
5.4 Manufacturers of exposure devices shall assure that the irradiance at any location in the area ud
for specimen exposures is at least 70% of the maximum irradiance measured in this area.
5.4.1
I f irradiance at positions farthest from the center of the exposure area is between 70% and 90%
谈读书议论文of that measured at the center, place specimens only in exposure area where irradiance is at
什么主板最好least 90% of the maximum irradiance.
