ASTM International recommends that a comparable material of identified performance a control be exposed at the same time as the test specimen. Control samples and multiple material samples produce the best comparative data.
This practice is intended to reproduce the weathering effects g514-06 occur when materials are exposed to sunlight either direct or through window glass and moisture as rain or dew in actual usage. Moisture takes its own toll on surfaces, and the combination of sunlight and moisture can amplify damage, costing millions of dollars of depreciation each year.
Therefore, no reference shall be made to results from the use of this practice unless accompanied by a report detailing the specific operating conditions in conformance with Section Different types of fluorescent UV light sources are described. This practice is limited to the procedures for obtaining, measuring, and controlling conditions of exposure.

A number of exposure procedures are listed in an appendix; however, this practice does not specify the exposure conditions best suited for the material to be tested. Element has been helping companies make Certain for over years. UV-B light accelerates the brittleness that materials, particularly polymers, may suffer as they age indoors. Link to Active This link will always route to the current Active version of the standard.
Overall, this test involves 21 days of exposure.
In xenon arc testing, different optical filters may be applied to shift testing conditions for daylight, window glass, or extended UV spectrum exposure. For instance, h154-06 exposure with no temperature cycling fails to recreate the expansion and contraction stress that materials face in outdoor locations.
However, each of these variables brings uniquely inaccurate results. Such outcomes cannot be quickly obtained in outdoor settings; therefore, these weatherization tests are invaluable in timely product development. Practice G describes performance criteria for all exposure devices that use laboratory light sources.
A QUV test chamber uses fluorescent g1544-06 to provide a radiation spectrum centered in the ultraviolet wavelengths. For instance, a slight shift in formula may produce twice as much resistance to weathering.

Therefore, these bulbs are useful for testing interior applications. Generally, two controls are recommended: No direct correlation can be made between accelerated weathering duration and actual outdoor exposure duration. Auditing Consulting Sourcing Training. The apparatus described in Practice G 53 is covered by this practice.

Warning— Refer to Practice G for full cautionary guidance applicable to all laboratory weathering devices. Gg154-06 for weatherization testing will vary according to a number of factors, including moisturization, sample size, number of cycles, and more.
See Guide D for guidance. Different types of fluorescent UV lamp sources are described.
Hemispherical on 37 Tilted Surface. Our Engaged Experts can help you select the best UV bulbs for your testing purposes. This allows for accurate comparison. This practice is limited to the procedures for obtaining, measuring, f154-06 controlling g1540-6 of exposure.
Xenon Arc Testing Weatherometers used in the G and G tests approximate performance via intense exposure to the damaging elements in sunlight. This practice replaces Practice G 53, which describes very specific designs for devices used for fluorescent UV exposures.
