ASTM G154 and G155 Explained
No other units of measurement are included in this standard. Astmm xenon arc y154-06, different optical filters may be applied to shift testing conditions for daylight, window glass, or extended UV spectrum exposure. This practice is limited to the procedures for obtaining, measuring, and controlling conditions of exposure. Formally confirming that your products and services meet all trusted external and internal standards.
This standard does not purport to address all of the safety concerns, if any, associated with its use.
ASTM G and G Explained | Element
UV-B light accelerates the brittleness that materials, particularly polymers, may suffer as they age indoors. Different types of fluorescent UV lamp sources are described.
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. In this standard, the terms UV light and UV radiation are used interchangeably. Through our network of over 43, people in 1, laboratories and offices in countries, Intertek provides quality and safety solutions to a wide range of industries around g54-06 world.

Accelerated Weathering (QUV) ASTM G154, ASTM D4329, ASTM D4587, ISO 4892
Active view current version of standard. Costs for weatherization testing will vary according to a number of factors, including moisturization, sample size, number of cycles, and more.
There is no easy exposure formula. Parts may be accommodated depending on size.
This practice replaces Practice G 53, which describes very specific designs for devices used for fluorescent UV exposures. Up to 20 test samples are mounted in the QUV and subjected to a cycle of exposure to intense ultraviolet radiation followed by moisture exposure by condensation. Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.
Note 1 Practice G describes performance criteria for all exposure devices that use laboratory light sources. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
If the aim of testing is to boost color fastness, UV-A bulbs are ideal. In contrast, UV-A bulbs have a propensity for accelerating color fading and yellowing.
Without testing in a specific location over a number of years, it is impossible to perfectly predict product response. We provide Xenon Arc testing, Carbon Arc testing and UV Exposure testing to simulate exposure of your products or materials to ultraviolet radiation, temperature and moisture.

Accelerated Weathering (QUV) ASTM G, ASTM D, ASTM D, ISO
In the ASTM G test, xenon arc lamps simulate full-spectrum sunlight within a controlled test chamber. Remember, these accelerated weatherization tests cannot exactly reproduce outdoor conditions, as they cannot account for altitude, seasonal variations, local geographical features, and other variables.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Moisture is provided by forced condensation, and temperature is controlled by heaters.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. We can work with you to ascertain the most cost-effective, accurate testing approach for your material.
