It is the astm d5894 of the user of this standard to establish appropriate safety and astm d5894 practices and determine the applicability of regulatory limitations prior to use. Different materials and different formulations of the same material can have significantly different acceleration factors.

These factors frequently have a synergistic effect on one another. Therefore, even if results from a specific artificial test condition astm d5894 found to be useful for comparing the relative durability of materials exposed in a particular exterior environment, it cannot be assumed that they will be useful for determining relative durability for a different astm d5894.

Results astm d5894 from exposures astm d5894 according to this practice can be considered as representative of actual outdoor exposures only when the degree of rank correlation has been established for the specific materials being tested.

No other units of measurement are included in sstm standard.

Because of possible variability between the same type of exposure devices, it is not recommended to compare the amount of degradation in materials exposed astm d5894 the same duration at separate times, or in separate devices running the same test condition. This practice is intended to provide a more realistic simulation of the interaction of these factors than is found in traditional tests with continuous exposure to a static set of corrosive conditions. astm d5894

Referenced Documents astm d5894 separately The documents listed below are referenced within the subject standard but are astm d5894 provided as part asgm the standard. The relative durability of materials in actual outdoor service can be very different in different locations because of differences in UV radiation, time of wetness, temperature, pollutants, and other factors.

The acceleration factor also varies depending on the variability in rate of degradation in astm d5894 laboratory test and in actual outdoor exposure.
