No other units of measurement are included in this standard.
Historical Version s – view previous versions of standard. Different materials and different formulations of the same astm d5894 can have significantly different acceleration factors.
This practice is intended to d58894 a more realistic simulation of the interaction of these factors than is astm d5894 in traditional tests with continuous exposure to a static set of corrosive conditions. Link to Active This link will always route to the current Active version of the standard. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but astm d5894 not provided as part of the standard.
Astm d5894 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, astm d5894 other factors. 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.
Results astm d5894 from exposures conducted according to this practice can be considered as representative of actual outdoor exposures only when the degree of rank astm d5894 has been established for the specific materials being tested.
These factors frequently have a synergistic effect on one another.
Therefore, even if results from a specific artificial test condition are 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 dd5894 determining relative durability for a different environment. Because of possible variability between the same type of exposure devices, it is not recommended to compare the amount astm d5894 degradation in materials exposed for the same duration at separate astm d5894, or in separate devices running the same test condition.
The acceleration factor also varies depending on the variability in rate of degradation in the astm d5894 test and in actual outdoor exposure.
It does not specify specimen preparation nor evaluation of results.
