No other units of measurement are included in this standard.
It astm d5894 the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior satm use. Because of possible variability between the same type of exposure devices, it is not recommended to compare the amount of degradation in materials exposed for the same duration at separate times, or in separate devices running the same test condition.
Link to Active This link will always route to the current Active version of the standard. Different materials and different formulations astm d5894 the same material can have significantly different acceleration factors.
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 astm d5894 set of corrosive conditions. Results obtained from exposures conducted according to this practice can be considered as representative astm d5894 actual outdoor exposures only when the degree of rank correlation has been established for the specific materials being tested.
It does not specify specimen preparation nor evaluation of results. These factors frequently have a astm d5894 effect on one another.
astm d5894 Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. The relative durability of materials in actual outdoor service can astm d5894 very different in different locations because of differences in UV radiation, time of wetness, temperature, pollutants, and other factors.
Historical Version s – view astm d5894 versions of standard. 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 astm d5894 exterior environment, it cannot be astj that they will be useful for determining relative durability for a different environment.
Astm d5894 acceleration factor also varies depending on the variability in rate of degradation in the laboratory test and in actual outdoor exposure.
