Link to Active This link will always route to the current Active version of the astm d5894. Different materials and different formulations of the same material astm d5894 have significantly different acceleration factors. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

These factors frequently have a synergistic astm d5894 on one another. 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 astm d5894 running the same test condition.

This practice is intended to provide a more realistic simulation astm d5894 the interaction of these factors than is found in traditional tests with continuous exposure to a static set of corrosive conditions. The acceleration factor astm d5894 varies depending on the variability in rate of degradation in the laboratory test and in actual outdoor exposure.

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 astm d5894 assumed that they will be useful for determining relative durability for a different environment.

It is the responsibility of the user of this standard to establish appropriate safety and health d58944 and determine the applicability astm d5894 regulatory limitations prior to use.

Results obtained from exposures conducted according to this practice can be considered as representative of actual outdoor astm d5894 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.

Historical Version s – view previous versions of standard. The relative durability of materials in actual outdoor service can be very different in different locations because of differences in UV radiation, time astm d5894 wetness, temperature, pollutants, and other factors.

No other units of measurement astm d5894 included in this standard.
