ASTM D4585 PDF

More D Failure in a condensation test may be caused by a number of factors including a deficiency in the coating itself, contamination of the substrate, or inadequate surface preparation. The test is therefore useful for evaluating coatings alone or complete coating systems. These tests usually result in a pass or fail determination but the degree of failure also may be measured. A coating system is considered to pass if there is no evidence of water-related failure after a specified period of time. However, it is possible to test the blister resistance of house coatings on wood specimens by mounting the uncoated wood surface facing the inside of the chamber.

More D Scope 1. Condensation is produced by exposing one surface of a coated specimen to a heated, saturated mixture of air and water vapor, while the reverse side of the specimen is exposed to the cooling effect of room temperature air.

This practice is derived from research of the Cleveland Society for Coatings Technology. It does not specify specimen preparation, specific test conditions, or evaluation of results. Note 1—Alternative practices for testing water resistance of coatings include Practices D, D, and D The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

Combining values from the two systems may result in non-conformance with the standard. 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.

Goltikora Link to Active This link will always route to the current Active version of the standard. Do not leave the specimens in the apparatus at the conclusion of the test as the specimens can remain wet for hours, or even days, when the apparatus is turned off. Remove only as many specimens as can be rated within the speci? The test specimens are inclined so that condensate runs off the test surface by gravity and is replaced by fresh condensate in a continuous process during the condensate cycle. Combining values from the two systems may result in non-conformance with the standard. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. The specimens should be mounted to avoid d between specimens that allow heat and moisture to escape.

This standard describes an accelerated aging test which allows to assess the water resistance of coatings through the use of controlled condensation. More specifically, this practice states the principles and the operating conditions that required to achieve consistent results from lab to lab. Moreover, ASTM D does not provide any indications regarding the preparation of the specimen, the specific test conditions, nor does it offer any guidance or requirements for the evaluation of the results.

Testing Water Resistance of coating using controlled Condensation—use and factors to consider: The purpose of ASTM D is to assess the capacity of a coating to resist deterioration that is caused by water through the use of a condensation test.
