ASTM D1654 Evaluation of Painted or Coated Specimens Subjected to Corrosive Environments
ASTM D1654 is a test method that evaluates the paints and coated specimens when exposed to corrosive environments. The test is commonly used to compare the performance of different coatings or to assess the quality and durability of coatings in different applications.
GET STARTED
Introduction to ASTM D1654
ASTM D1654 is a standard test method that measures the corrosion resistance of coatings on metallic substrates. The test determines the ability of a coating to resist corrosion in a salt spray or fog environment. This method is commonly used in various industries, such as automotive, aerospace, and construction, to assess the quality and durability of coatings.
Corrosion is a natural process that can cause significant damage to metallic substrates. A coating is applied to metallic surfaces to protect against corrosion, but the effectiveness of the coating can vary depending on various factors, such as the environment and application method. ASTM D1654 provides a standardized method for determining the corrosion resistance of coatings on metallic substrates.
ASTM D1654 Test Method
The test method ASTM D1654 involves exposing coated metallic samples to a salt spray or fog environment for a set period of time. The method proceeds by placing the sample in to the chamber, exposing it to moisture and then checking it for any signs of corrosion as follows:
Sample placement
The samples are placed in a chamber where they are subjected to a continuous cycle of salt spray or fog followed by drying. This cycle is repeated for a specified duration, typically 24 to 200 hours, depending on the type of coating and the application requirements.
Checking for Corrosion Resistance
After exposure, the samples are examined for any signs of corrosion, such as rust or blistering. The severity and extent of corrosion are evaluated based on a standardized rating scale, such as ASTM D610 or ASTM D714, depending on the specific requirements of the application.
ASTM D1654 Specimens
Specimen details
The specimen used in the ASTM D1654 test method is a coated metallic sample. The sample is typically in the form of a panel or sheet and is prepared by applying a coating material to a metallic substrate.
Specimen dimensions
The acceptable specimen size for ASTM D1654 is typically a panel or sheet with dimensions of at least 10 cm x 15 cm (4 in x 6 in) and a thickness of at least 0.3 mm (0.012 inches).
Specimen preparation
Specimens are prepared by applying the coating material to the metallic substrate using a specified application method, such as spray or brush. The coating thickness and application method are specified by the test requirements.
ASTM D1654 Results
The results of the ASTM D1654 test method are reported as the appearance of the coated metallic sample after exposure to the salt spray or fog environment. The severity and extent of corrosion are evaluated based on a standardized rating scale. The results of the test are used to evaluate the effectiveness of the coating in protecting the metallic substrate against corrosion.
Tests related to ASTM D1654
ASTM D1654 is related to several other ASTM standards that measure the properties and performance of coatings on metallic substrates. These standards include ASTM D610 for evaluating the degree of rusting on painted steel surfaces and ASTM D5590 for measuring the resistance of coatings to fungal defacement.
