ASTM D543 Standard Practices for Evaluating the Resistance of Plastics to Chemical Reagents
ASTM D543 is a standard test method used to determine the resistance of plastics to chemical reagents. The test measures the effect of exposure to various chemicals on the physical and mechanical properties of the plastic material.
GET STARTED
Introduction to ASTM D543
ASTM D543 is a widely used practice for evaluating the resistance of plastics to chemical reagents. The test measures the effect of exposure to various chemicals on the physical and mechanical properties of the plastic material. The results obtained from this test can be used for quality control, material specification, and research purposes. The test generally applies to most plastics, but the specific reagents used may vary depending on the type of plastic being tested. All plastic materials including cast, hot-molded, cold-molded, laminated resinous products, and sheet materials can be evaluated for resistance to chemical reagents. ASTM D543 is used to compare the relative resistance of various plastics to chemical reagents.
ASTM D543 is a test method that determines the resistance of plastics to cracking in an accelerated environment of constant immersion in liquids. This test is essential for quality control and specification purposes, especially in industries where plastic materials are used extensively. Results of the ASTM D543 test method depend upon types and concentrations of reagents, duration of immersion or stress, or both, level of stress, temperature of the test, etc.
ASTM D543 Test Method
The test method involves exposing the plastic material to a specific chemical reagent for a specified period of time. After exposure, the material is evaluated for any physical or mechanical changes. The plastic specimens are cut to a specific size and shape as per the test requirements. The specimens are then cleaned with a solvent to remove any impurities or contaminants. The appropriate reagents are selected based on the type of plastic being tested and the specific end-use application. The test method has two variations: immersion and spot testing.
Immersion Testing Procedure
The reagents are prepared as per the test requirements. The specimens are fully immersed in the selected reagent at a specific temperature for a specific duration as per the test requirements. After the immersion period is over, the specimens are removed from the reagent and evaluated for any changes in physical or mechanical properties, such as weight loss, color change, cracking, or loss of mechanical strength.
Spot Testing Procedure
The reagents are prepared as per the test requirements and a small amount of the reagent is applied to the surface of the specimen. After the required duration, the specimen is evaluated for any changes in physical or mechanical properties, such as weight loss, color change, cracking, or loss of mechanical strength.
ASTM D543 Specimens
Specimen Details
ASTM D543 specimen size and shape vary depending on the specific test requirements. The specimens are typically prepared as per the standard dimensions, but the size and shape can be customized as per the specific application.
Specimen dimensions
The acceptable specimen size for ASTM D543 is 75mm x 25mm x 3mm (3in x 1in x 0.125in).
Specimen preparation
The test specimens for ASTM D543 are machined to a standard size and shape. The specimens used are free of any cracks, voids, or other defects that could affect the test results
ASTM D543 Results
The results of the test method are used to determine the resistance of the plastic material to the specific chemical reagent. The results are reported as the change in physical or mechanical properties of the specimen after exposure to the reagent. These changes include weight loss, color change, cracking, or loss of mechanical strength.
Tests related to ASTM D543 ASTM D543 is similar to several other standards that evaluate the resistance of plastics to chemical reagents, including ASTM D471 and ASTM D2240. ASTM D471 measures the resistance of rubber and rubber-like materials to liquids, while ASTM D2240 measures the hardness of rubber and plastics.
