ASTM D471 is a test method that determines the ability of rubber and rubber-like compositions to withstand the effects of liquids. ASTM D471 test method evaluates the strength of rubber products to withstand the effects of liquids. ASTM D471 test method is generally applicable to specimens of vulcanized rubber cut from standard sheets, specimens cut from fabric coated with vulcanized rubber or finished articles of commerce. ASTM D471 results utilized in quality control, research, development work, performance evaluation, and specification preparation. Read more about ASTM D412/ D471 rubber property below

Introduction to ASTM D471
ASTM D471 is a test method designed to measure the extent to which rubber products withstand the effects of liquids. It evaluates the effects of standardized fuels, oils, and other liquids on rubber materials. The specific liquids, temperatures, and times for testing for this method are decided as per the recommendations of the end user. The results obtained by ASTM D471 are specially used for quality control, research, development work, performance evaluation, and specification purposes.
ASTM D471 test method is generally applicable to specimens of vulcanized rubber cut from standard sheets, specimens cut from fabric coated with vulcanized rubber or finished articles of commerce. ASTM D471 method is not advised to be used for cellular rubbers, porous compositions, and compressed sheet packing. MaTestlab has the best network of testing labs serving in the USA.
ASTM D471 Test Method
This test method proceeds with exposing the specimens to the influence of liquids under definite conditions of temperature and time. The resulting deterioration is determined by detecting the changes in physical properties such as stress/strain properties, hardness, changes in volume, mass, and dimensions before and after immersion in the test liquid.
Test procedure for a change in mass and volume
Three specimens of a single composition are taken and the test results are computed. We average the results and weigh each specimen before immersing it in the test tube containing the test liquid. The specimen is removed from the test tube after the specified time and weighed. Firstly, weigh the test specimen with ballast in water. Then we weigh the ballast alone in the water and compare the two readings to get the final results.
Dimensional Change Test procedure for water-insoluble liquids
The dimensions of the specimens are measured and the specimens are immersed in the water-insoluble liquids. After a specified period, the specimens are removed from the immersion apparatus and cooled. Next, one has to calculate the test results and report the findings.
ASTM D471 Specimens
Specimen details
ASTM D471 includes specimens of vulcanized rubber cut from standard sheets or specimens cut from fabric coated with vulcanized rubber.
Specimen dimensions
The general sample size for ASTM D471 is 25 x 50 x 2mm (1″ x 2″ x 0.08″)
Specimen preparation
Specimens are injection molded or cut from molded or extruded sheets or plates.
ASTM D471 Results
This test method evaluates the strength of rubber products to withstand the effects of liquids. We get to record the percent change in volume, percent change in mass, percent change in dimensions, percent change in width, percent extracted soluble matter, hardness, and tensile strength of the specimen through this method. This standard helps compute the weight change expressed in percent by means of the following formula:
