Evaluation of the effects of standardized fuels, oils, and other liquids on rubber materials is done by ASTM D471. Weight of the rubber sample after exposure to the test liquid at specified temperatures is measured and compared with the initial weight of the sample to calculate the Weight Gain/Loss.
Scope:
The ASTM D471 test method is used for evaluating the effects of standardized fuels, oils, and other liquids on rubber materials. Applications where rubber materials are needed to withstand aggressive liquids in harsh conditions like gaskets, hoses, and seals need this test to be done. The end-user of the materials defines the relevant liquids, temperatures, and time for testing in order to satisfy the application’s specific needs in end use conditions.
Test Procedure:
For the ASTM D471 test method, weight of the samples is measured first and is recorded for weight adjustments later. The samples are then immersed in the required liquids in suitable containers; volatile liquids, such as fuels, require extra care. The containers are then put in ovens for the required time periods and temperatures. Samples are allowed to cool down to room temperature, by the end of the exposure time. After wiping the samples dry, the final weight is calculated and registered. A standard oven and mettler balance are the major equipment used for this test.
Specimen size:
The standard specimen size for weight gain/loss measurement is 25 × 50 × 2 mm
Data:
Weight change, in percentage is provided as:Weight change (%) = [(Weight (F) – Weight (I)/ Weight (I)] × 100
Weight change, in percentage is provided as:
Weight change (%) = [(Weight (F) – Weight (I)/ Weight (I)] × 100
Conclusion:
ASTM D471 test method covers the required procedures to evaluate the comparative ability of rubber and rubber-like compositions to withstand the effect of liquids.

The ASTM D2674 is a standard test method for the analysis of sulfochromate etches solution used in the surface preparation of aluminum. The ASTM D2674 standard specifies a method for determining the efficacy of an etchant used to prepare the surface of aluminum alloys for subsequent adhesive bonding.
An immunological method for quantization of Hevea Natural Rubber (HNRL) proteins using rabbit anti-HNRL serum. Rabbits immunized with HNRL proteins react to the majority of the proteins present, and their sera have the capability to detect most if not all the proteins in HNRL.
