ASTM D7804 is used to determine the number of releasable fibers transferred from a paint roller cover to a surface being painted. This method is applicable to pile fabric paint roller covers. The SI units should be considered as standard.
Scope:
ASTM D7804 is only used for comparative testing using one operator for each set of applications. Fibers that are released during painting can lead to a finish that is aesthetically unacceptable.
Test Procedure:
In test method D7804, the paint roller cover that is to be evaluated is used to paint a section of sealed test paper. After the paint film has dried, the fibers are counted.
Specimen size:
In ASTM D7804, three identical paint covers of 9 by 1.5 inches diameter core are used.
Data:
The results suggest that if the same person does not complete each test, the precision of this test procedure may be unstable. It is not possible to paint the same cover more than once.

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.
