ISO4925 Brake Fluid Metal Test Piece Corrosion Test Apparatus
Summary
This instrument is mainly used to test the corrosivity of brake fluid to metals.
The principle is to polish and weigh seven specified metal plates, combine them in a certain form, place them on the rubber bowl inside the test bottle, add water-containing brake fluid to submerge the test pieces, cover, and then place them in the instrument. After maintaining for 120 hours, remove and cool, then perform relevant tests on the metal plates, rubber bowl, and brake fluid according to the product standard requirements.
