The construction of the gravelometer equipment for the standards ASTM/SAE is completely different when compared to standards DIN/ISO/VDA. Taking a look at the details above, you will realize that in order to make all in the same equipment, user must switch most of the components of the equipment, and furthermore, be capable of adjusting and calibrating equipment every time components are switched to avoid any leaks, if this is not accomplished correctly, it will interfere in the results of the test. In conclusion, making both ASTM/SAE and DIN/ISO/VDA in the same equipment is completely is impracticable, that’s why Equilam provides both standards in two different equipment.
