The construction of the Gravelometer equipment for the standards ASTM/SAE is completely
different when comparing 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.
