There are 3 inspection methods for DEF; DEF analyzer inspection,
pH test paper inspection, and refractive index measurement
inspection. Use one method from three for inspection.
2. DEF ANALYZER INSPECTION
(1) Extract the DEF and put a few drops on the DEF analyzer to mea-
sure DEF concentration. Replace the DEF if the measurement
reading exceeds the standard value.
Standard value (%)
3. PH TEST PAPER INSPECTION
(1) Extract the DEF and put a few drops on the pH test paper to
check color change. Replace the DEF if the measurement reading
exceeds the standard value.
Concentration (%)
32.5
4. REFRACTIVE INDEX MEASUREMENT INSPECTION
(1) Extract the DEF and put a few drops on the refractometer to mea-
sure refractive index. Replace the DEF if the measurement read-
ing exceeds the standard value.
