Scope

This standard specifies a method for determining the content of various metal elements in unused grease using inductively coupled plasma optical emis ion spectroscopy (ICP-AES). Metal elements include aluminum, antimony, barium, calcium, iron, lithium, magnesium, Molybdenum, silicon, sodium and zinc can also be used for the determination of phosphorus and sulfur non-metallic elements. The measurement range of this standard is aluminum (10mg/kg ~ 600mg/kg), antimony (10mg/kg ~ 2300mg/kg), barium (50mg/kg ~ 800mg/kg), calcium (20mg/kg ~ 50000mg/kg) , Iron (10mg/kg ~ 360mg/kg), lithium (300mg/kg ~ 3200mg/kg), magnesium (30mg/kg ~ 10000mg/kg), molybdenum (50mg/kg ~ 22000mg/kg), phosphorus (50mg/kg ~ 2000mg/kg), silicon (10mg/kg ~ 15000mg/kg), sodium (30mg/kg ~ 1500mg/kg), sulfur (1600mg/kg ~ 28000mg/kg) and zinc (300mg/kg ~ 2200mg/kg). Elements whose content is lower than this range can be measured by increasing the sample amount. Elements whose content is higher than this range can be measured by reducing the sample amount, or increasing the dilution factor after dis olving the sample. However, the precis on under these conditions has not been determined and may differ from that given in Table 3. This standard can also be used for the determination of other metals, such as bis uth, boron, cadmium, chromium, copper, lead, manganese, potassium, titanium, etc. However, there is not enough data to determine its precis on. These metals can be considered as impurities or added elements in the grease. In preparing specimens, grease samples are decomposed using various acids (and their mixtures). This standard does not specify specific acid types. If the ash dis olves and produces insoluble matter vis ble to the naked eye (assuming that the insoluble matter contains part of the element to be measured
