Lubricating oils according to ASTM D6443 and D4927
Almost all commercial oils contain chemical additives to enhance their performance for a particular application. ASTM D6443 and ASTM D4927 international standard test methods are used to determine if the oils, additives, and additive packages meet specification. These methods employ wavelength dispersive X-ray spectroscopy (WDXRF) and mathematical matrix corrections procedures. XRF is an excellent method for multi-elemental analysis. It produces fast, cost-effective, precise and accurate data. Data can be used for quality control, product development and product performance classification. XRF provides very stable data. Thanks to the integral smart monitor program, individual calibrations can be used for months, avoiding time-consuming and costly re-standardization. Automated analysis reduces measurement times to six minutes and efficient sample preparation methods support analysis rates of ten samples per hour. User-friendly software allows routine analysis to be carried out by factory operators.
