RBOT TESTING DATA PROCEDURE

CMP contracted with an independent testing laboratory to perform modified RBOT tests ASTM procedure D-2272 to determine the oxidative stability of each lubricant tested to give you the customers an idea of the quality comparison of competitive products and help you choose the best product.

This procedure employs a method to achieve rapid oxidation of the lubricant tested and measure the total minutes to destruction, the change in viscosity at 40° C. and the increase in acid number in the oil layer.

Using this method you can evaluate and compare the oxidation resistance and degradation characteristics of the oils tested and how they may perform in your vacuum pump.

As a vacuum pump oil degrades it will fail to properly lubricate the pump causing more wear on the internal pump components and loss in vapor pressure capabilitiy.

We have listed this RBOT test data on standard products like our CMP 19 and on our new Premier line of semi-synthetic vacuum pump fluids compared to competitive products on the specification pages in this catalog beginning with our new CMP MAXVAC vacuum pump fluid.

The results of these tests show our products to be clearly superior!
