Often, on returning home from one of those mysterious and prolonged absences that gave rise to such strange conjecture among those who were his friends, or thought that they were so, he himself would creep upstairs to the locked room, open the door with the key that never left him now, and stand, with a mirror, in front of the portrait that Basil Hallward had painted of him, looking now at the evil and aging
face on the canvas, and now at the fair young face that laughed back at him from the polished glass.
Short term fluid agings in ASTM #3 oil, Ford and GM engine oil, and Ford and GM automatic transmission fluid for the four AEM types are shown in figure 2.
The extended agings carried out for this article have shown some very interesting trends.
Extended aging studies in both engine oil and automatic transmission fluid will be used to demonstrate the merits of AEM polymers over the long term for powertrain gaskets.
A materials engineer from General Motors, John Beckett, was interested in being able to use short term, high temperature agings to forecast rubber part life.
The data showed that the property changes based on this aging at simulated service temperatures correlated well with end product performance.
