Alber Ratman, again I feel I must say something because this is getting tedious. It is quite obvious that A and C is NOT advocating the use of our of date components. He is suggesting that, as the conditions under which a component is used change, there may be a case for the manufacturer (for example) to re-evaluate the in use life of the item. It may be that changes in conditions affect the safe life of the item.
If the manufacturer were to collect and analyse new data, they may wish to declare a different in-use life. Frankly, I doubt this will happen, especially for equipment that is no longer supported, but that is not the point.
The point is, Alber, you are clearly not reading A and C's posts and are arguing against something he's not saying. I would drop it there if I were you, you are massively disrupting the thread.
