[PSUBS-MAILIST] Windows

Jon,
I don't know about the ABS rules, but the acrylic bible has more to say about it.  You can extend the service  life by decreasing the rating based on age and I believe location and method of storage.

As far as ABS is concerned I suspect ABS guidelines are the
      official word on it; 10 years or 10,000 cycles.  GL has similar
      limits and adds "...regardless of the use in the submersible."

A question for the experts. Is it acceptable to have old windows re-polished and then possibly annealed to restore them.  I have 8 that are 25 years old and need to be replaced according to ABS etc. 
What is the official word on this.  I note that the windows below were from an MBT rather than main windows.   Chs  Hugh
