Thanks all for trying to help.
The standard is fairly clear on what the letters stand for, what is not so clear is whether or not the letter s has to precede the penetration dimension when one is used (no dimension implies full penetration.
Thanks for the reply Rick, a valid point about the compressibility of the plastic. But the point I'm having problems with is what effect does pressure have on the water absorption.
I found this old thread that relates to my problem but unfortunately it never got answered.

I'm fairly sure that the % volumetric change of a component isn't the same as the % water absorption but I assume there must be some relationship even if it's material specific. I would be...
Can anyone tell me if the letter "s" is required before the dimension for weld penetration on anything other than fillet welds? I can see from the standard that an "a" or a "z" is required when specifying fillet weld size but the examples for other welds are unclear as to the requirement for the...

I'm thinking of using Oilon plastic as a bearing material in a subsea application but can't find any consistent information on its' water absorbtion rate. Data sheets I've found on line have values ranging from 0% to 6.2%, does anyone have reliable information as to what the rate actually is...
Marty, you're right I mis-read the table, had a closer look now and I see the issue.
Stefano, Having had a quick look at a few suppliers and they're all quoting a minimum yield of 345 MPa (or 50ksi). Common practice here is to write your own material specifications that generally copy the...
I have heard of Simulation 2010 randomly loosing applied pressures this could cause the imbalance.
Can you split the submarine on any symmetry planes? You can then effectively prevent movement perpendicular to the plane with the added benefit of reducing the run time.
