[EngineerKG]

Hi All,

Could you please help me understand that what does ,"Range,C/F" indicate in "Table C-5 Thermal Expansion Coefficient, Nonmetals", Pg. 247 in ASME B31.3 2008.

Thanks in advance

Hi All,

I am attaching the Page extract of the code for your ready reference.
Please help me find the solution to my above query as I need to apply it in my Project soon.

Thanks

CTE for most materials changes with temperature. The reported CTE is essentially the average over the given range.

Thanks for the reply.
I have a query that if the reported CTE is average over the range, then which value should be used outside the range.

Thanks
