Required sized of steel coupon taken from existing beam or column?

Required sized of steel coupon taken from existing beam or column?

Required sized of steel coupon taken from existing beam or column?

(OP)
Is there a standard size in taking steel coupons from existing steel members for purposes of determining the tensile strength?

RE: Required sized of steel coupon taken from existing beam or column?

I have typically used in the past, 12" long by 2" wide if possible. If not, 8" long x 1-1/2" wide. Either will allow preparation for a reduced section tensile test where the gauge length will be at least 2". Check ASTM A8 for specifics of coupon testing.

RE: Required sized of steel coupon taken from existing beam or column?

(OP)
I didn't realize the length dimension would need to be that large. Can you get by with less?

I'll try to round up a copy of ASTM A8.

RE: Required sized of steel coupon taken from existing beam or column?

(OP)
Looks like it must actually be E8, not A8.

RE: Required sized of steel coupon taken from existing beam or column?

(OP)
Or maybe A370?

RE: Required sized of steel coupon taken from existing beam or column?

abp...my apologies...it is E8
