[MW:31011] Re: Impact subsize specimen thickness

Dear Mr. Abhishek, 

you can  take sub size specimen provided the specimen size shall not fall below 80% the actual thickness of test coupon . i.e if you are taking specimen against each welding process involved shall not be below 80% of weld deposit @ Test temperature 

if you are not able to take specimen within 80% of test coupon or each weld deposit , you need to apply temperature reduction as per code for size of the specimen you have taken

Dear Experts,

As per ASTM A370 below thickness subsize impact  specimen mentioned are:

10 x 7.5, 10 x 6.7, 10 x 5, 10 x 3.3, 10 x 2.5

Now my question are, if I am taking a sample size of 10 x 4.5. Is it acceptable?
