[MW:18461] Re: 18451] CVN Test Temperature Reduction AWS D1.1

Dear all.! Good day.!

   For the above case the test temperature would be :  -20-11.1= -31.1 deg C 

  My query is base metal thickness to be considered in temperature reduction ( code reference please )

 

  For example, if the material thickness is 7mm and specimen is 10X4mm, MDMT -20 deg C , the test temp would be..?  (-36.8 or -32.3 deg C - code reference please )

Note: ASME sec VIII Div 1,  it is clearly mentioned that the base metal thickness to be considered , Para UG 84 (c) 5 (b)

Dear Experts

 

I have question about using sub-sized specimen for CVN test

Testing temperature following specification   is -20^oc ,Plate thickness is 8mm and specimen sized is 10x5

My question How much temperature will apply for testing (AWS D1.1)

 

"4.36.7 When sub-sized specimens are required, and the

width of the specimen across the notch is less than 80%

of the base metal thickness, the test temperature shall be

reduced in conformance with Table 4.15, unless otherwise

specified in the contract documents

Thanks in advance

 

 

Tuan
