Hi everyone,
New to this websit, I apologies in advance for posting in the wrong forum but I can’t find a CSA Code forum so if figured aws would be the next closest thing.
I have a question in regard to CSA W47.1 Figure 33 for reduced section transverse tension specimens. I am attempting to decipher note 5 especially the last sentence.
From copy and pasted from CSA W47.1 figure 33
Notes:
(1) Tp = nominal thickness of the plate.
(2) The ends of the reduced section shall not differ in width more than 0.102 mm. Also, there may be a gradual decrease
in width from the ends to the centre, but the width of either end shall not be more than 0.381 mm larger than the
width at the centre.
(3) Narrower widths (W and C) may be used when necessary. In such cases, the width of the reduced section should be as
large as the width of the material being tested permits. If the width of the material is less than W, the sides may be
parallel throughout the length of the specimen.
(4) For standard plate-type specimens, the ends of the specimen shall be symmetrical with the centreline of the reduced
section within 6.35 mm.
(5) The dimension, t, is the thickness of the specimen as provided for in the applicable material specification. The minimum
nominal thickness is 38 mm; wide specimens shall be 4.8 mm except as permitted by the product specification.
(6) n = the number of strips into which the specimen will be sliced. For plates over 38 mm thick, specimens may be cut into
approximately equal strips. Each strip shall be at least 19 mm thick. The test results of each strip shall meet the
minimum requirements.
