SUMMARY OF CHANGES

Committee B05 has identified the location of selected changes to this standard since the last issue
(B 169/B 169M 01) that may impact the use of this standard. (Approved Oct. 1, 2005.)

(1) For clarity, the table on mechanical properties (Tensile and under was changed from 225 to 250 MPa. Also, 12.0 to
Requirements) was broken up into two tables, Table 2 and 50.0 soft 0.2 % Offset Yield Strength was changed from 210
Table 3. Table 2 is for the inch-pound system, and Table 3 is for to 205 MPa. These values are more consistent with other
the SI system. rationalized metric values in the specification.
(2) Two rationalized metric values for C61300 were changed (3) Minor editorial changes were made throughout, which do
in Table 3. The 0.5 % Extension Yield Strength for soft 12.0 not impact the usage of this standard.
