a) The specifications for some tapered poles have been changed (see Tables 1, 2, and 3; Tables 1, 2, 3, 4, and 5 in the.2014 edition);

b) The types of admixtures and their requirements have been expanded (see 5.1.4);

c) Added requirements for fiber raw materials (see 5.1.5);

d) Design requirements for concrete mix proportions have been added (see 5.2.1);

e) The forming requirements for the reinforcing steel cage have been increased (see 5.3.4);

f) Increased requirements for pole corrosion protection (see 5.8);

g) The design strength grade requirements for concrete have been changed (see 6.1,.2014 edition of 6.1);

h) Deflection requirements have been added for poles longer than 15m and shorter than or equal to 18m (see 6.4.1, 6.4.2, 6.4.3, and 6.4.4);

i) Increased requirements for the destructive characteristics of utility poles (see 6.4.5);

j) Added content to the marker lines (see 9.1);

k) The schematic diagram of the main segments of the tapered bar has been revised (see Figure A.1, Figure A.1 in the.2014 version);

l) The loading procedure has been changed (see B.5,.2014 version of B.5). Please note that some content in this document may involve patents.
