Introduction
The requirements of this part of HD 60364 supplement, modify or replace certain of the general
requirements contained in Parts 1 to 6 of HD 60364.
The clause numbering appearing after 709 refers to the corresponding parts or clauses of
HD 60364, Parts 1 to 6. Numbering of clauses does not, therefore, necessarily follow sequentially.
Numbering of figures and tables takes the number of this part followed by a sequential number.
The absence of reference to a part or a clause means that the general requirements contained in
Parts 1 to 6 of HD 60364 are applicable.
