1.3 What should be specified in the detailed specification
1.3.1 General
The detailed specifications shall be compiled in accordance with the relevant blank detailed specifications.
The detail specification shall not specify requirements lower than the general specification, sub-specification or blank detail specification. When it contains more than the general specification, sub-specification, blank
When the strict requirements of the detailed specification are specified, they should be listed in the corresponding clauses of the detailed specification and pointed out in the test list, for example, marked with an asterisk.
For convenience, the information given in 1.3.2 and 1.3.4 should appear in the form of a table.
