IEC 61182-10:1999 pdf download – Printed boards – Electronic data description and transfer – Part 10: Electronic data hierarchy.
This part of IEC 61182 specifies data file formats used to describe printed board and printed board assembly products in sufficient detail for tooling, manufacturing, assembly, and testing requirements. These formats may be used for transmitting information between a printed board designer and a manufacturing or assembly facility. The files are also useful when the manufacturing cycle includes computer-aided processes and numerically controlled machines.
The information can be used for both manual and digital interpretation. The data may be defined in either English or SI units.

For the purposes of this part of IEC 61182 and. unless otherwise specified herein, terms and definitions shalt be In accordance with IEC 60050(541) and the definitions in the following subclauses.
3.1
filename extension
three.ietter acronym used to identify a category file name
3.2
data hierarchy
organized arrangement of data, according to a specific set of rules
3.3

4 General requirements
The EDH specifies data tiles specifically for the information interchange of data relating to printed board CAD designs that have been completed and are ready for manufacturing expansion (ie. panelization, process allowance incorporation, tooling feature addition, etc.).
EDH is comprised of ten category files shown in tables 1 and 2. Figure 1 shows the relationship of the ten (10) category files and the communication links that must be established between the tiles.
Each category tile has a specific function or task and Is Independent of the other. Accordingly. the information interchange for a specific purpose is possible only if the category files required for such a purpose have been prepared. Any data file with a format different trom this lormat can be Interchanged as a non•standard category file, If the format has been mutually agreed to by the sending CAD and the receiving CAM workstation.
4.1 Category classification
Table I provides the name and purpose of each of the ten files.
