The PED (Phase Equilibria Diagrams) Editor was created by Eric Boesch for use by the PED Data Center (NIST Standard Reference Database 31) to digitize various types of phase equilibria diagrams for addition to this series as graphics files. Binary, ternary, and schematic diagrams can be digitized, and data can be extracted. The PED Editor can also be used for general graph digitization and two-dimensional scientific drawing.

System requirements

Java must be installed in order to run this program.

The Java Web Start version includes automatic updates when new versions are available. On Windows, the Java Web Start version also supports opening the program automatically when you click on PED Editor diagram files in the Windows Explorer. The Java Web Start version of the PED Editor does not run directly out of the browser, and your browser does not need to support the Java plugin.

If you do not wish to enable Java Web Start, you can still download the JAR file, locate it using the file explorer program for your operating system, and double-click to open the file.



The PED Editor is free. If you just want to run the program, either to digitize existing diagrams or create new ones in any format, you may do so without restriction.

If you wish to sell, redistribute, or modifying the PED Editor, or to embed it in a larger work, you must consult the "About" section of the program's Help menu for license restrictions. NIST does not impose any restrictions on the use of the PED Editor or its source code beyond those that are necessary to comply with the terms of the included third-party libraries.
