Hi NIST-John, Chris, IPC LF Listservers, <I saw an early prototype of the IPC Standard 1572 Declaration form. It had places for entry of values and units on the second page. Perhaps Fern Abram can verify this? I'm sure we will discuss it at the NIST Workshop Declarations Session on 10/6 because NIST is participating in the development of the 157x series of standards.> Yes It has a pull down menu where all of the (committee, company) agreed upon substances can be selected for furthur entry in other fields. The list comes intially from the JIG.
