Note: much of this information came about several years ago,
before Adobe Acrobat (PDF) format was invented. These older
documents were scanned in jpeg, gif, or are postscript files.
This resulted in large files and/or poor image qualities (jpegs).
With the advent of Adobe Acrobat (PDF) format, the documents may
be stored on smaller files and be displayed much more clearly.
Adobe Acrobat reader is available for free. Click the following
icon to get a copy if you don't already have it. Some of these
older documents are being rescanned and/or converted into PDF
format and made available as well. The refrigerant which became
known as R-406A (GHG Refrigerant-12 Substitute back then) was
invented in August 1990.
