ISO BLACK TEA SPECIFICATION - ISO 3720 1977 (First edition)
"INTRODUCTION
The content of CAFFEINE and the content of POLYPHENOLIC constituents are
important chemical characteristics of black tea, but it has not been possible to
include limits for either of them in the specification. In the case of CAFFEINE,
agreement has not yet been reached on a standard method for the determination.
In the case of POLYPHENOLIC CONSTITUENTS, knowledge about
test methods is not sufficiently developed to justify the standardization of any one
of the methods in existence; moreover, information on the content of these
constituents is only available for a few types of tea."
