Currently reading a scientific paper, I have trouble understanding the use of
保証.

An example of its use is the following:

最低保証密度として75%を乗じる (remarks about the percentage of a certain element in a
mixture, the usual percentage is around 10%)

I know the kanji should mean "guarantee" so I was thinking about "found in the
literature", "peer validated" or something along those lines.

What is 保証 used for in this context?

question
words usage
What does 保証 mean in this context?
保証 usually is a guarantee/warranty made by a manufacturer, government, etc.
Scientific knowledge from previous research is rarely considered as 保証 if
there is no further context.

The literal translation of 最低保証密度 is "lowest guaranteed density." It seems to
say that if the density is below 75%, something (e.g., chemical reaction) is
not guaranteed (usually by the manufacturer, etc.) to happen.

I don't know why something is multiplied by 75%, because there's no context.
