Method library / controlled references
The method is part of the answer, not the whole answer.
A crawlable reference map for common coolant and oil measurements. Matrix, product, system and decision context determine applicability.
VeriFluid maps each requested result to the question it can reasonably support. Method titles below link to their official publishers; they do not represent an accreditation claim.

Important distinction
A method code is not a universal data-center fluid specification.
Several standards originated in adjacent glycol-coolant, insulating-liquid or petroleum applications. VeriFluid uses them only where the published scope, matrix validation and declared fluid support the measurement.
