Technical data
Requirements and reported values, separated.
“Requirement” is the stated acceptance threshold or range. “Actual result”, “typical value” and “published value” are not guaranteed minima unless the requirement column says so. Final acceptance must follow the approved TDS, report, test method and project conditions.
