A mapped index of the ASTM, ISO, TAPPI, AATCC, IPC, IEC, EN, API, USP and other standards relevant to contact angle, surface tension, surface energy and wettability with an honest statement of how Dropometer relates to each. Each standard links to a dedicated page explaining what it specifies, how the measurement is performed, and exactly where Dropometer fits its workflow. Compliance tier reflects measurement equivalence, not a formal accreditation claim.
