JJF 2099-2024 《Calibration Specification for Optical Contact Angle Measuring Instruments》 Related products

JJF 2099-2024 "Specification for Optical inspection Contact Angle Meter calibrating" is applicable to the calibrating work of Optical inspection Contact Angle Meter. This specification refers to the documents of JJF 1059.1 on the evaluation and representation of measurement uncertainty and JJF 1071-2010 on the rules for the preparation of national measurement calibrating specifications. The terminology section defines the static definition of the contact angle, that is, the angle theta between the tangent line of the gas-liquid interface and the solid-liquid boundary line at the gas-liquid-solid three-phase junction. The specification ensures the accuracy and comparability of measurement results. The latest standards and methods are adopted to meet the needs of contact angle Measurement accuracy in different application scenarios.
