KI-19490 Dropping Point Apparatus
Test Method
Dropping point determinations are used for identification and quality control purposes, and can be an indication of the highest temperature of utility for some applications. The sample is heated at a prescribed rate in a precision machined cup whose sides slope toward an opening at its center. The temperature at which a liquid drop first falls from the cup is the dropping point of the sample.

Features and Benefits
•Conforms to ASTM D566, D4950 and related specifications
