This document specifies methods for determining the melting point and melting range of solid pesticide technical materials and their active ingredients. It details three measurement techniques: the traditional capillary tube liquid bath method, the capillary melting point apparatus method based on automatic detection via photoelectric or mechanical sensors, and differential scanning calorimetry, which provides thermal information simultaneously. Therefore, according to the standard requirements, laboratories may select corresponding methods and equipment for testing, such as liquid bath devices with precision thermometers, fully automated capillary melting point apparatuses, and differential scanning calorimeters.
