GB/T 6843-1986
Method for determining the coating melting point of photographic materials

This standard specifies a test method for determining the melting point of coatings on silver halide photographic materials, such as film, plates, and photographic paper. The applicable coatings include emulsion layers as well as gelatin or resin coatings, but it explicitly excludes non-silver halide photographic materials. According to the standard requirements, traditional determination may involve instruments such as capillary melting point apparatus. Currently, modern laboratories often employ more advanced automated equipment for this test, such as fully automated image melting point instruments equipped with high-resolution cameras, which enable visual recording and precise analysis of the sample's melting process. Additionally, sophisticated thermal analysis instruments like differential scanning calorimeters are commonly used in such studies to obtain more comprehensive thermal performance data.
