This part of ISO 8292 specifies a direct method for the determination of solid fat content in animal andvegetable fats and oils (hereafter designated ""fats"") using low-resolution pulsed nuclear magnetic resonance (NMR) spectrometry.Two alternative thermal pre-treatments are specified: one for general purpose fats not exhibiting pronounced polymorphism and which stabilize mainly in the B*-polymorph; and one for fats similar to cocoa butter which exhibit pronounced polymorphism and stabilize in the B*-polymorph. Additional thermal pre-treatments, which may be more suitable for specific purposes, are given in an informative annex.The direct method is easy to
