ISO 16730-4:2013 shows how ISO 16730‑1 is applied to a calculation method for a specific example. It demonstrates how technical and users' aspects of the method are properly described in order to enable the assessment of the method in view of verification and validation. The example it gives describes the application of procedures given in ISO 16730‑1 for a structural fire resistance model. The main objective of the specific model treated here is the simulation of the heat transfer and structural responses of wall assemblies.
