Methods of test for rigid cellular materials - Method 14. Determination of flexural properties Ingestion-build-111333 ISO/IEC 7812-1 specifies a numberingWhat is BS 4370 4 Methods of test for Rigid cellular materials about? BS 4370 4 is the fourth part of the multi series standard that describes a method to determine the modulus of elasticity and strength in flexure of rigid cellular material of polymeric origin, but it is not necessarily suitable for rigid cellular material of inorganic origin. Where a fracture occurs in the lower surface of the specimen at a low tensile strain, i. e. less than 5 %
