ISO 1133 is a standard for determining the melt flow rate of thermoplastic materials. It is used to control the quality of polymer granules, including polystyrene, polyethylene, polypropylene, ABS, and other thermoplastics. The standard defines two parameters: volumetric and mass flow rate of the melt.
ISO 527 is a standard that specifies a tensile test method for plastics. It is used to determine the deformation, strength, and elastic properties of polymers, including polypropylene, ABS, polyamides, polyethylene, PEEK, and other thermoplastics. The standard is used to assess the quality of profiles, pipes, polymer granules, and sheets.

DIN 8077 is a standard that establishes requirements for the dimensions, tolerances, and weights of polypropylene pipes. This standard applies to polypropylene pipes and is one of the fundamental documents for the production and design of polypropylene pipelines. It defines product markings, pipe weights, design dimensions, dimensional tolerances, wall thicknesses, and pipe outside diameters.
Polypropylene welding rod standards:
DVS 2207-11 - Hot-Tool Welding of Thermoplastics for Polypropylene Pipes, Pipe Fittings, and Sheets. This technical directive establishes requirements for hot-tool welding of polypropylene products.

ISO 1873-1 is a standard establishing a classification and designation system for polypropylene materials intended for injection molding and extrusion. This standard serves as the basis for material data sheets, technical specifications, and raw material selection for the manufacture of polypropylene products. This standard allows for the standardization of material data sheets, the development of raw material specifications, the selection of materials for specific operating conditions, the comparison of materials from different manufacturers, and the classification of polypropylene grades.
Polypropylene sheet standards:
ISO 1873-1 - Designation and classification of polypropylene. This standard defines the main performance characteristics, modifiers, fillers, material structure, and polymer type. It regulates additives, melt flow index, density, processing method, and material type.
ISO 527 - Tensile testing of plastics. This standard defines the mechanical properties of polypropylene sheets. The defined characteristics include yield stress, elongation, modulus of elasticity, and tensile strength. It is used for load calculations, selection of structural thickness, and sheet quality control.
ISO 178 — bending test. Determines the sheet's ability to resist bending. This standard is used to monitor flexural strength, flexural modulus, deformation resistance, and material rigidity. For polypropylene sheets used in chemical baths, tanks, ventilation, and welded structures, this standard is a key quality indicator.
Polypropylene rod standards:
ISO 527 is a standard that defines the method for determining the tensile mechanical properties of plastics. For polypropylene sheets, rods, pipes, and other products, this standard is used to evaluate the stiffness, strength, and deformability of the material. It defines measurement methods for stress at a given elongation, yield strength, elongation at break, tensile modulus, and ultimate tensile strength.
ISO 178 - standard specifies a method for determining the mechanical properties of plastics under three-point bending. For polypropylene rods, structural components, plates, and sheets, it is used to evaluate stiffness, deformation resistance, and strength. The standard specifies the flexural modulus, deformation, stress, and flexural strength.
ISO 1133 - determination of the melt flow index of plastics. It indicates how easily molten plastic flows at a given temperature and load. For polypropylene rods, this index allows for the evaluation of batch-to-batch variations, melt flowability, production stability, and material suitability for extrusion.
