ISO Standards

---

The International Organization for Standardization (ISO) develops globally recognized standards to ensure quality, safety, and efficiency across various industries. In the context of injection molding, ISO standards provide precise guidelines for producing and testing plastic specimens, ensuring consistency and reliability in material evaluation. Adherence to these standards is crucial for manufacturers aiming to validate material properties, meet regulatory requirements, and maintain product integrity.

This standard specifies methods for determining the tensile properties of plastics, including tensile strength, modulus of elasticity, and elongation at break. It is essential for assessing a material's behavior under tensile stress. ​

ISO 178 outlines the procedure for measuring the flexural properties of rigid and semi-rigid plastics. It involves a three-point bending test to determine flexural strength and modulus. ​

This standard describes the method for assessing the impact resistance of plastics using the Charpy impact test. It measures the energy absorbed by a specimen during fracture. ​

ISO 604 specifies a method for determining the compressive properties of plastics, including compressive strength and modulus. It is vital for applications where materials are subjected to compressive forces.

This standard provides procedures for measuring the flow rates of thermoplastic materials under specified conditions, which is crucial for understanding processing behavior. ​

ISO 75 outlines the method for determining the temperature at which a plastic specimen deforms under a specified load, indicating its heat resistance. ​

This standard specifies the dimensions and types of test specimens used for various mechanical property tests, ensuring consistency across different testing methods. ​

ISO 294 provides guidelines for the preparation of test specimens through injection molding, detailing the molding conditions and specimen dimensions required for accurate testing. ​
