Overview
ISO 11403-1:2021 - Plastics - Acquisition and presentation of comparable multipoint data - Part 1: Mechanical properties - defines standardized test procedures and presentation requirements for acquiring multipoint mechanical data on plastics. It specifies how to measure and report properties such as dynamic modulus, tensile behaviour, creep, and impact performance so data from different sources are comparable and useful for material selection, modelling and engineering decisions.
Key topics and technical requirements
- Scope of properties covered
- Dynamic modulus
- Tensile properties at constant test speed (including ultimate stress and strain, and tensile stress‑strain curves)
- Tensile creep
- Charpy impact strength
- Puncture impact behaviour
- Specimen preparation
- Use injection- or compression‑moulded specimens or machined sheets prepared to recognized dimensions.
- Adopt moulding procedures in the relevant ISO moulding standards when available (e.g., ISO 293, ISO 294‑1/3, ISO 295, ISO 10724 series).
- Record moulding parameters where standards do not specify them.
- Conditioning
- Default conditioning: (28 ± 2) days at (23 ± 2) °C and (50 ± 10) % relative humidity, unless material standards specify otherwise.
- Special conditioning for moisture‑sensitive or dry‑state data is addressed and must be recorded.
- Test execution and presentation
- Prescribes test methods and conditions (where applicable) and guidance for selecting conditions that capture the polymer’s operating range.
- Requires consistent reporting of test variables, specimen history and presentation of multipoint data so trends versus time, temperature or other variables are clear.
- Precision and comparability
- Includes requirements for data presentation and references to precision assessment; enables meaningful comparisons across materials and suppliers.
Applications and practical value
- Material selection and comparison for product design
- Supplier data sheets and standardized data exchange for CAD/PLM systems
- Performance prediction and processing optimisation (moulding parameters)
- Quality control and benchmarking in test laboratories
- Development of property databases and computational material models
Who should use this standard
- Plastics material suppliers producing comparative property data
- Test laboratories and QA teams performing mechanical testing
- Product designers and materials engineers selecting plastics for components
- Data modelers building material property databases or digital libraries
