ISO 10350-1:2017

Overview

ISO 10350-1:2017 - Plastics - Acquisition and presentation of comparable single-point data - Part 1: Moulding materials - defines a standardized way to acquire and present single-point material data for moulding plastics. The standard focuses on comparable, single-value properties commonly shown on manufacturers’ data sheets for unreinforced and reinforced thermoplastic and thermosetting materials that are injection- or compression-moulded or prepared as sheets. It clarifies specimen preparation, conditioning, test requirements and the prescribed format for reporting results so that material comparisons are meaningful and reproducible.

Key topics and requirements

• Single-point data scope: Specifies which basic properties should be expressed as single experimental values (or, where applicable, two values under different conditions) for preliminary material selection.
• Material coverage: Applies predominantly to moulding materials (thermoplastics and thermosets). Long-fibre-reinforced plastics are defined as having fibre lengths > 7.5 mm prior to moulding (ISO 10350-2 covers long/continuous fibres).
• Specimen preparation: Requires use of established moulding or machining procedures (e.g., ISO 294-series for injection moulding, ISO 293/295 for compression moulding, ISO 2818 for machining).
• Conditioning rules: For materials insensitive to absorbed water, condition specimens at 23 °C ± 2 °C and 50 % RH ± 10 % for ≥ 88 h (unless a material-specific standard applies). For water-sensitive materials, present data for both dry and 50 % RH conditions with specified exceptions. Store conditioned specimens at 23 °C ± 2 °C for ≥ 16 h before testing.
• Test methods and presentation: The standard prescribes the test methods, conditions, units and a table format for presentation (e.g., rheological properties such as MFR use ISO 1133). Report mean values and record moulding parameters and sample provenance; testing on specimens from at least three production samples is recommended.

Practical applications and users

ISO 10350-1 is intended for:

• Material suppliers preparing standardized data sheets
• Design and product engineers comparing candidate plastics during early-stage selection
• Quality and testing laboratories ensuring reproducible single-point test data
• Procurement/specification writers requiring comparable property data across suppliers

Typical uses include preliminary material selection, supplier comparison, formulation screening and generating consistent technical data for product datasheets.
