SIST EN ISO 16396-2:2022 PDF

Overview

EN ISO 16396-2:2022 - Plastics - Polyamide (PA) moulding and extrusion materials - Part 2: Preparation of test specimens and determination of properties - specifies standardized procedures for preparing test specimens and measuring the properties of polyamide (PA) moulding and extrusion materials. Published by CEN and identical to ISO 16396-2:2022, this document sets requirements for handling feedstock, conditioning materials and specimens, and selecting appropriate test methods to characterize PA materials for specification, quality control and material data sheets.

Key Topics and Requirements

• Specimen preparation methods
  • Injection moulding in accordance with ISO 294-1 and consistent processing conditions to ensure comparable data.
  • Laser sintering specimen preparation (requirements and procedures referenced, including Annex A).
• Material treatment and moisture control
  • Material must reach room temperature before processing.
  • Maximum moisture content limits before processing: ≤ 2 g/kg for PAs with viscosity number ≤ 200 ml/g; ≤ 1 g/kg for PAs with viscosity number > 200 ml/g.
  • Specific PAs (e.g., PA46, PA6T/66 and certain polyamide blends) require moisture content
