This document specifies the methods of preparation of test specimens and the test methods to be used in determining the properties of polyamide moulding and extrusion materials. It gives the requirements for handling test material and for conditioning both the test material before moulding and the specimens before testing. This document specifies procedures and conditions for the preparation of test specimens and procedures for measuring properties of the materials from which these specimens are made are given. It lists the properties and test methods that are suitable and necessary to characterize polyamide moulding and extrusion materials. The properties have been selected from the general test methods in ISO 10350‑1. Other test methods in wide use for, or of particular significance to, these moulding and extrusion materials are also included in this document, as are the designatory properties viscosity number and tensile modulus given in ISO 16396‑1.
Abstract
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
