Overview

EN ISO 16396-1:2022 - Plastics - Polyamide (PA) moulding and extrusion materials - Part 1: Designation system and basis for specifications (ISO 16396-1:2022) is a CEN-adopted international standard that defines a systematic method to designate polyamide (PA) materials. It provides a structured identity and data-block format for describing PA homopolymers, copolymers and blends used for moulding and extrusion. The standard is intended as the basis for material specifications but does not supply engineering performance data or processing conditions.

Key topics and requirements

• Designation system structure: A standardized identity block and an individual-item block subdivided into five data blocks. The first character of the individual-item block is a hyphen; data blocks are separated by commas. Omitted data blocks are shown by consecutive commas.
• Data block content (summary):
  • Data block 1: Polymer identification (PA per ISO 1043-1) and composition, plus use of plasticizers or impact modifiers.
  • Data block 2: Fillers/reinforcements, nominal content, flame retardant info and recyclate declaration.
  • Data block 3: Intended application and/or processing method; important properties, additives and supplementary information.
  • Data block 4: Designatory properties - the classification basis: viscosity number, tensile modulus, and nucleating additive.
  • Data block 5 (optional): Additional requirements for a formal specification (e.g., property limits, test requirements).
• Scope and applicability: Applies to unmodified and modified PAs (colorants, additives, fillers, reinforcements, polymer modifiers) but excludes monomer casting‑type PA 6 and PA 12.
• Limitations: The same designation is not a guarantee of identical performance across suppliers; engineering and processing data are not provided. Test methods for additional properties are referenced in ISO 16396-2.

Practical applications and users

• Useful for:
  • Material manufacturers and suppliers for consistent labelling and datasheet formatting.
  • OEMs, designers and engineers who need a standardized material identity for procurement and design communication.
  • Procurement and quality teams specifying polyamide grades in contracts and specifications.
  • Test laboratories and standards committees aligning test reporting with designation blocks.
• Benefits:
  • Streamlines material identification, comparison and documentation.
  • Supports traceability when combined with test results or property limits in Data Block 5.
  • Facilitates regulatory and recycling information capture (e.g., recyclate declaration).
