ISO 1874-1:2010 establishes a system of designation for polyamide (PA) thermoplastic materials, which may be used as the basis for specifications.
It covers polyamide homopolymers for moulding and extrusion based on PA 6, PA 66, PA 69, PA 610, PA 612, PA 11, PA 12, PA MXD6, PA 46, PA 1212, PA 4T, PA 6T and PA 9T and copolyamides of various compositions for moulding and extrusion.
The types of polyamide plastic are differentiated from each other by a classification system based on appropriate levels of the designatory properties
- viscosity number,
- tensile modulus of elasticity and
- presence of nucleating agent,
and on information about chemical structure, intended application, method of processing, important properties, additives, colour, fillers and reinforcing materials.
The designation system is applicable to all polyamide homopolymers and copolymers. It applies to materials ready for normal use, unmodified and modified by colorants, additives, fillers, reinforcing materials, polymer modifiers, etc.
It does not apply to monomer casting-type polyamides of PA 6 and PA 12.
