Revised Standard from Last Update.

1. SCOPE

1.1 This standard prescribes the requirements, method of sampling and test for polyamide 6 resins and unfilled/filled compounds for moulding and extrusion.

1.2 This standard does not apply to polyamide 6 prepared through monomer casting that is anionic polymerization of caprolactam.

1.3 This standard does not apply to polyamide 6 prepared for textile fibre spinning.

1.4 This standard does not cover pigmented or coloured polyamide 6 resin and unfilled/filled compound.

NOTE - As properties of pigmented or coloured polyamide 6 resin and unfilled/filled compound can widely differ from respective natural colour polymer-based materials depending on the choice of colorants and concentrations, all such properties, test methods and specifications need to be agreed between purchaser and supplier.

1.5 This standard does not cover recycled/reprocessed polyamide 6 based resin and unfilled/filled compound.

NOTE - As properties of recycled/reprocessed polyamide 6 based resin and unfilled/filled compound can widely differ from respective virgin polymer-based material depending on type and content of recycled/reprocessed polyamide 6 used, all such properties, test methods and specifications need to be agreed between purchaser and supplier.

1.6 The properties and respective specifications included in this standard are those required in resin and unfilled/filled compound for different applications. However, there may be other specific characteristics important for specialized application. Selection of such specific characteristics, their evaluation and acceptance are left to expertise of the user as practically it is not possible to cover all such characteristics in this standard.

1.7 The resin and unfilled/filled compound specific properties and specifications included in this standard are intended to provide a means of calling out different polyamide 6 materials used in the fabrication of various items or parts. Accordingly, the selected material needs to qualify for respective quality criteria laid down in this standard. However, the properties of material may neither predict nor correlate with entire performance of parts moulded of the material.

Caution - This standard does not purport to address the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practises and determine the applicability of regulatory limitations prior to use.
