ISO 28941-1:2008 establishes a system of designation for PPE thermoplastic materials, which may be used as the basis for specifications.
The types of PPE plastic are differentiated from each other by a classification system based on appropriate levels of the designatory properties
temperature of deflection under load
melt volume-flow rate
Charpy notched impact strength
flammability
and on information about basic polymer parameters, intended application and/or method of processing, important properties, additives, colorants, fillers and reinforcing materials.
ISO 28941-1 is applicable to all PPE materials, including those modified with polystyrene or polyamide or other materials.
It applies to materials ready for normal use in the form of powder, granules or pellets and to materials unmodified or modified by colorants, additives, fillers, etc.
