plumbing applications—General (Iso 21003-1:2008, MoD).

3.4 Definitions related to materials

3.4.1

virgin material

material, in a form such as granules or powder, that has not been subjected to use or processing other than that required for its

manufacture and to which no reprocessable or recyclable material has been added

3.4.2

own reprocessable material

single material prepared from rejected unused pipes and fittings, including trimmings from the production of pipes and fittings,

that will be reprocessed in a manufacturers plant after having been previously processed by the same manufacturer by a method such as moulding or extrusion and for which the complete formulation is known

3.4.3

reference product standard

International Standard or draft International Standard, prepared by ISOITC 1381SC 2, applicable to nonmultilayer pipes, to which

this International Standard can refer for clauses related to the materials, components (e.g. fittings) and fitness for purpose of

the system

3.4.4

stress-designed polymeric layer

polymeric layer which is designed to be stress-bearing

NOTE The materi used in such layers is restricted to those in the reference product standards (see Annex A).

3.5 Definitions related to material characteristics

3.5.1

application class

class related to a typical field of application and a design period of 50 years.
