Note 1 to entry: Pipes having more than one layer are considered as solid wall pipes, provided they are all made

from the same formulation.
3.17
virgin material

material in the form such as granules or powder that has not been subjected to use or processing other

than that required for its manufacture

Note 1 to entry: Virgin material is a material to which no own and/or external reprocessed or recycled material

has been added.

Note 2 to entry: It is understood that the addition of additives such as stabilizers and pigments is still resulting

into a virgin material.
3.18
non-virgin material
all material which is not defined as virgin material

Note 1 to entry: It covers own reprocessed material, external reprocessed materials and recycled materials.

3.18.1
own reprocessed material

material prepared from rejected unused pipes, gutters, fittings and ancillaries, including trimmings

from the production, that will be reprocessed in a manufacturer's plant after having been previously

processed by the same manufacturer by a process such as moulding or extrusion, and for which the

complete formulation is known

3.18.2
external reprocessed material

material prepared from unused thermoplastics products regardless of where those products were

manufactured

Note 1 to entry: External reprocessed material is often called post-industrial recyclate.

3.18.3
recycled material

material prepared from used thermoplastic products which have been cleaned and crushed or ground

Note 1 to entry: Recycled material is often called post-consumer recyclate.

agreed specification

specification of the relevant material characteristics agreed between the supplier of the non-virgin

material and the pipes and/or fittings manufacturer
