requirements to EN ISO 9001:2008 [1].
6 Testing and inspection
6.1 Material specification PVC
For the purposes of this Technical Specification, the material specification consists of a formulation which defines
PVC resin and additives and their dosage levels.
The dosage level of ingredients of a material shall not exceed the tolerance bands given in Table 1. If any level
exceeds the dosage band or if a type is changed, this variation in formulation constitutes a change in material.
The use of reprocessable and/or recyclable material with agreed specification shall be considered as a change in
formulation when the change in addition exceeds the tolerance bands given in Table 2.
The values of the parts X added to 100 parts by mass of PVC shall be specified by the manufacturer in his quality
plan.

6.2 Material specifications PP
For the purposes of this Technical Specification, the material specification consists of a compound comprising a PP
compound with specific trade name and additives with specified dosage level.
When a masterbatch is used, it shall be considered as a change of compound, if the type of carrier of the pigment is
changed.
In case the content of the mineral modifier by mass is higher than the measured content by mass at the Type testing
or a new type of mineral modifier is used, the compound shall be considered as a new material.

The use of reprocessable and/or recyclable material with the agreed specification shall be considered as a change in
compound when the change in addition exceeds the tolerance bands given in Table 3.
