A type approval certificate will be valid for one type of tow of the current product with the possibility to include variants.

Type: e.g. HT (High Tenacity) or HM (High Modulus) fibre with a specified sizing.

Variant: Fibre with different tex and/or different number of filaments.

As a minimum, the following information/properties will be printed in the type approval certificate:

— type of fibre

— type of sizing

— matrix compatibility

— with or without twist
