This CP gives a description of the procedures and requirements related to documentation, design and type testing applicable for TA of carbon fibre tows.

TA is based on compliance with material requirements given in the Society's rules and/or other regulations and standards. The CP describes the applicable material requirements and how to document compliance with the requirements in order to obtain a TA certificate. This includes, where relevant, technical requirements for how the type tests shall be performed.

Scope of type approval

This type approval programme includes requirements for:

- carbon fibre tows.

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

- number of filaments

- TEX.

Deviation from the requirements may be accepted on a case-by-case basis and will be stated in the certificate.
