Standards & Guides

It is often difficult to know exactly which British and European standards apply to your products. Therefore, the TTF have created a series of timber standards guides for the main three commodity types, together with background information to explain exactly what the standards are, why they were created, what harmonised European standards and CE marking are and how they are relevant.

 

We have now separated the Brief Guide to European Construction Standards and CE Marking which can be downloaded below.

 

As the TTF is an authorised affiliate of BSI Standards you can find links to purchase specific standards with BSI below.

 

You can either download the guide as a .pdf or purchase each listed standards by selecting from the list below. If you choose to purchase a standard you will be directed to the BSI site.
