Review of Significant Changes to EN 1263-1 2002

Scope has been changed to limit the performance requirements of the mechanical properties within a specific temperature range, -10⁰C to +40⁰C.

Definitions have been extended to include a symbol table to ease understanding, and some definitions have been slightly changed. E.g. Test Rope is now called Test Mesh, and definitions are included for System and Class.

Classification of the various nets and net systems has been changed to avoid the repeated use of the word “Type.”The four energy absorption classifications have been named "Class" (Class A1, A2, B1, and B2), and the various application arrangements have been named “System.”(System S, T, U, and V). A number of additional specific rope classifications have been added. In the normal UK context the most significant of these is the addition of Rope Z, at 15kN minimum tensile breaking force which is permitted for System S nets when it is independently doubled to the net edge. This idea was introduced from Germany where they like to remotely cut ties from below. Concerns were raised about the reduced abrasion resistance and reduced factor of safety of the lower capacity ties.

Select a further statistically representative sample of attachment devices. Fit to the base material for its intended use as before, however all "location only" attachments must be left open. Apply a dynamic drop test as specified in latest version of BS EN 795 for Class A2 anchors directly to the attachment device.

Temporary or permanent deformation is permitted, however the device must not release the load.

Instructions for use and limitations must include the following:

Notes:
The characteristic load is 6kN, multiple to be applied is 4, and statistical sample is 5.
