Where a product is previously registered against a specification, manufacturers are required to confirm that the product remains compliant with an amended specification using the correct Form from TOPAS 0600 Appendices, in order for the product registered to be migrated on the TOPAS website. Where products are pending registration as a result of review notices, manufacturers are urged to take part in the review process

30th January 2015

The first issues of TOPAS specifications are adapted from the Highways Agency specifications TR25** Series/version that they replace. There are no changes of substance to the specifications, save that all statutory requirements have been removed from Section 1 and a new Appendix Z has been added identifying Technical File Content requirements. Manufacturers must still comply with all statutory requirements and regulations in force as at the date of production and are responsible for ensuring this. Where a TOPAS specification identifies a superseded standard or regulation, this should be read as requiring compliance with the most recent version and not the superseded one.

Any discrepancies existing in the HA specifications taken over by TOPAS will be dealt with at the next round of TOPAS specification Reviews.

This will not affect the status of any HA Type Approvals in existence or presently being requested through the HA.
