This Code of Practice has undergone a full revision. Prescription that provided a barrier to product innovation and adoption of the code by VSS installers has been removed, requirements for two types of system are contained within the code, some clauses have been rephr ased to add clarity and some requirements within clauses have been moved to more appropriate clauses. The key changes to the Code of Practice includes: • t he simplification of the technical requirements of the standard with the introduction of a tiered appro ach as follows: o Type A (base recommendations); o Type A+ (enhanced recommen dations for higher risk sites). • the removal of the RVRC (ARC) recommendations as these have been moved to another standard (BS 9518).
