3. Subject to regular inspection for soil movement, earthquake or other structural impact or user damage

4. Proprietary stain systems and proprietary paint systems have not been evaluated, and are therefore outside the scope of this certification

5. The designer shall provide a signed Declaration for submission with the building consent application that the use of this product in the proposed building work falls within the intended used of the system as described in this certificate and that all design conditions of this certificate have been met.

6. The installer shall supply a signed Declaration that the product has been installed in accordance with the installation conditions of this certificate, for consideration for issuing a Code Compliance Certificate (CCC).

7. The system can only be used with the ancillary components and board profiles as described in the Applicable Technical Specification. Where these components are substituted with alternative products, these applications fall outside the scope of this certification. In particular, the System relies on the joinery meeting the requirements of NZS 4211:2008 including Amendment 1 for the relevant Wind Zone or wind pressure).

8. In existing buildings, the designer signing the declaration referred in condition #5 must be satisfied that the existing building is adequate for the intended building work. This assessment is outside the scope of this certificate.

9. With TMT Taiga RW, TMT Taiga WW and TMT Taxon TW weatherboards only stainless steel fixing can be used.
