  6. The liability of BRANZ in respect of any claim for loss, damage or expense of any nature and howsoever arising shall in no circumstances exceed a total aggregate sum equal to 10 times the amount of the fee paid in respect of the specific service which gives rise to such claim or NZD$50,000 (or its equivalent in local currency), whichever is the lesser.
  7. BRANZ shall have no liability for any indirect or consequential loss (including loss of profits).
  8. In the event of any claim the Client must give written notice to BRANZ within 30 days of discovery of the facts alleged to justify such claim and, in any case, BRANZ shall be discharged from all liability for all claims for loss, damage or expense unless legal.

Thermal Resistance of an Insulation Sample


NRG Building Systems Pty Ltd, 30 Binary Street, Yatala, QLD 4207, Australia.


The test equipment used was a LaserComp Fox 600 heat flow meter.  The specimen for testing is placed horizontally in the apparatus, with upwards heat flow.  The hot and cold plates each have a 250 mm x 250 mm heat flux transducer embedded in their surface.  The edges of the specimen are insulated from the room ambient temperature.


The specimen was supplied by the client and consisted of  one piece of  light greenpolystyrene.  The dimensions of the sample were 595 x 595 mm.  It was tested at itsactual thickness, to the requirements of ASTM C518-04.


These measurements comply with the requirements of ASTM C518. The uncertainty in the measurements of thermal conductivity and thermal resistance are estimated to be ± 3%.
