Timber Testing NZ

The IVS Timber Preservation Testing Service has been developed to provide accurate and rapid test results for timber treatment providers. IVS is accredited to the ISO/IEC 17025 : 2017 International Standard providing a high quality service.

We deliver:

  1. An Independent Testing Programme - to provide accurate timber treatment analysis. We are accredited to ISO/IEC 17025 : 2017 International Standard
  2. Fast Turnaround - a five day maximum return on testing results will minimise disruption to your process supply chain enabling the treatment plant operator to identify and address issues quickly

  3. Risk Calculation - IVS provides a risk calculation which measures the probability of the timber treatment falling below the minimum Hazard Class requirement using timber sample variability and average treatment retention results timber density data from tested samples and average retention results, we assist you to calculate the probability that timber will fall below the minimum retention required

  4. Accuracy - IVS participates in an industry recognised Interlaboratory Comparison Programme. The outcome of this provides assurances that our testing is accurate

  5. Precision - through repeat testing of a quality control (QC) sample and reviewing the variability, we can determine the uncertainty of measurement (UOM) associated with our results. This information is available on request

  6. Better Reporting - IVS reports will provide you with clear and quantitative data showing the retention and penetration achieved for each sample checked. The analysis report provides a graphical representation of results including:

    • Mass / Mass result for active chemicals analysed
    • Preservative penetration
    • Variables / Trends
    • Historical data
    • Risk calculation (we can calculate the probability of timber falling below the minimum retention required).

Their combined commitment to a fast turnaround time of accurate analytical results provides timber treatment companies not only an independent verification of their quality systems; but also the ability to fine tune their preservative treatment operations. This saves time, money, minimises wastage, without compromising on the quality and durability of their timber.
