Rockatek provides a consultancy service into several industries where operating conditions are extreme and the price of failure is significant. Under these circumstances Rockatek carries out in-house qualification testing to verify complex design analyses and to demonstrate known failure modes to customers. Data from laboratory testing is typically used to refine simulations and analysis, increasing the level of confidence in any proposed solution.

In-house testing can also be carried out if a customer has not been able to reliably identify a true cause of failure. Laboratory testing under controlled conditions with the appropriate data acquisition system will typically result in a much greater understanding of component loading and potential failure modes.

To compliment laboratory testing or feed into Engineering analysis, Rockatek can coordinate on-site or in-service field testing with a broad range of data acquisition equipment and services.
