It means the manufacturer is referring to formal performance testing rather than relying only on how the underlay feels in a showroom. Airstep states that its carpet underlays are scientifically tested to perform in accordance with relevant Australian Standards guidelines. For a customer, the useful follow-up is to ask which standard and test result applies to the exact product being quoted, because different underlays can be designed for different residential, commercial, acoustic or other performance requirements. Current certificates or technical data should be used where a project has a specific compliance requirement.
