ATDs and impactors are measurement devices used to assess the protective capacity of vehicles and restraints during impact events. These devices need regular certification to ensure that they meet design specifications, repeatability, and reproducibility requirements. The certification procedures, also called qualification procedures, are often simplified versions of biofidelity test conditions used in the original specifications. For each ATD and impactor, full body and/or component tests are defined. Frequency of certification testing may differ between applications and users are advised to refer to compliance and consumer information test programmes for information on this.
Cellbond offers rigs and fixtures for all of the impactors and dummies that we manufacture. For test fixtures such as probes and headforms, customised solutions are offered. This ensures that Cellbond equipment operates within existing laboratories belonging to our customers.
Cellbond is also involved in research into new advanced qualification methods. This sees ATDs and components loaded more closely to the conditions in actual crash tests. Examples include dynamic fixtures for the Q Dummy abdomens, and torsion jigs for Q Dummy rubber components.
