OBD Approval Process

2012-01-24
The OBD approval process can be a frustrating time for both manufacturer and ARB staff. For manufacturers, a long approval process can sometimes mean accepting deficiencies prematurely in exchange for an approval. For ARB staff, they are inundated with highly technical information which they must review, garner understanding of and then apply their experience to evaluate it for compliance. OBD approval anxiety can be minimized, if not avoided, when manufacturers understand ARB�s expectations. This presentation will take you through some unwritten rules and common pitfalls which can impede the approval process, thus providing a guideline to a less painful and more efficient certification document review and approval.
