The repair expenses after a car accident, such as painting the car body, is usually paid by an insurance company. To simplify the process of valuation of expenses, The Norwegian Financial Services Association and The Norwegian Association of Motor Car Dealers and Service Organisation (NBF) have agreed on using a standard system to calculate the length of time taken for a paint job of a certain type. The standard times are based on time studies of several paint jobs conducted at Norwegian garages. NR has evaluated the methodology used for calculating the standard times, especially with respect to the representativeness of the paint jobs used in the time studies.
