In heavy-duty coating painting completion inspection and acceptance, often in 90-10 film thickness acceptance standard, requires both the film thickness, which was more than 90% of the measuring point measured values must meet or exceed the specified film thickness value, the rest of the film thickness, which was less than 10% of the measuring point measured value shall not be less than 90% of the film thickness specification. Select a representative point, generally the area of the tested area, should be greater than or equal to 5% of the total area of the coating. There are many factors that related to the service life of coating: use varieties of paint, paint quality, surface treatment, construction quality and coating using the environment, and so on. Here are some extracts from the American association of corrosion engineers (NACE) according to the practical experience is given under the conditions of the service life of the paint tables.
