scope:

This Part of IS0 8130 is one of a serieso f standardsd ealingw ith the samplinga nd testing of paints,v arnishesa nd relatedp roducts. It specifiesa methodf or determ ining the flow characteristicosf a fusedt hermosettingc oating powder down a plane inclined at a set angle to the horizontal. The result of the test describedin this Part of IS0 8130 givesa n indicationo f the degreeo f melt flow that may occur during the curing of the coating powder. This characteristic contributest o the coherenceo f the coating,t o its surfacea ppearancae nd to the degreeo f coverage over sharp edges. The test acts as a useful method for checking for batch to batch variation in the behaviour of a given coating powder. Correlation between the results from coating powders of differing composition is not to be expected. This method is unlikely to yield meaningful results with coating powders which have gel times of less than one minute at the test temperaturew hen characteriseda ccordingt o IS0 8130: Part 6.
