GB/T 18570.11-2009 《Preparation of steel substrates before application of paints and related products - Tests for the assessment of surface cleanliness - Part 11: Field method for the turbidimetric determination of water-soluble sulfate》 Related products

This standard specifies a test method for evaluating the surface cleanliness of water-soluble sulfate on steel before coating using a field turbidity measurement method. The standard applies to the control and detection of surface cleanliness on steel surfaces after spray cleaning, especially before painting. This method provides a simple and effective tool for field operation to ensure that the steel surface meets the required cleanliness of the coating, which helps to improve the adhesion and durability of the coating.
