Standard Practice for Use of Pictorial Surface Preparation Standards and Guides for Painting Steel Surfaces

Importancia y uso:

4.1 The appearance of the various degrees of dry and wet abrasive blast cleaning, hand and power tool cleaning, and water jetting are influenced by the initial rust grades of the steel being cleaned and/or the type and condition of the coating on the existing steel. The standards and guides aid visually in judging and evaluating the degree of rusting and/or paint deterioration before cleaning and the degree of cleaning of steel surfaces prior to painting.

4.2 Five methods have evolved because of differences in the practice of using visual standards and guides throughout the world, and the method of surface preparation employed. In Europe, the visual standards (Method A) are used as the primary means of assessing the degree of cleaning. In the U.S., the SSPC written definitions take precedence with the visual guides and reference photographs used as a supplement. The visual guides and reference photographs of Methods B, C, and D conform to the SSPC written definitions. There are written definitions for Method E, however, the visual guide for Method E does not contain a complete set of pictorials corresponding to each surface cleanliness definition.
