Those meth-ods are fineness of grind, contrast ratio measurements6 for opacity and trans-parency, color strength and shade de-velopment, gloss, particle size measure-ment by light scattering, rheology, and optical microscopy. This module forms the concluding part of the modular course run in 1992 and aims to look at some of the things that go wrong with paint: There are two main areas where things can go wrong: (1) During or immediately after application where the reasons for failure can usually be determined. The SRB's aims are to operate in the public interest, and to develop the technical and ethical competence of the profession and its ability to deliver ethical practice to high standards globally. The RICS Rules of Conduct set high-level professional requirements for the global chartered surveying.

Surface irregularities, typically appearing as ripples, curved, straight or crisscrossed grooves, or jagged or globular protrusions. This standard requires the ability to undertake the complete rectification process, including the preparation and application of foundation.
