Significance and Use | ||||||||||||||||||||
5.1?In performing maintenance of a coating system, the new coating being applied must be compatible with the existing coating. While general guides exist which indicate compatibility of different generic types of coatings, differences in manufacturers formulation and the condition of the in-place coating system may affect compatibility. |

1. Scope | ||||||||||||||||||||
1.1?This practice covers the procedures for assessing coating compatibility when maintenance of an in-place coating system is being contemplated. It does not address procedures for assessing the integrity of the existing coating to determine if it can be repainted, nor does it establish the compatibility of the maintenance coating system with the substrate or corrosion products. The practice is intended for use in the field. SSPC-TU 3 discusses the risks associated with the maintenance painting practice known as overcoating. Note 1:?Pass-Fail Criteria (for example, adhesion
requirements) are not established by this practice. These should be
established by the user or specifier with input from the coating
manufacturer.
1.2?The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.3?This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
