    Significance and Use

    3.1 This practice may be invoked by any of the parties mentioned in 1.2 and may be included as part of a specification or used to clarify or reinforce an existing specification that does not adequately address inspection. When invoked by the ship owner on the shipbuilder, the shipbuilder is responsible for the coordination effort.

    3.2 As surface preparation and coating requirements generally differ from ship area to ship area, this practice shall be applied separately to those areas of similar requirements.

    3.3 The contents of this practice shall be addressed (for each applicable ship area) at a prestartup meeting attended by the parties mentioned in 1.2.

    1. Scope

    1.1 This practice is intended to serve as a guide for determining specific inspection requirements for marine surface preparation and coating application during new construction, major retrofit, or routine maintenance contracts.

    1.2 It is intended that this practice be used to coordinate inspection activities between ship owner, ship builder, coatings manufacturer and coatings applicator, and that specific requirements be developed before the commencement of surface preparation or coating application, or both.

    1.3 This practice does not provide a means of recording required data (for example, film thicknesses, temperatures, relative humidity, and so forth), but instead establishes a format for deciding what data must be recorded, when during the preparation/coating process, and by whom.

    1.4 This practice does not establish accept/reject criteria for surface preparation or coating inspection, nor does it address methods of repairing deficiencies found. It does, however, provide a means of determining them.

    1.5 This standard may involve hazardous materials, operations, and equipment. 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 and health practices and determine the applicability of regulatory limitations prior to use.
