5.1 This practice provides a means of assuring that products supplied during ship construction and maintenance are substantially the same as the materials on which the original selection was based. The selection of a paint for shipboard use frequently involves laboratory and field evaluations of candidate materials as part of the specification process. When a paint is selected, it shall have the same composition and characteristics throughout the delivery period as the materials originally evaluated.5.1.1 When significant changes in composition or paint characteristics are observed, it is necessary to determine the cause of the change (production error or formulation change) and its impact on coating performance. Actions to take if a formulation change is required are specified in 6.5.5.2 This practice is not meant to cover all possible chemical or physical tests that may be used to identify a coating. Additional tests may be needed to meet specific user needs.5.3 This practice does not recommend specific tolerance limits for the tests indicated. Tolerance values need to be agreed upon by the coating supplier, the shipbuilder, and the ship’s owner.5.4 This practice does not establish critical attributes that must be controlled. These attributes are selected by the shipbuilder and the ship’s owner based on specific needs (for example, colors).1.1 This practice provides the quality control receipt inspection procedures for protective coatings (paints) procured for end item use on ships and other marine structures. The practice includes methods and procedures for verifying that coating materials received are within the range of physical and chemical characteristics as those originally specified and tested.1.2 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.1.3 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.

4.1 To achieve success in ship construction, it is necessary for the ship owner and the ship builder to agree on the level of quality in the final product. Classification rules, regulatory requirements, and ship specifications all help to define an acceptable level of construction quality; however, this guidance alone is not sufficient. It is up to the shipbuilder, therefore, to describe the level of workmanship sufficiently that will be reflected in the delivered ship, and for the ship owner to communicate their expectations effectively for the final product.4.2 It is the intent of this document to contribute to these objectives in the following ways:4.2.1 To describe a reasonable acceptable level of workmanship for commercial vessels built in the United States.4.2.2 To provide a baseline from which individual shipyards can begin to develop their own product and process standards in accordance with generally accepted practice in the commercial marine industry.4.2.3 To provide a foundation for negotiations between the shipbuilder and the ship owner in reaching a common expectation of construction quality.4.3 The acceptance criteria herein are based on currently practiced levels of quality generally achieved by leading international commercial shipbuilders. These criteria are not intended to be a hard standard with which all U.S. shipyards must comply. Rather, they are intended to provide guidance and recommendations in the key areas that play a major role in customer satisfaction and cost-effective ship construction.1.1 This practice consists of three annexes: hull structure, outfitting, and coating. The subject of these annexes was selected for several reasons. Other commercial shipbuilding nations already have in place widely recognized standards of expectations in these areas. These constitute the most significant areas where workmanship is a critical factor in customer satisfaction. The cost associated with the labor involved in these three areas is a significant factor in construction man-hours and overall schedules.1.2 The standard criteria provided in this practice are intended to apply to conventional, commercial ship construction. In many cases, specialized, nonconventional vessels using nonstandard materials or built-to-serve sole requirements may require unique acceptance criteria that are beyond those provided in this practice.1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.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.

This guide has been developed to aid naval architects, ship designers, material and equipment suppliers, buyers, ship owners and operators, and government agencies by providing pertinent information in one document that can be used during various stages of commercial shipbuilding. These stages include design, planning, purchasing, material fabricating, assembling, testing, quality assurance, and inspection.This guide is a non-technical document, meaning that it does not specify how a particular standard is to be implemented by any person or agency. Local or national regulatory agencies having jurisdiction and oversight of ship design and operations may incorporate all or part of any particular standard in their regulations.There may be more than one standard listed for a particular product, test, or specific application. However, this guide does not compare the different standards or specify which particular standard should be used.A partial list of sources for obtaining various standards is included below. Other sources may be located by contacting various information centers such as those at ASTM, the National Institute for Standards and Technology (Codes Standards and Information), and the American National Standards Institute. Information is also available through various sites on the Internet World Wide Web (for example, http://www.webplus.netnssn). When ordering, organizations should consider obtaining the latest copies of standards as complete sets or portions of sets in whatever media are appropriate (for example, hard copy, CD-ROM, or microform) since purchasing, quality assurance, and engineering departments are frequently looking for information about standards called out in contract specifications, and these standards vary from one contract to another. The abbreviations used in Table 1 are defined in here in this paragraph. Some of the sources for ordering standards are:AbstractThis guide is a listing of relevant publications, standards, and other information related to commercial shipbuilding.

This specification provides the testing and performance requirements for fiber-reinforced polymer (FRP) gratings used in marine construction and shipbuilding to ensure personnel safety. It is intended for use by all persons designing, manufacturing, testing, inspecting, and maintaining FRP gratings. It does not address the ability of the gratings to support either moving or stationary equipment during or after a fire exposure, as well as hydrocarbon pool or jet fire exposures.This specification covers test requirements that must be met, namely: deflection limits, assembled grating ultimate failure, wheel loading, assembled panel impact resistance, skid resistance, durability, ultraviolet resistance, salt spray, surface flammability, and structural fire integrity.1.1 This specification provides the testing and performance requirements for fiber-reinforced polymer (FRP) gratings used in marine construction and shipbuilding as an equivalency to the specification of steel gratings rated for a maximum load of 94 lbf/ft2 (4.5 kN/m2).1.2 The purpose of this specification is to ensure that all FRP gratings are designed and tested appropriately to ensure personnel safety.
